All PDF: Reader, Editor

All PDF: Reader, Editor is the kind of Android tools app that sounds simple until you need to open an important document quickly, convert it, or work out why a file is not behaving as expected. I spent time looking at it as an everyday PDF utility rather than as a full office suite, and my impression is fairly clear: it is most useful when you want one place for basic PDF viewing and document conversion, without paying to get started.

That focus matters. The app is developed by Shkor and sits in the tools category, with a free download and an Everyone age rating. Its current version is 1.0.3, and it runs on Android 8.0 or newer. I would not approach it expecting a complete replacement for a desktop document editor. I would approach it as a practical helper for opening PDFs and handling straightforward document tasks on a phone.

Where people are most likely to get stuck

The first point of friction is usually not the PDF itself but finding the right file. On a phone, documents may arrive through email, messaging apps, cloud storage, a browser download, or a file manager. If you open the app before the file has finished downloading, or if you look in the wrong folder, it can feel as though the reader has failed. My first recommendation is simple: check that the document is actually stored on the device, then use the Android share or open-with option if the file does not appear immediately inside the app.

This is especially relevant with files received as attachments. Tapping a preview in an email does not always save a usable local copy. If All PDF: Reader, Editor cannot open that preview, download the attachment first and try again from the Downloads folder. That small distinction prevents a lot of unnecessary reinstalling.

A second common stumbling block is confusing viewing with conversion. Opening a PDF and changing a document into another format are different jobs, even when they are placed within the same utility. A PDF may display correctly while a conversion takes longer, produces a different layout, or needs a clearer source file. I would test the reading side first, then handle conversion as a separate step rather than assuming that a successful preview guarantees a perfect converted document.

There is also a practical difference between text-based PDFs and scanned pages. A document made from selectable text is generally easier to work with than a scan that is really a collection of images. If you cannot select words in another reader, the problem is probably related to how that PDF was created, not necessarily to this app. That is an important expectation to set before using any conversion tool.

The app’s average rating is 3.5 from roughly 660 ratings, while the number of written reviews is only around 20. I read that combination as a reason to keep expectations measured. It suggests that people have had mixed experiences, but it does not tell me that every task will be unreliable. For a newer, focused utility, I would judge it by the particular workflow I need rather than by the rating alone.

Start with a small, ordinary document

When I try a document tool for the first time, I avoid beginning with a long contract, a school archive, or the only copy of an important form. A better test is a short PDF that is easy to replace. Open it, move through several pages, and try the exact conversion you expect to use. This reveals whether the app fits your routine without putting valuable files at risk.

A useful test file should contain the kind of content you handle most often. If your documents are mostly letters and invoices, use one of those rather than a highly designed brochure. If you regularly receive scans, test a scan. The result will tell you more than a generic sample because PDF behavior depends heavily on the source document.

Setup checks that save time later

Because the app is free and the minimum Android requirement is 8.0, compatibility should be straightforward for many users, but I would still check the phone’s Android version before spending time troubleshooting. The version number is found in the device settings, usually under system information. If the phone is older than the requirement, installation or normal operation may be the real issue.

After installing, I would keep the first setup deliberately simple. Open a known PDF from local storage, confirm that pages render, and only then try sharing a file into the app. This order helps separate three different problems: an unavailable file, a device-level opening issue, and a problem with the document itself.

File names can also create confusion. A document with a misleading extension, an incomplete download, or a name that contains unusual characters may not behave like a normal PDF. Renaming a copy with a short, clear name can be a useful diagnostic step. I would not overwrite the original; keeping the original untouched makes it easier to compare results.

Storage location is another overlooked detail. A file may appear in a messaging app but not yet exist in the folder you expect. I would use the phone’s file manager to confirm its location and size, then open that saved copy. If the document is on removable storage or inside a cloud provider, copying it into local storage can help determine whether the issue is access to the location rather than PDF support.

For conversion, I would prepare the source before opening the tool. Remove accidental duplicate pages, make sure the file is complete, and use the clearest original available. Converting a compressed screenshot of a document is a poor test of any converter. The more work the app has to reconstruct from an image, the more likely the output is to need manual checking.

Use the share route when browsing becomes awkward

One of the more useful workflow ideas is to treat the Android share sheet as an alternative entry point. If the document is already open in a file manager, email app, or browser, sharing it directly to All PDF: Reader, Editor may be quicker than navigating through several folders. This is not a magic fix for a damaged file, but it reduces the chance of selecting an old duplicate or an incomplete download.

I would also keep converted files clearly separated from originals. A simple naming habit such as adding “converted” and the date to a copy makes it much easier to identify the result later. It also protects the original when you need to repeat the operation with a different source. This is a small practice, but it matters on a phone where several similarly named documents can quickly become confusing.

Recovering a workflow when something goes wrong

If a PDF refuses to open, I would work through the problem in a fixed order instead of repeatedly tapping the same file. First, close and reopen the app. Next, try a second PDF that you know is valid. If the second file opens, the original is the likely cause. If neither opens, restart the phone and try again from local storage. These checks are basic, but they identify whether the failure follows the file or follows the app.

When a document opens as a blank page, wait briefly and move between pages before deciding it has failed. Some files are more demanding than others, particularly when they contain large images or complicated layouts. If the result remains blank, compare it with another reader on the same device. A blank result in multiple readers points toward the file; a problem limited to one app points toward compatibility or app handling.

For conversion problems, keep the original and inspect the output as a new document. Check page order, headings, line breaks, tables, and any images that carry important information. A converted file can look acceptable at a glance while still losing spacing or changing the position of a signature. I would never send a converted legal, financial, or work document without reviewing every page that matters.

If the app appears frozen during a task, avoid immediately clearing all app data. Start by waiting, then close the app normally if possible and reopen it. If the issue repeats with one large or unusual file, test a smaller document. Clearing data can remove local state or recent choices, so I would reserve that step for a last-resort troubleshooting action and make sure the source files are safely stored elsewhere.

Another practical recovery method is to create a fresh copy of the source document. A file can be readable in one location but incomplete in another because a download was interrupted. Downloading it again or exporting a new copy from the original application may solve the problem without changing any setting in the PDF reader.

When the output needs a second tool

All PDF: Reader, Editor makes the most sense as a first step, not necessarily the final step, for document work. If you need advanced page design, detailed annotations, reliable form filling, electronic signatures, or collaborative editing, a dedicated office or PDF platform may be a better match. The usual alternative of using a browser-based converter can handle some formats, but it may be slower on a phone and less convenient when you are working with files that should remain local.

Dedicated PDF readers can also be preferable when your priority is intensive reading. They may offer stronger navigation tools, bookmarks, accessibility controls, or specialized annotation features. On the other hand, installing several separate utilities creates its own inconvenience. If your needs are mainly opening PDFs and occasionally converting documents, one focused app can be easier to keep around than a collection of narrowly designed tools.

The trade-off is therefore convenience versus depth. This app’s appeal is having viewing and conversion in one free utility. Its weaker fit is for people who expect a polished document-production environment. I would choose it for quick handling on Android, but I would move to a more specialized option when the document is important enough that layout control and editing precision matter more than simplicity.

When the app is not the cause

It is easy to blame the reader when a document looks wrong, but PDFs preserve the decisions made when they were created. Missing fonts, unusual page sizes, password protection, damaged downloads, and scanned images can all affect what happens after opening. If the same file shows the same problem elsewhere, the source deserves attention before the app does.

Conversion has an additional complication: not every PDF contains editable text. A scanned receipt may look like text to your eyes but behave like a photograph to software. In that situation, a normal conversion may preserve the page as an image rather than recreate every word as editable text. I would use a document that contains genuine selectable text when testing the conversion workflow, then decide whether the result is good enough for the intended purpose.

Network conditions can also confuse the diagnosis when files are being retrieved from online storage. If the document has not fully synchronized, the app may receive an incomplete copy. Saving the file locally before opening it removes that variable. This is one of the safest general checks because it does not require changing permissions or making risky system adjustments.

Finally, device storage and background activity can affect any document utility. If the phone is nearly full, keeping a clean copy of the source and output becomes harder. I would free enough space for the files involved, close unrelated apps, and retry with a small document. That is more sensible than assuming that every failure reflects a defect in Shkor’s app.

A realistic everyday example

Imagine receiving a rental form as a PDF while away from a computer. I would download it fully, save a copy with a clear name, and open it in All PDF: Reader, Editor to check that every page is present. If I need another document format, I would run the conversion on the saved copy, then compare the output with the original before sending it. If the form is a scan, I would pay particular attention to whether the result remains an image and whether any boxes or signatures have shifted.

That workflow shows where the app is genuinely helpful: it puts quick document access and conversion on the phone. It also shows its limits. If the form requires precise interactive fields, a signature workflow, or complex layout changes, I would stop treating this as the only tool and use an option designed for that job.

My practical verdict

All PDF: Reader, Editor is worth considering if you want a free Android tool for opening PDFs and handling basic document conversion. Its broad reach is reflected in more than one hundred thousand installs, but the mixed average rating tells me to use it with realistic expectations. I like the idea of keeping common PDF tasks together, especially when I am away from a computer and do not want to juggle several utilities.

My main advice is to test your own document type before trusting the app with an important conversion. A simple text PDF may be a smooth experience, while a scan, a protected file, or a heavily designed document can expose limitations that are not visible in a quick preview. Keeping originals, working from local copies, and checking the converted result page by page makes the app much safer to use.

I would recommend it to students, casual Android users, and anyone who mainly needs a lightweight PDF viewer with conversion available when required. I would skip it as a primary document workspace if I needed advanced editing, dependable form tools, extensive annotation, or professional layout control. In those cases, the usual specialized alternatives justify their extra complexity.

For the right situation, All PDF: Reader, Editor is a sensible utility rather than an all-purpose office replacement. The free price lowers the barrier to trying it, the Everyone rating makes it approachable for general use, and the current 1.0.3 release gives users a straightforward starting point. I would keep it as a practical option for quick PDF jobs, while remembering that the quality of the source file often matters just as much as the app handling it.
