Best Pdf Editor Apps for Android (2026)
Editing a PDF on a phone used to feel like a compromise, but the apps below have closed most of the gap with desktop tools. We spent weeks signing contracts, marking up reports, and merging scanned pages on a range of Android devices to see what actually holds up. These are the PDF editors we kept coming back to, and you will find more document tools in our Productivity apps hub. To turn paper into editable files first, pair one of these with a solid scanner app, covered below.
1. Adobe Acrobat Reader: Edit PDF
This is the one most people should try first. In our testing the free tier handled highlighting, comments, and filling forms without nagging us too much, and signing a document took seconds. The paid plan unlocks real text editing and page reordering. It syncs cleanly with cloud storage, and the reading view stays crisp on smaller screens. A safe, polished default.
2. Xodo PDF Reader & Editor
Xodo is a strong free pick for reading and marking up files. Annotating is fast, the markup tools are responsive, and it chewed through big, image-heavy PDFs that made other apps stutter. One thing changed in 2026 that you should know: the free tier now stamps a watermark on shared or exported documents unless you pay, even on files you did not create in the app. So it is great for on-device viewing and notes, but check the export before you send anything official.
3. WPS Office
If you juggle documents and spreadsheets alongside PDFs, WPS keeps everything under one roof. We used it to convert a Word file to PDF, tweak a few lines, and send it back out without switching apps. The PDF editor covers annotation, signing, and basic page tools. The ads on the free tier got heavier in 2026 and can interrupt you mid-task, but for an all in one office companion it still earns its place.
4. Foxit PDF Editor
Foxit feels built for people who live in PDFs all day. During testing the editing tools were genuinely capable, letting us change existing text and rearrange pages with more confidence than most mobile apps allow. The 2026 version added OCR and an AI assistant behind the subscription. It is a heavier app and the interface takes a moment to learn, but the payoff is desktop grade control. Worth a look if you handle documents professionally.
5. Microsoft 365 Copilot
This is the app formerly called Microsoft 365 (Office), renamed and rebuilt around Copilot in early 2026. You can still sign, annotate, and turn photos or Word files into PDFs tied to your account. Be aware that Microsoft is winding down in-app editing of Word, Excel, and PowerPoint here and pushing you toward the standalone apps instead, so treat it as a markup and conversion helper rather than a deep editor. It fits naturally if your workflow already runs through Outlook and OneDrive.
6. PDFelement
PDFelement strikes a nice balance between power and approachability. We edited text, swapped images, and filled forms without hunting through cluttered menus, which is rarer than it should be on mobile. The OCR feature did a respectable job pulling text out of scanned documents. A subscription unlocks the heavier tools, but the layout stays friendly enough that newcomers will not feel lost.
7. Smallpdf: Scanner & PDF Editor
Smallpdf takes a task first approach that we found refreshing. Instead of one busy toolbar, you pick what you need, compress, convert, merge, or sign, and the app guides you through it. In practice this made quick jobs genuinely quick. It leans on cloud processing, so a connection helps, and a free account has daily limits. Great for occasional, focused PDF chores, less so for sensitive files you would rather not upload.
8. iLovePDF: PDF Editor & Scanner
iLovePDF packages a large toolbox of conversions and edits into a tidy app. We merged, split, watermarked, and compressed files in a single sitting, and each tool did exactly what it promised. Signatures and annotations are covered too, and OCR is available for turning scans into text. The free tier handles light use, with limits that bite once you process large batches. A reliable utility belt for routine document work.
9. PDFgear: PDF Editor & Reader
PDFgear is the rare free app that genuinely edits existing PDF text, and it does it without a watermark or page cap. In testing we tapped into a paragraph, changed words, and adjusted fonts directly, no conversion dance required. It also annotates, fills forms, and signs. Complex layouts can shift a little when you edit, and it leans on its own AI features for some tasks, but for straightforward text fixes at no cost it is a genuinely useful pick.
10. MobiPDF (formerly PDF Extra)
MobiPDF, the app MobiSystems used to call PDF Extra, rounds out our picks with a clean feel and a solid spread of features. We signed documents, added comments, edited text, and ran OCR on a scan comfortably, and the reading experience was easy on the eyes. It pushes a subscription for the advanced editing tier, but the everyday tools are accessible and the design never got in our way. A capable option worth trying free first.
How to choose a PDF editor for Android
Here is the thing most app stores will not tell you plainly: the majority of so-called PDF editors on Android are really annotators. They let you draw on top of a page, drop a comment, highlight a line, or stamp a signature. That is useful, but it is not the same as changing the words that are already printed in the document. True text editing is the dividing line, and it is the single feature people most often expect and most often do not get. So before you settle on an app, be honest about which side of that line your task falls on. Marking up a report and signing a lease need very different tools than fixing a typo buried in a contract someone else made.
The features that actually matter
A handful of capabilities separate a good fit from a frustrating one, and they are worth understanding before you install anything.
Annotate vs. true content editing. Editing existing text is hard on a phone for a real technical reason: a PDF does not store a flowing document the way a Word file does. It stores text as glyphs placed at fixed coordinates on the page. To change a word, the app has to find those glyphs, re-flow the line, and match the font, which is genuinely difficult work. The apps on this page that actually pull it off are Foxit, PDFelement, MobiPDF, and the free PDFgear. Everything else is markup.
OCR for scans. OCR, optical character recognition, looks at a picture of text and works out what the letters are so the text becomes selectable and searchable. You need it any time your PDF is really a photo, like a scanned receipt or a contract someone snapped with their camera. Accuracy is good but not perfect; expect mistakes on faint print, odd fonts, or handwriting, and always proofread the result. PDFelement, iLovePDF, Foxit, and MobiPDF all offer it.
Signing and form filling. There are a few kinds of signature. A drawn one is your finger or stylus scrawl, a typed one is your name in a script font, and a certificate signature is cryptographically tied to your identity for legal weight. Most people want to draw or type, save that signature once, and reuse it. Forms matter too: a proper interactive AcroForm has real fields you tap and type into, while a flat form is just a flat image you have to lay text boxes over. Adobe and MobiPDF handle both well.
Merge, split, compress, convert. These are the utility-belt jobs, combining two PDFs, pulling out a page, shrinking a file to fit an upload limit, or turning a PDF into Word. iLovePDF, Smallpdf, and MobiPDF are the tools to reach for here.
Offline vs. cloud processing. Some apps do their work right on your phone; others upload your file to a server and send it back. On-device is better for privacy and works with no signal. Cloud tools can be faster for heavy conversions but need a connection and, well, the cloud.
Privacy: where your documents actually go
This part gets skipped too often. When you use a cloud-based tool like Smallpdf or iLovePDF, your file leaves your phone and lands on a company server while it is processed. For a meme or a flyer, who cares. For a signed contract, a passport scan, a medical letter, or a bank statement, that is your sensitive paper sitting on someone else's computer. On-device editors like Foxit, PDFelement, and Adobe's local editing keep the file on the phone, which is the safer default for anything private. Pay attention to whether an app forces you to create an account or sign in before it will do basic work, since that ties your documents to a profile. Look for whatever the app says about data retention and deletion, how long they keep your upload and whether you can wipe it. The practical habit: before you trust any app with something sensitive, walk through its export or share flow once with a throwaway file and watch where it asks to send things. If it quietly uploads, you will know.
Free vs. paid: what the money actually buys
The paywall lines in 2026 are fairly consistent across these apps. Free almost always covers viewing, annotating, signing, and filling forms. What you pay for is the harder stuff: editing existing text, OCR on scans, batch conversions, and the removal of watermarks or daily caps. A few specifics worth knowing this year. Xodo's free tier now puts a watermark on documents you share or export unless you subscribe, which caught a lot of long-time users off guard. Cloud tools like Smallpdf cap how many files you can process per day on a free account. WPS is free but the ad load has grown heavier and more interruptive. PDFgear is the outlier that still edits text for free without a watermark. Most paid plans here are subscriptions rather than one-time purchases, so factor in the recurring cost; a few, like PDFelement and MobiPDF, do offer a perpetual license if you would rather pay once.
Common mistakes to avoid
- Assuming any app labelled PDF editor can change existing text. Most only annotate. Confirm the feature by name before you rely on it.
- Signing a contract in the wrong tool and getting a watermark stamped across it. Check the exported file before you send, especially on Xodo's free tier now.
- Uploading a sensitive document to a cloud tool without checking what happens to it afterward. For IDs and financial papers, prefer an on-device editor.
- Trying to edit a scanned image-PDF without running OCR first. If the text is not selectable, the app is seeing a picture, not words.
- Treating conversion to Word as a way to edit. It often mangles the layout, and you spend longer fixing the formatting than the change was worth.
- Not opening the finished file before you send it. A quick look catches a stray watermark, a missed field, or a signature that landed in the wrong spot.
Our bottom line
For most people, start with Adobe Acrobat Reader for its dependable free signing and markup. If you need to change actual text without paying, PDFgear is the free pick to try; if you do it for a living, Foxit or PDFelement are worth the subscription.

Frequently asked questions
Can I edit the actual text inside a PDF on Android?
Yes, but it depends on the app. Tools like Foxit, PDFelement, MobiPDF, and the free PDFgear let you tap into existing text and change words directly. Many free apps only allow annotations and comments on top of the page rather than true text editing, so check that the app lists content or text editing before you rely on it for that.
What is the best free PDF editor for Android?
It depends on what you need. Adobe Acrobat Reader is excellent for free if you mainly comment, fill forms, and sign. If you need to change existing text at no cost, PDFgear is the standout, since it edits text without a watermark. Note that Xodo, long a free favourite, now adds a watermark to shared or exported files unless you pay. For a full guide to no-cost options, see our roundup of free Android PDF editors.
Do these apps work offline?
Many do, but not all. Foxit, Adobe, and PDFelement handle most editing on the device itself, so you can work without a connection. Cloud-based tools like Smallpdf and iLovePDF process some tasks online and need internet for those features. If offline access matters, pick an app that does its editing locally. Need to scan documents to PDF first? Our best scanner apps for Android pair well with these editors, and the best office suite apps for Android help if you also handle Word files and spreadsheets.
How do I sign a PDF on my Android phone?
Open the file in an editor that supports signatures, such as Adobe Acrobat Reader or MobiPDF, tap the signature tool, then draw with your finger or stylus or type your name. You can save the signature for reuse and drag it onto the right spot. Export the signed copy and check it before you share, since some free tiers add a watermark on export.
