Editing PDFs on Android used to mean emailing the file to your desktop, making changes there, and sending it back. That workflow is dead. I’ve spent the last month testing every halfway decent PDF editor on my Pixel 8 and Samsung Galaxy S24 to find out which apps actually let you edit text, annotate, fill forms, and sign documents without paying a subscription.
Here’s what works in 2026 – and what’s a waste of storage space.

What “Edit PDF” Actually Means on Android
Before diving into individual apps, let me clarify something that trips people up. There are different levels of PDF editing:
Level 1 – Annotations: Adding highlights, comments, drawings, sticky notes on top of the existing content. Almost every free app does this well.
Level 2 – Form filling and signing: Tapping form fields and typing in your info, drawing or importing a signature. Most free apps handle this.
Level 3 – Actual text editing: Changing the words already in the PDF, modifying fonts, moving paragraphs. This is where free options get scarce on Android. Only a few apps offer it without a subscription, and even those have limits.
Level 4 – Page manipulation: Reordering, deleting, rotating, or merging pages. Some free apps allow basic operations; others lock this behind a paywall.
Most people searching “edit PDF on Android” actually need Level 1-2. If that’s you, you have plenty of solid free options. True text editing (Level 3) on mobile is still limited compared to what you’d get on a free iPhone PDF editor or desktop tool.
Xodo PDF Reader & Editor – Best All-Around Free Option
Xodo has been my go-to PDF app on Android for about two years now. The interface is clean, it opens large files fast (tested with a 200MB architectural drawing – loaded in under 4 seconds on my Pixel 8), and the annotation toolkit is genuinely good.
What you get free:
- Highlight, underline, strikethrough text
- Freehand drawing with pressure sensitivity
- Text boxes, sticky notes, stamps
- Fill PDF forms (both interactive and flat)
- Electronic signatures
- Bookmark pages and add comments
- Cloud sync with Google Drive, Dropbox, OneDrive
What’s locked behind Xodo Pro ($8.99/month): true text editing, OCR, PDF to Word conversion, and unlimited exports. The free tier limits you to 2 annotated document exports per day, which honestly is enough for most personal use.
One thing I appreciate about Xodo – it doesn’t add watermarks to your free exports. That’s rare. The file you save looks exactly like what you’d get from the paid version, just limited in daily count.
Adobe Acrobat Reader – Best for Form Filling
Adobe’s free Android app won’t let you edit existing text (that requires Acrobat Pro at $12.99/month), but for everything else, it’s solid. The form detection is the best in class – it identifies fillable fields even in flat PDFs that weren’t designed as forms.
I tested it with a government tax form (IRS W-9) that had no interactive form fields. Adobe Reader recognized all the blank lines and let me type directly into them. Xodo needed me to manually place text boxes in those spots.
The signature feature uses Adobe Sign, which means your signed documents get a tamper-evident certificate. For legal documents, that matters. You get unlimited free signatures.
The downside: Adobe pushes its subscription hard. Every third action seems to prompt you toward Pro. And the app itself is 250MB+ installed, which is chunky for what it does on free tier.
Google Drive + Google Docs – The “Good Enough” Method
This isn’t an app recommendation so much as a technique everyone with an Android phone already has available. Upload your PDF to Google Drive, tap it, select “Open with Google Docs.” Google converts it to an editable document.
The catch: formatting often breaks. Tables get mangled, columns collapse, headers shift. For simple text-heavy PDFs (letters, contracts without complex layouts), it works surprisingly well. For anything with graphics, columns, or precise layout – forget it.
After editing in Docs, you can re-export as PDF via File > Download > PDF. The result won’t look identical to the original, but the text content will be correct.
When this works well: editing a one-page letter, fixing a typo in a simple report, updating text in a plain document.
When it doesn’t: anything with tables, multi-column layouts, embedded images, or specific font requirements.
iLovePDF – Best Web-Based Option for Android
iLovePDF has a native Android app, but honestly the mobile web version at ilovepdf.com works just as well and doesn’t eat your storage. You upload a PDF, make your edits in the browser, and download the result.
The free tier gives you 1 task per day (a “task” is one editing session on one file). The toolset is broad: you can add text overlays, images, shapes, draw freehand, stamp, and sign. It also does PDF compression, splitting, and merging on the same platform.
You won’t get true text-in-place editing on the free tier. You’re adding new text on top of the existing content. For covering up old text and writing new content, that works. For surgical single-word changes deep in a paragraph, not really.
File size limit: 100MB on free, which covers 99% of normal PDFs.
Foxit PDF Editor – Best for Power Users (with Trial)
Foxit offers a 7-day free trial of their full editor, and after that it’s $9.99/year (not month – year). That’s honestly a reasonable price if you edit PDFs regularly on your phone. During the trial, you get everything: true text editing, image insertion, page reordering, OCR, and form creation.
The text editing engine is noticeably better than competitors on Android. It preserves the original font when you modify text (most apps substitute a similar-looking font), and it handles reflowing text within paragraphs correctly. I edited a middle sentence in a long paragraph and the surrounding text adjusted naturally.
After the trial expires, you keep basic annotation and form-filling features free. The app doesn’t become useless – it just loses the pro editing capabilities.
File handling is fast. On my Galaxy S24, opening a 50-page report took about 2 seconds. The interface has a learning curve though – there are many toolbars and menus that can feel overwhelming on a phone screen.
Microsoft 365 (Office App) – Hidden PDF Trick
The Microsoft 365 app (formerly Office) on Android has a lesser-known PDF feature. You can open PDFs and convert them to Word format for editing, then export back to PDF. It’s essentially the same engine as desktop Word’s PDF converter.
The conversion quality sits between Google Docs and Adobe Pro. Tables are preserved more often than with Google Docs, but complex layouts still break. Headers and footers usually survive intact.
The free tier limits: files up to 10MB, basic formatting preservation. For larger files or better conversion fidelity, you need a Microsoft 365 subscription ($6.99/month).
This method makes sense if you already have the Microsoft 365 app installed for Word/Excel/PowerPoint. Adding PDF editing as a bonus feature costs nothing extra.
SmallPDF – Best for Quick One-Off Edits
SmallPDF’s Android app mirrors their web tool. You get 2 free tasks per day, and the editor handles basic text overlay, shape drawing, highlighting, and form signing.
The strength here is simplicity. Open the app, tap “Edit PDF,” pick your file, and you’re editing within 3 seconds. No account creation required for the first use. No confusing menus. The toolbar shows exactly what you can do: text, image, shape, draw, sign.
Limitations on free: no true text editing (overlay only), watermark on some exported files (intermittent – I saw it about 40% of the time), and the 2 tasks/day cap. If you go over, it asks you to wait 24 hours or subscribe at $9/month.
PDFelement by Wondershare – Best for Text Editing (with Watermark)
PDFelement is technically free to use for editing – and it genuinely lets you edit existing text in PDFs, change fonts, resize images, move paragraphs. The catch is every file you save from the free version gets a “PDFelement” watermark in the corner.
For personal use where watermarks don’t matter (editing notes for yourself, modifying internal documents), it’s actually the most capable free option for Level 3 text editing on Android. The OCR works offline, the text recognition is accurate for English and most European languages, and it handles multi-page documents without crashing.
The subscription to remove watermarks costs $79.99/year, which is steep for a mobile app. But if you just need to edit one important document, you could use the 7-day trial (watermark-free) and cancel.
How to Choose the Right App for Your Situation
You just need to sign a document
Use Adobe Acrobat Reader. The signature has a legal certificate, it’s completely free, and the interface guides you through it. Takes about 30 seconds total. For more signing options, see our guide on how to sign PDFs for free.
You need to fill out a form
Adobe Reader for forms with clear fields. Xodo if the form is a flat PDF where you need to type on blank lines manually.
You need to annotate for review
Xodo, hands down. The annotation tools are fast, the highlight colors are customizable, and you can export annotated PDFs with comments intact. Your coworkers using Adobe on desktop will see all your annotations correctly.
You need to actually change text content
Foxit (7-day trial for watermark-free), PDFelement (unlimited but watermarked), or the Google Docs conversion method if formatting doesn’t matter.
You need to do it once and never again
iLovePDF web version. No install, no storage used, one free task, done.
Tips for Better PDF Editing on Android
A few things I learned from a month of testing that save time:
Use a stylus for signatures. Finger-drawn signatures look terrible on every app. Even a cheap $15 capacitive stylus produces dramatically better results. Samsung S Pen owners have a big advantage here.
Work in landscape mode. PDF pages are portrait, but your editing toolbar takes up vertical space. Flipping to landscape gives you more room to see the page and tools simultaneously on most apps.
Save to cloud, not local. I lost an edited PDF once because Android’s file system moved it to a temporary cache that got cleared. Always save to Google Drive or another cloud service directly from the app. Xodo and Adobe both support this natively.
Check the output on desktop. Some annotations that look perfect on your phone screen render differently when viewed on desktop software. Before sending an important edited PDF to someone else, open it on your computer or in a web viewer to confirm everything looks right.
For multi-page edits, use a tablet. Editing more than 2-3 pages of a PDF on a phone screen is painful. If you have a Samsung tablet or any Android tablet, the experience is significantly better. Same apps, same features, just more screen real estate.
What About Completely Free and Open-Source?
There’s a gap in the Android ecosystem here. On desktop, tools like LibreOffice Draw can edit PDFs well. On Android, the open-source options are limited to basic viewers. MuPDF is open-source and fast, but it only reads PDFs – no editing. Document Viewer (based on MuPDF) is the same story.
The closest thing to an open-source PDF editor on Android is using Collabora Office (LibreOffice for mobile), which can open and edit PDFs via conversion to its ODF format. But the conversion quality is poor, and the app hasn’t been updated consistently.
For now, Xodo’s free tier is the most generous option that doesn’t put you through a painfully limited open-source experience.
Frequently Asked Questions
Can I edit PDF text directly on Android without a subscription?
PDFelement lets you edit text directly for free, but adds a watermark to saved files. Foxit PDF Editor gives you 7 days of watermark-free text editing. After that, you’d need their $9.99/year plan – the cheapest paid option available.
Is Google Docs good enough for editing PDFs on Android?
For simple text-only PDFs (letters, basic reports), Google Docs conversion works well and costs nothing. For anything with tables, images, or specific formatting, the conversion will break the layout and you’ll spend more time fixing it than starting from scratch.
Which app is best for signing PDFs on Android?
Adobe Acrobat Reader. It’s free, produces legally valid digital signatures with tamper-evident certificates, and the signing workflow takes under a minute. Xodo and iLovePDF also offer free e-signatures but without the Adobe Sign certificate.
Can I edit a scanned PDF on Android?
You need OCR (optical character recognition) first. Adobe Acrobat Pro ($12.99/mo) and PDFelement both offer on-device OCR. For a free option, upload the scanned PDF to Google Drive – it automatically OCRs the text, making it searchable and copy-able, though not directly editable in place.
What’s the maximum file size for free PDF editing on Android?
Xodo handles files up to 500MB without issues. Adobe Reader is similar. iLovePDF caps free uploads at 100MB. SmallPDF limits free files to 50MB. For most documents (contracts, forms, reports), you’ll rarely hit even the lowest limit – a typical 50-page PDF is under 5MB.
