Adobe Acrobat Pro is $19.99/mo. Smallpdf is $9/mo. iLovePDF is $7/mo. All three upload your PDF to a server before they touch it. Most users only need three things: fill a form, merge two documents, sign a contract, sometimes redact something. None of that needs a cloud round-trip.
We tested seven offline PDF editor apps for Android against the workflow that breaks free apps: editing a 200-page document with stamped text, signing a one-page PDF on the train without signal, and merging a few scans into a single file. All seven do the editing on-device. We ranked them by how much you can do before the upsell or the watermark.
What to look for in an offline PDF editor app
Most PDF apps advertise “offline” but route the heavy work to a server. Watch for these.
- Real on-device editing. If the app says “Processing” and shows a progress bar that needs internet, it is not offline.
- Form filling and signing. Free apps often gate signature placement behind a paywall.
- Annotation export. Highlights and notes should save into the PDF, not into a sidecar file only the app can read.
- Page operations. Reorder, split, merge, rotate, and delete should be free at minimum.
- No silent watermark. Some apps drop a “Made with X” footer on save without warning.

The apps
1. Xodo, best for most users
Xodo is the answer to “what should I install” 90% of the time. Editing text, adding signatures, filling forms, reordering pages, merging, splitting, and exporting are all on the free tier with no watermark. The interface is cleaner than Foxit’s and faster than Adobe’s. After Apryse acquired it, the editor got significantly better in 2024, and the team kept the free tier intact.
Xodo for offline PDF editor work is the closest thing to “Acrobat without the subscription”. It handles 200+ page documents without slowing down and the text-edit tool is the best on Android short of paying Adobe.
Where it falls short: Banner ads on the free tier are mildly annoying. Some advanced features (OCR on scanned PDFs, password encryption) require Xodo Pro.
Pricing:
- Free: editing, signing, annotation, form fill, page operations, ads
- Pro: about $9.99/mo or $59.99/year for OCR, encryption, ad removal
Platforms: Android, iOS, Web, Windows, Chrome extension
Bottom line: Xodo is the offline PDF editor app to install first. Most people never need anything else.
2. Foxit PDF Editor, best for pro features and a fast viewer
Foxit PDF Editor is the Acrobat alternative the enterprise IT world has used for a decade. The viewer is the fastest of anything on this list (huge architectural drawings open in seconds), and the desktop apps share the same file format and feature set as the mobile editor. Form-filling and signature placement are first-class.
Foxit for offline PDF editor needs earns its place at the high end. Heavy users who deal with 500-page documents, multi-layer redaction, or cross-platform PDF workflow get more value here than from a casual editor.
Where it falls short: The free tier on mobile is mostly a reader. Real editing needs the Editor subscription. The UI also has more menus than necessary, which adds friction for one-off tasks.
Pricing:
- Free: reader, basic annotation
- Editor: about $9.99/mo or $99.99/year, includes desktop and mobile
Platforms: Android, iOS, Windows, Mac
Bottom line: Foxit is for people who edit PDFs daily and want desktop and mobile parity. Casual users should skip.
3. PDFelement, best for cross-device PDF projects
PDFelement from Wondershare is the closest to Acrobat in feature parity. Edit text and images, add interactive form fields, redact, OCR, and use the AI assistant if you want it. The mobile and desktop apps sync through Wondershare Cloud or your own Dropbox, which keeps a project usable on the train and the laptop.
PDFelement for offline PDF editor projects is solid because the mobile app can save locally even when the cloud is off. The free tier on mobile is more limited than Xodo’s, but the editor is closer to desktop Acrobat than anything else.
Where it falls short: Pricing is one of the higher in this list, the free tier watermarks edited exports, and the upsell modals are frequent. The “AI assistant” is paywalled and not the reason to buy this.
Pricing:
- Free: viewer with limited editing and watermark on save
- Standard: about $79.99/year
- Pro: about $129/year for OCR, redaction, batch processing
Platforms: Android, iOS, Windows, Mac
Bottom line: PDFelement makes sense if you already pay for the desktop version. Standalone mobile users should pick Xodo first.
4. KDAN PDF Reader, best for detailed annotation tools
KDAN PDF Reader is the most polished annotation tool on Android. Brush, highlighter, sticky note, stamp, and rectangle markup feel closer to a tablet PDF reader than to a mobile app. Pen input is responsive, and the export bundles all annotations into the file, not into a sidecar.
KDAN for offline PDF editor reading is the right pick if you mark up documents on a tablet with a stylus. The Document 365 ecosystem is overkill for casual users, but students and lawyers who read on a tablet get real value.
Where it falls short: Text-content editing is weaker than Xodo or Foxit. The pricing has too many tiers (Reader, Document 365, Creative). The free tier is essentially a reader.
Pricing:
- Free: reader, annotation, basic markup
- Pro: about $4.99/mo or $44.99/year for editing, OCR, conversion
Platforms: Android, iOS, Windows, Mac
Bottom line: KDAN is for tablet users who annotate by hand. Skip on a phone.
5. WPS Office, best all-in-one Office and PDF
WPS Office is one app for documents, spreadsheets, presentations, and PDFs. The PDF editor sits inside the same toolset as the Word, Excel, and PowerPoint replacements, which makes sense if you switch between formats often. The free tier handles editing, signing, merging, and conversion offline.
WPS Office for offline PDF editor needs is the pick if you already use it for documents. The PDF tools are good but not best-in-class; the value is in not switching apps.
Where it falls short: The free tier shows ads, including occasional full-screen interstitials between tasks. Some PDF features (OCR on scans, batch conversion) need the Premium tier.
Pricing:
- Free: most editing and conversion, ads
- Premium: about $35.99/year for ad removal, AI, advanced PDF tools
Platforms: Android, iOS, Windows, Mac, Linux, Web
Bottom line: WPS Office is the right install if you also need Word, Excel, and PowerPoint replacements. Otherwise it is overkill for PDFs alone.
6. Adobe Acrobat Reader, best for fillable forms and signatures
Adobe Acrobat Reader is, perhaps surprisingly, the best free option for forms and signatures specifically. Fillable forms work natively because Adobe defines the format, signatures place correctly with no quirks, and form data saves into the PDF cleanly. The free tier covers reading, basic commenting, form filling, and signing.
Adobe Reader for offline PDF editor signatures is the path of least resistance. Government forms, tax PDFs, and bank documents are usually authored for Acrobat, so behaviour is identical to the desktop version.
Where it falls short: Real editing (changing existing text, adding pages, merging) needs the paid Acrobat Premium tier, and the upsell is aggressive. The free tier nags about Premium on most actions beyond reading.
Pricing:
- Free: read, fill forms, sign, annotate
- Premium: about $9.99/mo for edit, export to Word, merge
- Pro DC: about $19.99/mo for full feature parity with desktop
Platforms: Android, iOS, Windows, Mac, Web
Bottom line: Keep Adobe Acrobat Reader for the form-and-sign use case. Use Xodo for everything else.
7. PDF Viewer (Digi Work), best lightweight free reader
PDF Viewer is a small, fast, ad-light reader for people who only need to view and lightly annotate. Open speed is the fastest in this category for documents under 50 pages, the app is under 30MB, and there is no account or upsell.
PDF Viewer for offline PDF editor reading is the pick when you do not want a full editor. It will not edit text, fill complex forms, or merge documents, but it opens a PDF the moment you tap.
Where it falls short: No editing. No real form support. Limited annotation. Anything beyond viewing and basic highlights needs another app on this list.
Pricing:
- Free, no in-app purchases
Platforms: Android
Bottom line: PDF Viewer is the install if “offline PDF editor” is overkill and you just need to open documents fast.
How to pick the right one
We have lived with each of these for at least a couple of months. Pick by what you actually do with PDFs.
- If you want one app that handles 90% of PDF tasks, install Xodo. It is the most generous free tier in this list.
- If you fill government forms, tax PDFs, or sign contracts, keep Adobe Acrobat Reader alongside Xodo. Behaviour matches what the form authors intended.
- If you mark up papers or contracts on a tablet with a stylus, KDAN PDF Reader has the best annotation feel.
- If you already use a Microsoft Office replacement, WPS Office removes one app from your dock.
- If you edit text inside complex PDFs daily (legal, publishing, technical), Foxit PDF Editor or PDFelement justify their subscription.
- If you only need to open a PDF and never touch it, PDF Viewer is the lightest install.
