Top 10 Free PDF Editor Apps in 2026

Apps • Updated May 2026 • 12 min read

PDF editing on mobile devices has come a long way. A few years ago, you needed a desktop computer to do anything beyond reading a PDF. Now, your phone or tablet can handle most PDF tasks — annotating, filling forms, signing documents, and even editing text.

We tested a range of PDF editor apps on both iOS and Android, and these 10 impressed us the most with their combination of features, ease of use, and value.

Quick Comparison

1. Xodo PDF — Best Overall

Platform: iOS, Android, Web | Price: Free

Xodo has consistently been one of the best free PDF apps available, and 2026 is no exception. It handles annotation, form filling, signing, and basic editing without throwing up a paywall for core features. The interface is clean and intuitive, which is rare for a free PDF tool.

What sets Xodo apart is its reliability. Features that work in some free PDF apps and fail in others — text annotation, bookmark creation, document merging — all work reliably in Xodo. It also syncs with Google Drive, Dropbox, and OneDrive, which is convenient if you work across devices.

What We Liked

• Genuinely useful free tier
• Reliable annotation and form filling
• Cloud storage integration
• Available on both iOS and Android

What Could Be Better

• Text editing is limited
• Interface can feel busy with many toolbars

2. FreeCVT — Best for Quick PDF Conversions

Platform: Browser (works on any mobile device) | Price: Free

Sometimes you don't need to edit a PDF — you need to convert it to something else. FreeCVT's PDF to Word converter handles this directly in your mobile browser, no app installation required. Your file is processed locally, which means it never touches a server — a genuine privacy advantage for sensitive documents.

We tested FreeCVT on both iOS Safari and Android Chrome, and the experience was smooth across both. The tool converts PDF to DOCX while preserving formatting as much as possible, and FreeCVT offers dozens of other PDF tools — PDF to JPG, PDF compression, PDF splitting — all browser-based.

What We Liked

• Works on any device with a browser
• No app installation required
• Files processed locally for privacy
• Multiple PDF tools in one suite

What Could Be Better

• No annotation or form filling tools
• Requires internet connection
• File size limited by browser

3. Adobe Acrobat Reader — Best for Industry Compatibility

Platform: iOS, Android | Price: Free, Pro from $19.99/month

Adobe invented the PDF format, so it makes sense that their reader app remains one of the most capable. The free version handles annotation, form filling, and signing. If your work involves PDFs that were created in Acrobat with complex features, this is the app most likely to display them correctly.

What We Liked

• Best compatibility with complex PDFs
• Industry standard
• Reliable form filling

What Could Be Better

• Free version has limited editing
• Pro subscription is expensive
• Can feel heavy on older devices

4. PDF Expert — Best for iOS

Platform: iOS, Mac | Price: Free, Pro from $7.99/month

PDF Expert is a beautifully designed PDF app for Apple devices. The free version covers reading, annotation, and form filling. The paid version adds text editing and advanced features. If you're fully invested in the Apple ecosystem, PDF Expert feels right at home.

What We Liked

• Beautiful, native iOS design
• Smooth annotation experience
• Good sync between iPhone and Mac

What Could Be Better

• iOS/Mac only
• Text editing requires paid version

5. PDFelement — Best All-Around Editing

Platform: iOS, Android | Price: Free, Pro from $49.99/year

PDFelement offers the most comprehensive editing capabilities of any free PDF app we tested. You can edit text, change images, rearrange pages, and add annotations. The free tier is limited, but even basic access gives you more editing power than most competitors.

What We Liked

• Powerful text editing on mobile
• Page management tools
• Good OCR for scanned documents

What Could Be Better

• Free tier is quite limited
• Can be complex for simple tasks

6-10: Quick Reviews

6. Foxit PDF Reader

A solid business-oriented PDF reader with annotation, signing, and collaboration features. The free version covers most needs, and it's lighter than Adobe's offering. Good choice for professionals who regularly work with PDFs.

7. GoodReader

More of a file manager with PDF capabilities than a dedicated PDF editor, but it handles PDF reading, annotation, and markup exceptionally well. If you need to manage many files alongside PDF editing, GoodReader is worth considering.

8. CamScanner

Specializes in turning paper documents into PDFs using your phone's camera. The scanning quality is impressive, and it handles OCR (text recognition) well. Less useful for editing existing PDFs, but excellent for creating them from paper.

9. SwiftPDF

A lightweight PDF editor for iOS that covers the basics without bloat. Annotation, highlighting, and simple edits work well. If you want something fast and simple, SwiftPDF delivers.

10. Sejda PDF Editor

A browser-based PDF editor that works on any device. The free tier allows 3 tasks per day with files up to 50MB. Good for quick edits when you don't want to install an app.

How We Tested

Each app was tested on both iOS and Android (where available) using a standard set of PDF files:

1. Text document: 5-page text-heavy PDF
2. Form: Fillable PDF form with text fields and checkboxes
3. Scanned document: Image-based PDF requiring OCR
4. Large file: 50MB PDF with images

We evaluated annotation quality, form filling, editing capabilities, and overall reliability.

Frequently Asked Questions

Can I edit a PDF on my phone for free?

Yes. Apps like Xodo and PDFelement offer free editing capabilities on mobile. For text editing specifically, many free apps have limitations — but annotation, form filling, and signing are generally free.

How do I convert a PDF to Word on my phone?

Use a browser-based tool like FreeCVT's PDF to Word converter. Open it in your mobile browser, upload your PDF, and download the DOCX file. No app installation needed.

Are free PDF apps safe for sensitive documents?

It depends on the app. Browser-based tools like FreeCVT that process files locally (without uploading to a server) are safer for sensitive content. If you use a cloud-connected app, check their privacy policy to understand where your files are stored.

What's the best way to sign a PDF on my phone?

Xodo and Adobe Acrobat Reader both offer free electronic signature features. Simply open the PDF, tap the signature tool, draw your signature with your finger, and place it on the document.

Bottom Line

Xodo is the best free PDF editor app for most people — it works on both platforms, handles the essential tasks reliably, and doesn't push you toward a paid subscription. For quick PDF conversions on mobile, FreeCVT is a privacy-friendly option that requires no installation.

Your phone is more capable than you think — these apps prove it.
