Adobe Acrobat costs $24.99/month. But in 2026, you can edit, compress, merge and sign PDFs completely for free — right in your browser. We tested the top options and ranked them on what actually matters: whether they're genuinely free, what features you get without paying, and whether they put a watermark on your file.
The 5 Best Free PDF Editors (Ranked)
Fourmeld PDF Tools
Fourmeld offers a full browser-based PDF toolkit — edit text, add annotations, compress, merge, split, rotate, and convert — all free, with no watermark and no account required. Everything runs in your browser, so your files are never uploaded to a server.
- Completely free, no limits
- No watermark ever
- No login required
- Works in browser — private
- Compress, merge, split, rotate, annotate
- No OCR (searchable PDF) yet
PDF24 Tools
PDF24 is a solid free option with a wide range of tools — convert, compress, merge, sign, edit. It's free and doesn't add watermarks. However, it's slower and the interface is less polished. Processing happens on their servers, so large files can be slow.
- Many tools available
- No watermark
- Free desktop app available
- Slower processing
- UI feels dated
- Files uploaded to their server
Smallpdf
Smallpdf is popular and well-designed but its free plan is very limited — you can process 2 files per hour. After that, you must wait or pay $12/month. It's fine for very occasional use but frustrating for regular tasks.
- Clean, easy interface
- Many tool types
- Only 2 files/hour free
- Requires account for some features
- Expensive paid plan
iLovePDF
iLovePDF offers good free tools for merging, splitting, compressing and converting PDFs. The free tier has file size limits (max 200MB) and ads but no watermark. Useful for basic tasks.
- No watermark on free plan
- Good range of tools
- Mobile app available
- File size limits on free plan
- Ads on free plan
- Signup required for some features
Sejda
Sejda is a capable PDF editor with a clean UI. Free plan allows 3 tasks per hour, max 200 pages and 50MB per file. Good for editing text directly in PDFs, which is rare in free tools.
- Can edit text directly in PDF
- Clean interface
- No watermark
- 3 tasks per hour limit
- 50MB file size limit
- Slow free tier
Verdict
For a genuinely unlimited, no-watermark, no-login PDF editor — Fourmeld is the clear winner. PDF24 is a solid second choice for desktop users. Smallpdf and iLovePDF are fine for very occasional use but hit paywalls quickly.
