Try PDFTools Free →Most PDF editors require uploading your files to their servers. PDFTools processes everything in your browser. Your sensitive documents never leave your computer. This is a fundamental privacy advantage.
No free trial, no credit card, no "2 free files per day" limit. All basic tools are completely free with a 10MB file limit. Premium removes limits and ads for users who want more.
Compress, merge, split, convert, edit, sign, protect, unlock, and now chat with PDFs using AI. Everything on one site — no jumping between different tools.
Once loaded, the PDF processing libraries run entirely in your browser. No ongoing server connection needed. This means faster processing and true offline capability for installed users.
Adobe Acrobat Pro costs ~$25/month. SmallPDF Premium is ~$12/month. iLovePDF Premium is ~$7/month. If you need basic PDF editing (compress, merge, split, rotate, convert), free tools like PDFTools handle 90% of use cases with zero cost. Only consider paid if you need advanced features like OCR, PDF/A conversion, or very large file support.
No uploads, no signup, 100% private. Start editing your PDFs instantly.
