PDF24 has been around since 2006 and has strong brand recognition in DACH markets.
Frequently asked questions
Is PDFree really free, like PDF24?
Yes. PDFree is free with no credit card required. The free plan includes 10 operations per day across all 18 tools, with no watermark on output and no account requirement. PDF24 is also free, but its desktop client requires a Windows install and the online version uploads every file to its server.
Does PDFree offer a desktop app like PDF24?
No. PDFree is browser-only by design. For tools like rotate, sign, redact, watermark, and crop, processing happens entirely in your browser via WebAssembly — files never leave your device. This is faster than installing a desktop app and works on any operating system.
Which is more private, PDFree or PDF24?
PDFree's client-side tools are more private: files are processed in browser memory and never uploaded. PDF24's online tools always upload to its servers. PDF24's desktop client is local but requires a Windows install. PDFree's server-side tools (compress, merge, split, protect, unlock) delete files from memory immediately after processing.
Can PDFree handle large PDF files?
PDFree client-side tools accept files up to 200 MB. Server-side tools accept up to 50 MB on the free plan. PDF24 has higher limits on its desktop app but lower limits on its free online version.
