Every tool you need to work with PDFs
Merge, split, compress, convert, edit, protect and analyze PDFs with AI — most tools run entirely in your browser, so your files stay private.
Free online PDF tools that respect your privacy
Codesala PDF is a complete, genuinely free toolbox for working with PDF documents — merge and split files, compress oversized scans, convert images and Word documents, edit text directly on the page, add watermarks and page numbers, protect files with real AES encryption, and analyze documents with AI. What makes it different is where the work happens: most tools process your files entirely inside your browser, so contracts, statements, medical records and ID scans never leave your device. No accounts, no watermarks, no upsells — every tool is fully unlocked for everyone.
Every PDF task, one place
Need to combine PDFs into one file, shrink a PDF for email, turn photos into a PDF, or fix a typo in a final document? Each tool has its own focused page that does one job fast, with drag & drop, instant downloads and no learning curve. On mobile it works just as well — convert, organize and share documents straight from your phone.
