Why “no upload” matters
Because every tool runs entirely inside your browser, your files are never uploaded to a server. They’re processed on your own device and never leave it — a real difference for anyone handling contracts, IDs, medical records or anything confidential.
It also makes the tools fast — there’s no waiting to upload a large file and download it back. Your document is ready the moment processing finishes.
Everything you can do — free and private
pdfcdf covers the everyday essentials: merge and split PDFs, delete or reorder pages, rotate, crop and resize, add page numbers or a watermark, sign documents and fill forms, run OCR on scans, and convert between PDF and images. There’s no account, no watermark on your output, and no daily limit.
