Open toolWhy 'no upload' matters
Most popular PDF sites upload your file to their servers to process it. For invoices, contracts, IDs, and medical records, that means handing a copy of sensitive data to a third party. Browser-based tools process the file on your own device, so the document never leaves your computer — the strongest privacy guarantee there is.
Everything you can do in the browser
Merge PDF — combine multiple files into one, in any order.
Split PDF — extract pages or separate a document into parts.
Compress PDF — shrink file size for email and upload limits.
Rotate, add page numbers, watermark, extract and remove pages.
Convert PDF to JPG, and JPG to PDF — without sending anything to a server.
Free, with no catches
Every tool is completely free: no watermarks, no file-size paywall, and no sign-up required. You can create a free account if you want your history and favorites saved, but you never have to.
