PDF & Documents
Merge, split, compress and convert files without uploading them. 20 free tools, each one showing the math behind its answer and running entirely in your browser.
Document pages open, change and reassemble a file entirely inside the browser: merge, split, rotate, reorder, add page numbers or a watermark, compress, unlock, turn pictures into a PDF, a PDF into a Word file, and a picture into text.
Nothing is uploaded, so the same page works on a lease as on a shopping list, and it keeps working with the connection off once it has been opened. That is also why there is no queue and no account: the machine holding the file is the machine doing the work.
The limits are stated on each page: what a scan cannot be turned back into selectable text, what compression cannot promise to keep, and which conversions are re-encodings rather than exact copies.
