PDF Tools
Trim PDF
Remove a fixed number of pages from the start and end of a PDF — the cover sheet, the terms page, the blank the scanner added. Say how many to cut from each end and the tool shows exactly what survives before you download. Everything happens on your device.

Frequently asked questions
Are my files uploaded to a server?
No. Everything happens locally in your browser using JavaScript and WebAssembly. Your files never leave your device, nothing is stored, and the tool even keeps working if you go offline after the page loads. That makes it safe for contracts, IDs, medical records and other sensitive documents.
How is trimming different from cropping?
Trimming removes whole pages; cropping changes the shape of the pages you keep. If a scanner left a grey border down every page you want Crop PDF. If the document opens with a cover sheet you never asked for and ends with a blank, this is the tool — the page count goes down, the pages themselves are untouched.
Why not just use the Split tool?
Split asks which pages you want and gives you those. That is the right shape when you are pulling three pages out of forty. Trimming is the opposite: you want almost all of it, minus a couple at each end, and working out that the answer is “2-39” is arithmetic the tool should do for you, not the other way round.
Does trimming reduce the file size?
Usually a little, because the removed pages and anything only they referenced are not carried into the new file. It is not a compression tool though — if the goal is a smaller file rather than fewer pages, compress the PDF instead, which works on the images and fonts inside it.
