Crop a PDF
Trim the margins off every page — as a percentage, so it works on pages of different sizes.
Runs in your browser. Nothing is uploaded.
Scanned pages come with borders nobody wants, slide decks come with margins that waste half a tablet screen, and a page printed from a browser comes with a header and a footer. Cropping is how those go away, and the first page is shown large with the kept region outlined so the setting is something you look at rather than something you calculate.
The edges are percentages rather than millimetres, which is the only thing that works across a document whose pages are not all the same size — a report with a landscape appendix would need two sets of numbers otherwise. Every page is trimmed by the same proportion of its own width and height.
Cropping a PDF is a box, not a knife. The format has a crop box that tells a viewer which part of the page to show, and that is what gets set: the content outside it is still in the file, and a determined reader can put it back. That is worth knowing if you were cropping something out for privacy — for that, the answer is to remove the page, not to hide part of it.

Questions
Is the cropped-off content deleted?
No. A PDF crop sets the box a viewer displays; everything outside it is still in the file. Do not use it to hide sensitive material.
Can I crop each page differently?
No — one setting applies to every page, as a proportion of each page. That is what makes it work on a document of mixed sizes.
Will the text still be selectable?
Yes. Nothing is rasterised, so the page is the same text it was, shown through a smaller window.
