How does trimming white margins work?

Each page is looked at as it appears, and the crop is drawn round everything that is not white, with a few millimetres to spare. Pages that are the same size are all cropped to the same box, so the document keeps one page size and nothing on one page is cut off where another page has content. Blank pages are left as they are.

My margins are not white. What should I use?

Choose Trim a set amount and pick how many millimetres to cut off each side, from 1 to 50. That works for a dark scanner border, a coloured background, or printer's marks round the edge.

Is the content outside the crop deleted?

No. Like cropping in Acrobat, this sets the part of each page that is shown and printed; what is outside it is still in the file, and some programs can show it again. Do not rely on cropping to remove anything confidential.

Will the text still be selectable?

Yes. The pages are not turned into pictures, so text stays selectable and searchable, drawings stay sharp, and images keep their resolution. The file comes out about the same size.

Can I crop only some pages?

Yes. Leave the Pages field blank to crop the whole document, or name the pages, such as 1-3 or 1,3,7. Pages you do not name are left exactly as they were.

Is this converter free?

Yes. Every conversion on ConvertNicely is free to use, with no account and no watermark on the result. Everyone can run 50 jobs and upload 2 GB a day, with or without an account.

What happens to my files?

Your uploaded file is deleted from our servers the moment the conversion finishes, whether it succeeded or failed. The converted result is deleted automatically one hour later, and you can delete it yourself at any time with the Delete button.

Is there a file size limit?

Files up to 95 MB are accepted for this conversion. Larger limits apply to paid plans in future, but the free limit is generous enough for the overwhelming majority of PDF conversions.

Do I need to install anything?

No. ConvertNicely runs entirely in your browser and on our servers, so there is nothing to download or install. It works the same on Windows, macOS, Linux, Android and iOS.

Does it work on a phone?

Yes. The whole site is built mobile-first, so you can upload from your camera roll or files app, convert, and download the result without leaving your browser.

Crop PDF Pages

Wide white margins make a PDF hard to read on a phone or e-reader, and leave a figure floating in empty space when you drop it into a slide. This finds the content on each page and crops close round it, keeping every page the same size, or trims the same distance off every side if you prefer. Nothing is re-rendered: text stays selectable and the file stays the same size.

Worth knowing

Cropping hides the margins rather than deleting them: what was outside the crop is still in the file and some programs can show it again, so do not use it to remove anything confidential. Password-protected PDFs are refused; Unlock PDF removes the password first (a PDF that only restricts printing or copying unlocks without one).

Why crop PDF pages?
