Below we show how to trim PDF margins online, for free. Works on all desktop platforms including Mac.

1. Upload your files

   Files are safely uploaded over an encrypted connection. Files stay secure. After processing, they are permanently deleted.

   Rather not upload your files and work with them offline?
   Try Sejda Desktop. Same features as the online service, and the files never leave your computer.

   Click 'Upload' and select files from your local computer.

   Dragging and dropping files to the page also works.

   Dropbox or Google Drive files

   You can pick PDF files from Dropbox or Google Drive too.

   Expand the 'Upload' dropdown and select your files.

2. Crop whole document (in one go)

   Pages are rendered on top of each other, blended, so you can easily determine the crop size that matches all pages.

   Only first 30 pages are rendered by default. For larger documents you have the option to render all pages.

3. Crop PDF pages separately

   You can choose to crop only certain pages. Each page can be cropped with a different size.

4. Automatically trim PDF white margins

   We can automatically determine what is the optimal crop size so all white margins are removed.

   Click on 'Auto-crop' right above the page.

5. Specify precise crop margins in inches

   Exact dimensions can be specified for the cropped margins.

   Input the top, left, bottom and right margins above the PDF page.
