About this tool
This tool does one job and does it entirely on your device. Crop PDF pages by margins — vector crop, no re-rendering. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Practical limits apply (files up to 10MB), and it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; File limits: files up to 10MB; Privacy: the file never leaves the device.

FAQ
Will my file be uploaded?
No. Everything runs locally in your browser — your file is never uploaded and is cleared upon closing the page.
Are there any limits?
Cropping is configured by margins, with bleed expansion written to the CropBox and clamped within MediaBox; files must be ≤ 10MB.
Will my original file be modified?
No. The tool reads your file and produces a new one — the original stays untouched.
Can I process multiple files in bulk?
A single tool page handles one task at a time; for bulk work use the Batch Processing workflow and add this tool as a step to run a whole set at once.
Is the processed file still editable?
The output is a newly cropped PDF; the original file remains untouched and you can continue editing or readjusting it with other tools.
