Is my PDF uploaded to a server?

No. Cropping happens in your browser with pdf-lib — your file never leaves your device, and there's no watermark or signup.

Does it crop every page the same way?

Yes. Margins are set as a percentage, so the same crop adapts to each page and applies to the whole document.

Is the cropped content deleted?

No — cropping changes the visible page box, so content outside it is hidden rather than removed. Keep your original if you may need the full page later.

Can it crop a password-protected PDF?

Remove the password first, then crop the unlocked PDF.

Crop PDF

Trim PDF margins with a live preview — drag sliders to crop every page, then download. Runs in your browser, nothing uploaded.

Processed 100% in your browser — nothing you enter here is ever uploaded.

Common use cases

Remove white margins

Trim wide borders so the content fills the page — great for reading on small screens.

Crop scanned pages

Cut off black scan edges or hole-punch marks around a scanned document.

Focus on the content

Keep only the important area of each page for a cleaner, tighter PDF.

How to use the Crop PDF

Drop a PDF into the box, or click to browse. It's processed in your browser — nothing is uploaded.

The first page appears as a preview. Drag the Top, Bottom, Left and Right sliders to trim margins.

The bright area shows exactly what will be kept; the darkened area is cropped away.

Click "Crop & download" to apply the same crop to every page and save the result.
