Crop / resize PDF pages
Trim PDF margins or rescale pages to a standard size.
Crop / resize PDF pages either trims an equal margin off every edge of every page, or rescales each page to fit a standard A4/Letter size while keeping its aspect ratio and centering it.

How to use
- Upload a PDF, then choose "Crop margins" or "Resize to standard size".
- Cropping trims an equal margin from every edge of every page.
- Resizing scales each page to fit within the target size (keeping its aspect ratio) and centers it.
Common use scenarios
- Trimming excess white border from a scanned document before printing or sharing.
- Standardizing a PDF built from mixed page sizes onto one consistent size.
- Preparing a PDF for a printer or binder that expects a specific page size.
- Removing a printer's registration marks or bleed area from a page's edges.

How we verify Crop / resize PDF pages
How to confirm cropping or resizing gave you the result you wanted.
Cropping trims the visible area, not the content
Cropping adjusts the page's visible boundary (its CropBox) — content outside the new boundary isn't permanently deleted, just no longer shown by compliant viewers.
Resizing scales and centers, preserving aspect ratio
When resizing to A4/Letter, each page is scaled uniformly to fit within the target size and centered — it's never stretched or distorted to fill the target exactly.
The two modes solve different problems
Use cropping to trim margins from an already-correctly-sized document; use resizing when the pages themselves need to become a different physical size.
Before you rely on the result
- You've picked the right mode — crop margins vs. resize to a standard size.
- For cropping, you've chosen a margin amount that doesn't cut into real content.
- For resizing, you've picked the correct target size and orientation.
Who this is for
- Anyone trimming excess white border from a scanned document.
- People standardizing a PDF's page size before printing or binding.
- Anyone preparing a document for a specific paper size requirement.
Real-world examples
Trimming a scanned document's border
A flatbed scan comes out with a wide white margin around the actual page content — cropping trims it down to a tighter, cleaner page.
Standardizing mixed page sizes
A PDF assembled from several sources has pages of slightly different sizes — resizing every page to A4 makes the whole document consistent for binding.
Limitations
- Cropping only adjusts the visible page boundary (CropBox) — it doesn't permanently delete content outside it.
Frequently asked questions
Does cropping permanently delete the trimmed-off content?
No — it adjusts the page's visible boundary; the underlying content outside that boundary isn't shown but isn't necessarily deleted from the file structure.
Will resizing distort or stretch my pages?
No — pages are scaled uniformly (same ratio on both axes) to fit the target size, then centered, so proportions are always preserved.
Can I crop different margins on different pages?
No — the same margin amount is applied to every page in one run.
