Crop PDF Securely
Crop PDF securely with ContinuePDF's client-side tool, built so your data never travels across the network in the first place.

By running the crop operation on your device, ContinuePDF removes the server from the equation entirely.

What you can do with Crop PDF
Cropping trims the visible area of PDF pages — cutting away excess margins, borders, or scan edges — so the content sits cleanly, without altering the text itself.
Remove scan borders
Cut the black edges or shadow a scanner leaves around a page.
Tighten wide margins
Trim oversized margins so more content fits on screen or prints larger.
Focus on one area
Crop each page down to a table, figure, or receipt when the rest of the page is not needed.
Standardise page size
Even out inconsistent margins across pages that came from different sources.
A more secure model for Crop PDF
The weakest point in most online PDF workflows is the round trip to a server: the upload can be intercepted, the server can be compromised, and copies can linger in logs, caches, or backups long after you are done. Adding TLS helps in transit, but it doesn't protect the copy that ends up sitting on the provider's disk.
ContinuePDF's approach is to not send the file anywhere. The crop logic runs inside your browser's sandbox, isolated from other sites and from the wider system. Your PDF exists only in your device's memory while the tool works, which shrinks the attack surface to essentially zero — there is no server component to breach.
Why choose ContinuePDF
No transmission
The file is never sent over the network, so it can't be intercepted.
No retention
Nothing is stored server-side — no logs, caches, or backups of your file.
Sandboxed
Processing runs inside the browser's isolated security sandbox.
Minimal surface
No server component means there is nothing on our side to attack.
Pro tip
Crop conservatively and preview before downloading — it is easy to cut into text or a signature line near the edge. If pages have different margins, adjust the crop per page rather than applying one box to everything.
Frequently asked questions
Does cropping delete the content outside the crop area?
Cropping trims the area outside the box so it no longer shows or prints. Because that region is removed from the visible page, crop with a little margin to avoid cutting anything important.
Can I apply the same crop to every page?
Yes. You can crop all pages to the same dimensions for a consistent look, or adjust individual pages when their margins differ.
How is this more secure than other Crop PDF tools?
Most tools upload your file to a server, creating a copy that can be intercepted, logged, or breached. ContinuePDF processes your PDF inside your browser, so the document is never transmitted and no server-side copy is ever created.
Are my files stored anywhere after I crop them?
No. Because the file never leaves your device, there is nothing stored on our end. The document lives only in your browser's memory during processing and is cleared when you close the tab.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Crop PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
