Trim margins from every page with live preview. 100% free, no sign-up — your file never leaves this browser tab.
Crop PDF lets you crop a PDF entirely inside your browser, with no software to install and no account to create. Like every tool on Techsinghge Smart Tools, it's built around adding a finishing touch to a document — text, numbers, images, or metadata, and it works the same way whether you're on a laptop, a Chromebook, or a phone.
Under the hood, Crop PDF takes one PDF file and hands back a PDF with trimmed page margins. Your file is loaded directly into this page's memory using JavaScript — nothing is transmitted to a server, which means there's no upload wait, no file-size cap tied to a paid plan, and no copy of your document left sitting on someone else's storage once you're done.
Removing wide white margins from a scanned document is one of the most common reasons people reach for this tool, but it works just as well for trimming a PDF down to just its content area before printing. If you need a related step before or after this one, check the related tools further down the page — every tool on this site is designed to slot into the same drag-and-drop workflow.
No installs, no accounts — just your browser doing the work.
Scroll up (or tap “Use Crop PDF now”) to load the tool instantly — no account or install needed.
Drag and drop one PDF file into the drop zone below, or click it to browse your device.
Adjust whatever settings this tool offers so the result comes out exactly how you want it — sensible defaults are already selected.
Click Run, then download a PDF with trimmed page margins straight to your device — it's generated locally and ready in seconds.
See exactly what will be trimmed before you commit, using an on-page preview.
Set the crop area once and apply it consistently across the whole document.
Your one PDF file stays on this device the whole time — nothing is uploaded, logged, or stored on a server.
Processing happens right in this browser tab, so there's no upload progress bar, no server queue, and no processing fee.
Because Crop PDF runs locally, teams handling sensitive paperwork — legal, HR, healthcare admin, finance — can use it without the compliance questions that come with uploading documents to a third-party server. And if you only need it for a single one-off task, it's just as useful with zero setup and nothing to remember to delete afterwards.
The crop area is applied uniformly across all pages for consistency; for page-specific edits, process a page range separately.
Cropping produces a new file, so your original PDF is left untouched and can be re-processed anytime.
