Trim PDF margins and resize pages visually
A crop PDF tool lets you trim the visible area of every page in a PDF document — removing excess margins, cutting out unwanted borders, or focusing on a specific region of each page. pdfEditor lets you crop PDF free by drawing a visual rectangle directly on a preview of your page, right in your browser. There is nothing to install and nothing to sign up for.
Because this is a genuinely free PDF page trimmer, there are no daily task limits, no watermarks stamped onto your output, and no "upgrade to Pro" paywall. You can crop as many documents as you like, as often as you need.
Why crop a PDF?
People need to trim PDF margins for all sorts of everyday reasons: removing the excessive white borders that scanned documents often have, fitting a slide deck to a different aspect ratio, cropping a receipt to show only the relevant transaction, or adjusting the visible area of a book page for e-reader display. Cropping keeps the content you want and hides the rest, making the document more focused and professional.
Doing this online without an account matters when the document is sensitive. A legal filing or financial report should not have to be uploaded to someone else's server just to have its margins trimmed. With a client-side tool you get to crop PDF pages free while keeping the file on your own device.
How to crop a PDF free online
- Upload your PDF. Drag and drop the file into the upload area above, or click to browse and select it.
- Draw the crop area. Click and drag on the page preview to select the rectangle you want to keep. The dimmed regions outside will be trimmed away.
- Crop and download. Click "Apply Crop" and your browser applies the selection to every page, producing a trimmed PDF ready to download.
That is the entire process to crop PDF online — no email address, no server processing, and no queue.
Frequently asked questions about cropping PDFs
Is this crop PDF tool really free? Yes. It is a crop PDF free tool with no hidden tier — no signup, no subscription, and no per-day cap on how many documents you can crop.
Can I crop a PDF without login? Absolutely. There is no login of any kind. You open the page and start working immediately, which is exactly what people searching for resize PDF page online are looking for.
Will the crop change the file size? The CropBox approach typically does not change the file size significantly, since the original content remains in the file (just hidden from view). If you need to reduce file size, use the Compress PDF tool afterward.
Does the crop affect text selection and search? Content outside the crop area is hidden from view but may still be accessible via text search or copy-paste in some PDF readers. If you need to permanently remove content, a different approach may be needed.
Private by design
Every crop operation happens entirely in your browser using JavaScript — your files are never uploaded to a server, stored, or transmitted anywhere. The moment you close the tab, nothing remains. That is what makes this a safe way to adjust PDF page size online: the privacy is inherent in the architecture, not just a policy promise.
Tips for precise cropping
For the most accurate crop, zoom in on the preview page by maximizing your browser window before drawing the rectangle. The crop area snaps to the exact pixel positions you select, so a larger preview gives you finer control over the boundaries.
If your document has different content areas on different pages, consider splitting it into groups of similar pages first using the Split PDF tool, cropping each group separately, and then merging the results. Since every tool runs locally, there is no upload overhead between steps.
