Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To crop a PDF, add one file, set a crop box on the page or run the auto-trim pass to cut wide margins, then export the updated PDF. Because the tool works in your browser, the document stays on your device and is never sent to a server.
You can apply the same crop to a single page or to every page at once, which makes it quick to tighten a whole scanned document or slide deck in one move.
Many PDFs are structurally fine but framed badly — scan margins are too wide, page whitespace is distracting, or the printable area feels awkward. Cropping fixes the framing without opening a heavier editor or re-laying-out the document.
A focused crop tool keeps that task short: trim the page boxes, check the result, and export. It is the fastest path when the only problem is the visible frame around your content.
Yes. The manual crop path is built around PDF page boxes where possible, so the export stays a real PDF rather than a set of rasterized page images. That keeps the file lighter and the text crisp.
Because no upload is involved, cropping confidential contracts, statements, or scans is safe — the entire operation runs locally in your browser.
Short answers for the questions people usually have before trying a utility like this.
Yes. Cropping PDF pages and trimming margins is free, with no account or watermark.
No. This tool crops PDFs entirely in your browser, so the file stays on your device and is never uploaded to a server.
No. The manual crop path is built around PDF page boxes where possible, so the exported file stays a real PDF with selectable text.
Yes. The tool supports both current-page and all-pages apply modes, so you can crop one page or the whole document at once.
Yes. An auto-trim pass detects and removes obvious whitespace margins, which you can then fine-tune with the manual crop box.
