Redact
Cover confidential text and images with boxes or a brush. On export every page is rasterised, so the covered content is permanently removed and cannot be recovered.

All processing happens locally in your browser. Your files are never uploaded to any server.
Trim the edges of every PDF page by setting a margin in millimetres on each side - handy for removing scanner borders, standardising page margins across a document, or cutting away headers and footers you do not need.
Cropping only changes the visible area and never reflows the content; everything runs in your browser with no uploads, and you can re-try with different margins until it looks right.
How to use it
- Add a PDF.
- Enter the crop amounts in mm for top, bottom, left and right.
- Click Start and download the cropped PDF.
Frequently asked questions
- Does cropping delete edge content?
- Cropping changes the visible boundary of each page; content is not reflowed, so anything in the cropped area simply stops being shown.
- Are all pages cropped the same way?
- Yes - the margins you enter apply to every page, which is ideal for standardising layout.
- Are my files uploaded to a server?
- No. Everything runs in your browser and there is no upload endpoint, so the server never sees your content.
- How large a file can I use?
- Stay under about 100 MB and a few thousand pages. Speed and memory depend on your own device.
- Is it free? Do I need an account?
- It is completely free with no usage limit, and no sign-up or login is required.
- Does it work on phones?
- Yes, the layout is responsive. Large files and complex edits are easier on a desktop.
- Which browsers are supported?
- Any modern browser: Chrome, Edge, Firefox, Safari and their mobile versions.
- Does it work with scanned PDFs?
- Yes for page-level operations, which do not need a text layer. There is no OCR, so text cannot be pulled out of a scan.
