A free PDF crop tool that automatically trims white margins around the content. Works on CAD exports, vector drawings, scanned PDFs and multi-page documents - all in your browser. Your files are never uploaded.
If you've ever exported a drawing from AutoCAD, ArchiCAD, Revit or any other CAD package, you know how much white space ends up on the page. This tool removes that extra space automatically, leaving you with a clean, content-only PDF that's ready to share or print.
Unlike most "PDF crop online" services, Docuex's tool runs entirely in your browser using the PDF stream itself. We never upload your files anywhere - they stay on your computer from start to finish. That makes it suitable for confidential drawings, signed documents, intellectual property and anything else you'd rather not hand over to a third-party server.
The tool analyses each page of your PDF, finds the bounding box of the actual content (lines, text, shapes), and rewrites the page's crop box to that bounding rectangle plus the margin you choose. The underlying drawing data isn't changed, only what's visible. This means file size stays similar, vector quality is preserved, and the cropped PDF works in every CAD and DTP tool.
Architects and engineers use it to tidy CAD exports before sending to clients. Estate agents and property managers use it to remove white borders from listing brochures. Print shops use it to save paper on big drawings. And anyone scanning paper documents uses it to trim the edges automatically.
Yes. No sign-up, no watermark, no page limit and no daily cap. The tool runs entirely in your browser, so we have no per-user costs. We offer it free because it complements our paid CAD conversion service - if you ever need paper drawings turned into editable CAD files, you'll already know us.
No. Your files never leave your computer. The cropping happens in your browser using JavaScript - we don't send them to a server. That makes the tool safe for confidential drawings, NDA documents, signed contracts and anything sensitive.
Yes. The tool was built and tested with real CAD exports from AutoCAD, ArchiCAD, Revit, SketchUp, MicroStation and Vectorworks. Because it reads the PDF stream directly, it handles rotated pages, multi-page sets and scaled drawings correctly.
Yes. Drop or select multiple PDF files and the tool processes them in batch. When all files are done, you can download each one individually or grab the whole set as a single ZIP archive.
Acrobat's Crop Pages lets you draw a crop box manually. Our tool detects the content bounding box automatically across every page, with a single adjustable margin. For batches of CAD drawings this is much faster, and it doesn't require Acrobat Pro.
Yes. We change the page's crop box, not the underlying content. The cropped PDF prints, opens in any PDF reader, and re-imports cleanly into CAD or DTP software.
There's no hard limit - it's bounded by your browser's memory. In practice we've cropped PDFs up to a few hundred MB without issue. Very large multi-page sets may take a few seconds to process.
It works, but with a caveat: for image-only PDFs the bounding box is the image itself, so cropping mostly removes the page background. For best results on scans, run them through an OCR tool first or use our Large Format Scanning service which delivers already-cropped output.
Cropping a PDF is the first step. If your end goal is editable CAD, we can take it from there.
