A free tool to crop a PDF - automatically trimming the white margins around the content. Built for PDFs exported from AutoCAD and other CAD software, plus vector drawings, scanned PDFs and multi-page documents - all in your browser. No upload, so your files never leave your computer.
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.
When you plot a drawing to PDF from AutoCAD, the sheet almost always carries a wide white border around the drawing frame. You can fight it by redefining the plot window every time - or you can just crop the finished PDF here. Plot to PDF as normal, drop the file onto the tool above, and it finds the drawing's content bounding box and trims the surrounding white space in one click. It works the same way on drawings from AutoCAD LT, Civil 3D, Revit, ArchiCAD, MicroStation and Vectorworks, on single sheets and on multi-page plot sets, and on large formats like A0 and A1. Because it reads the PDF's vector stream directly, lines and text stay razor-sharp - nothing is rasterised. And since the whole thing runs in your browser, your drawings are never uploaded, which matters when the sheet is confidential or under NDA.
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.
You don't need to do it inside AutoCAD. Plot or export your drawing to PDF as usual, then drop the file onto the tool above - it detects the drawing's content bounding box and trims the surrounding white space automatically, so there's no need to redefine a plot window each time. It handles single sheets and multi-page plot sets, including A0 and A1 drawings, and keeps every line and label sharp because nothing is rasterised.
It's completely private. Nothing is uploaded and nothing is stored. The crop runs entirely in your browser, so your PDF never touches a server - unlike upload-based tools that send your file to their cloud. That makes it safe for confidential, NDA and commercially sensitive drawings.
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.
