Revision Compare
Drop the old and new revision of a drawing and see exactly what changed — every added, removed and changed line of text, plus a colour overlay that highlights where the drawing moved on the page. Both files are compared on your own device and never leave it. The text comparison needs a digital PDF with a text layer; the visual overlay works on any drawing.
Frequently asked questions
Are my drawings uploaded?
No. Both files are opened and compared entirely in your browser; nothing is sent anywhere.
What does it compare?
The text content of both revisions — every added, removed or changed line — plus a visual pixel overlay showing exactly where the drawing changed.
Does it work on scanned drawings?
The text diff needs digital PDFs with a text layer. The visual overlay works on any PDF, scanned or digital.
