KordFree diff tool
Compare two SVG files
Diff two SVG files in your browser, free, no account: compare two revisions of an exported diagram or schematic as drawings, not as XML. Built by Kord; opens with a sample architecture-diagram pair loaded.
Free, no account. Opens with a two-revision system architecture diagram loaded.
SVG is what diagrams become on their way out of draw.io, Mermaid, Inkscape, and half the documentation toolchains in use. Two revisions of one diagram are two XML files, and a text diff of them is technically accurate and practically unreadable - a moved box rewrites coordinates on every element near it.
Drop the two files here and compare them as drawings. Free, no account, and it opens with a sample system-architecture pair loaded.
What the comparison shows
What you get on screen once both files are in, and why each piece is there:
- Drawings, not markup. The comparison renders both revisions - what a reader of the diagram would see changed, not what the serializer did.
- Sharp at any zoom. Vector in, vector rendered - zooming into a dense corner costs nothing.
- A link for the docs review. Share the comparison instead of pasting two screenshots into a thread.
How to compare two SVG diagrams
Three steps, none of which is signing up:
- Open the diff tool - it loads with a two-revision system architecture diagram already compared, so you see the result shape before committing your own files.
- Drop your two SVG diagrams into the Before and After slots - up to 25 MB each.
- Read the comparison. If someone else needs to see it, Share turns it into a link.
FAQ
The questions people ask before dropping real files on a free tool, answered plainly:
Is it free?
Yes. No account, no trial clock, no watermark. The tool exists because we build Kord, version control for engineering document sets, and a diff you can run in ten seconds explains the product faster than any brochure.
Do my files get stored?
Files are kept only as long as it takes to draw the comparison. Most formats render in your browser; Word and PowerPoint are converted to a preview by our servers in memory, and a file too big to ride a request travels through a short-lived upload that is deleted automatically. There is no account, so there is no history to attach anything to. The longer answer is at work.withkord.com/security.
Why does a text diff of SVG read so badly?
Because layout engines rewrite coordinates wholesale: nudge one shape and every neighbor's x and y can change. The picture changed a little; the XML changed everywhere. Comparing the rendered drawing sidesteps the whole problem.
When two files aren't the real problem
A one-off diff answers a one-off question. If your team compares SVG diagrams every revision cycle - and the revision that matters sits next to drawings, specs, and calc sheets that have to agree with it - that is the job Kord exists for: version control on the whole document set, this same visual comparison between any two revisions, and review sessions with sign-off before anything is issued. The longer argument is in Git for documents.
