About SVG Diff
Compares two SVGs structurally (XML tree) or visually (rasterized). Useful for icon updates, generated charts, and design-system edits.
How to use
- Paste or load both SVG files.
- Set Compare as to Rendered or Markup under Options.
- In Rendered mode pick a Render scale, then set Background if your SVGs depend on a page colour.

An icon redesign from a circle to a rounded square.
What this tool doesn't handle
- External references (xlink:href to other files) are not fetched.
- CSS animations are not run; comparison is at a static state.
Frequently asked questions
Do my files ever leave my browser?
No. Every comparison runs locally in your browser. Nothing you paste, drop, or load is uploaded to a server; the tool keeps working even if you go offline after the page loads.
Is this tool free to use?
Yes. All DiffResolver tools are free, with no account, sign-up, or installation. Because processing happens on your device, there are no server-imposed usage limits.
Should I compare SVGs as Markup or as Rendered?
Markup shows exactly which elements and attributes changed, ideal for hand-edited icons. Rendered draws both files as images and compares the pixels, catching changes that look unrelated in the markup.
Why does my SVG come out blank in Rendered mode?
SVGs that reference external files or assume a page background can render as empty or transparent. Set Background in Options and inline any external references.
Is there a file size limit?
No server limit applies, because nothing is uploaded. The memory of your device sets the practical limit. Above 10 MB for text, 40 MB for images, 100 MB for documents, or 500 MB for archives, the tool warns you that the work can be slow, but it never blocks the file.
Does this tool work offline?
Yes. The browser keeps a copy of the tool after the first visit, so a page you opened before still works without a network. You can also install DiffResolver as an app from the browser menu. Installation stays optional; the site works the same in a normal tab.
Where is my data stored?
Your files are stored nowhere. They stay in the memory of the page and are gone when you close the tab. Only what you save yourself stays in this browser: a snapshot, your tool options, and your theme. To remove it, open Settings and select Clear all local data.
