SVG Compare — Compare SVG Files Online Free
An SVG is an image you can read — and diff. Compare icon and graphic source: changed paths, fills, and attributes pinpointed exactly. Free, no registration, artwork stays local.
How to Compare SVG Files Online
Comparing two SVG files with SVG Compare takes under a minute:
- Open the original .svg file into the left panel.
- Then upload the updated .svg file on the right side.
- Choose Compare and each edit lights up in color.
Tip: re-export from the same design tool when possible — different exporters restructure markup, which adds noise to the diff. Works in every current browser — Safari, Chrome, Firefox, or Edge — on any desktop or mobile system, with unlimited comparisons. Free side-by-side comparison is the default, no account required; Premium adds the line-by-line and single-view modes.
Understanding the SVG File Format
SVG (Scalable Vector Graphics) is the W3C's XML-based vector image format — icons, logos, illustrations, and charts defined as code: paths, shapes, transforms, and styles. Because SVGs are text, they can be diffed like source code, which is the only precise way to see what changed between two versions of an icon or how an optimizer altered a file. Because the picture is markup, SVG file comparison can be exact in a way pixel-based image comparison never is — a changed viewBox or a recolored fill is one highlighted attribute, not a vague visual impression.
Common Uses of SVG Files
Typical real-world jobs for this tool:
- Design systems audit icon-library updates export by export.
- Developers check why two 'identical' logo exports behave differently.
- Teams verify an SVG optimization pass changed size, not appearance.
- Designers compare Figma and Illustrator exports of the same asset.
- Engineers diff inline SVG between deploys when icons break.
- Brand teams confirm a vendor's delivered assets match approved versions.
Design systems audit icon updates by diffing exports, since two visually identical icons can carry wildly different markup, size, and metadata.
Differences Detected in SVG Files
The tool highlights SVG's structural elements: SVG path diff for changed d-attribute geometry, viewBox comparison catching coordinate-system changes that break rendering, SVG attribute changes (fill, stroke, class), animation diff for SMIL/CSS animation edits, and SVG transform comparison where translate/scale/rotate values shifted.
Examples of Changes Found in SVG Files
Vector-source changes the element diff typically reveals:
- An icon where the viewBox changed from '0 0 24 24' to '0 0 20 20' — a sizing-breaking change flagged instantly.
- A path whose d attribute was simplified by an optimizer, with the geometry differences highlighted.
- A logo where fill="#1a1a1a" changed to fill="currentColor" for theme support.
- An exported illustration where a <title> element was stripped during optimization — an accessibility regression caught in review.
- A logo where fill="#1A1A1A" became fill="currentColor" — invisible on the homepage, invisible-on-dark-mode everywhere else, explained by one attribute.
Why Use FileDiffs for SVG Comparison
An SVG is an image written as markup, which makes its diff exact in a way pixel comparison never is, a changed path, a recolored fill, an edited viewBox is one highlighted attribute rather than a vague visual impression. FileDiffs compares the source in the browser. The page is built for design-system and icon-library work, with examples like a logo's fill changing from a hex value to currentColor, invisible on one background and invisible-on-dark-mode everywhere else, explained in a single line.
Frequently Asked Questions About Compare SVG Files Online
Upload both .svg files and the tool diffs them as code, highlighting every changed element, path, attribute, and transform. Because the image is markup, the comparison names the exact changed attribute instead of a vague visual impression.
Compare the icon files across versions; changed paths, fills, and viewBox values are flagged precisely — visual squinting can't match code-level comparison. Re-export both icons from the same design tool when possible — different exporters restructure markup and add noise.
The element-level highlights show modified d attributes, added/removed shapes, and changed groups at their exact lines, making geometry edits reviewable. Path data highlights pinpoint reshaped curves; fill and stroke highlights catch recolors — read them separately.
No — PNG is a raster bitmap with no comparable source. To compare an SVG with a raster image visually, export the SVG to PNG and use an image-comparison approach; for code-level diffs, both files must be SVG.
Diff the new file against the previous version, prioritizing viewBox, path data, and accessibility elements (title, desc, aria attributes) — the highest-impact change areas. Icon-library updates deserve this audit: visually identical icons can differ wildly in size, metadata, and structure.
Yes. Vector source is processed locally in your browser, so brand assets and unreleased graphics never leave your machine. Nothing is stored after you close the tab. There is no account, no log, and no server copy at any point.
