SVG Optimiser
Strip an SVG of everything the editor left behind, with a before-and-after preview so you can see nothing broke.

What it does
SVG Optimiser works on SVG images and writes a new file; the one you dropped in is untouched. Smaller markup, same drawing.
When you need it
Usually because something downstream has an opinion: a profile photo that must be square, a marketplace that rejects anything over a certain width, a print that needs the right proportions, or a phone photo that arrived rotated.
Limits and caveats
Enlarging an image cannot add detail that was never captured, so scaling up softens it. Saving to a lossy format re-encodes the pixels, which is worth doing once rather than repeatedly on the same file. Everything happens in your browser, so the file never leaves your device.
How to svg optimiser
- Drop an SVG straight out of Figma, Illustrator or Inkscape.
- Compare the two previews — optimisation can break a drawing.
- Copy the markup, or download the file.
Frequently asked questions
- Will it break my icon?
- It can, which is why both versions are shown side by side. The viewBox is deliberately never removed — dropping it is what makes an SVG stop scaling, and it is the most common complaint about optimisers.
- What is coordinate precision?
- How many decimals each point keeps. Editors write fifteen; a screen cannot show the difference past two or three, and every digit costs bytes on every point.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
