About this converter

Reduce SVG markup without changing its visible text or artwork.

What happens to your file

For supported tools the file is read with the browser File API and held in memory on your device. It is validated, processed by the SVG tools engine in a Web Worker, and the result is handed back as a download. At no point is the file sent to a server.

What to expect from the output

The tool writes SVG. Formats differ in what they can represent, so expect simple structure to transfer reliably while detailed layout may be simplified by the target format.

How to use this converter

Four steps, none of which involve an account.

  1. 1 Choose your file

    Drop a svg file onto the drop area or browse for it.

  2. 2 Check the output

    The output format is preselected as SVG. Change it if the tool supports other targets.

  3. 3 Convert

    Everything happens on your device, so speed depends on your machine rather than a queue.

  4. 4 Download

    Save the result, then reset the tool to clear it from memory and start again.

Frequently asked questions

Answers specific to SVG Minifier.

Is this tool free?

Yes. SVG Minifier is free to use and needs no account, no sign-up and no email address.

Where is my file processed?

This tool is being built for local processing, so the file is handled by your own browser. Until that engine is connected the page shows an explicit notice instead of pretending the conversion succeeded.

Which files can I use as input?

Accepted formats are SVG. The converter writes SVG.

Are SVG files uploaded to a server?

No. SVG conversion and cleanup run locally in your browser. Active content and external linked resources are rejected.
