SVG Cleanup Tool

Optimize an SVG copy, then inspect it

Upload SVG only for this action. Keep your original file separately. The service checks SVG safety before optimization and again afterward; malformed or unsupported content may be rejected. A rejection is not a diagnosis that your artwork is visually wrong, and retrying it does not repair its geometry.

What the optimizer can change

The configured SVGO transforms remove some editor noise, comments and empty containers, convert shapes and styles, and optimize path commands. The configuration disables ID cleanup; it does not promise shortened IDs. Path coordinate precision can change, and node counts or bytes may not decrease for every input. It does not identify which tiny marks are intentional or automatically close broken contours.

Descriptions and references need a separate check

Editor metadata is different from an accessible title or description. This configuration includes removal of desc elements and dimensions, so the output must be checked in its final embedding. Do not discard title or desc content categorically because the artwork is an icon. Verify the accessible name, description, viewBox, layout dimensions and any IDs used by CSS, gradients, clips or repeated objects. Keep the original when those dependencies are not preserved.

A measured local cleanup example

This owned badge was processed locally with the current cleanup function on Node 22.23.2. The untouched SVG is 631 UTF-8 bytes; stripping its inert comment produces a 593-byte processed input; optimization produces 507 bytes. These counts describe this file only, not a promised reduction for your artwork.

In this run the title, description and gradient IDs remained, and every referenced ID resolved. That is an observation for this fixture, not a general accessibility guarantee. A 200 × 100 local raster comparison found 282 changed color/alpha channel values; byte reduction does not establish identical rendering or a faster page.

Inspect the original SVG, processed input and optimized SVG. This direct function test did not exercise an upload session or a receiving editor.

A precision-sensitive example

Illustrative arithmetic, not a tool-output screenshot: rounding a coordinate from 0.004 to 0.00 changes it by 0.004 units. A scale of 1000 can make that a four-unit displayed difference. The effect of rounding depends on the coordinate system and transforms, not just the number of decimal places. Compare small gaps and strokes at the intended size.

Read the paired preview carefully

The panel labelled Processed input shows the safety-qualified, editor-noise-stripped copy, not necessarily your untouched upload bytes. Compare with your separately retained original as well. Inspect holes, overlaps, white artwork, gradients and fine detail; then reopen the downloaded SVG in the intended application. Record actual file-size changes only for that exact input and output.

Choose another repair when needed

Use deliberate editor repair for wrong contours, fragments or layering. Use rendering diagnosis for a distorted viewBox or missing reference. A smaller optimized SVG is not automatically faster on a page or accepted by a cutting application; those outcomes require their own checks.
