SVG Optimizer
SVG Optimizer, free and online. Convert SVG to SVG and get clean vector paths that scale to any size. Reads the SVG at any size, so the result is as sharp as you need. Runs in your browser: nothing uploaded, no sign-up.
Works with: any browser
Drop several files at once to convert the whole folder in one pass. Got a different format? A PNG, JPG, HEIC, PDF, SVG or DXF still comes out as SVG.
Or paste SVG code
× removes a colour and its shapes; click a swatch to change it. Every format follows.

Batch
Every file is traced on its own at its own resolution, with the settings in the panel. A file converted here comes out identical to the same file converted by itself.

Machine output
Height follows the source aspect ratio.
Laser and Router follow the traced outlines. Engrave photo burns the picture itself, line by line, for photos and portraits.
Heat transfer vinyl is pressed face down, so it has to be cut mirrored. The second box is the overcut in millimetres: a drag knife starts each shape pointing the wrong way, and running past the start covers that stretch properly so the piece weeds out clean.
Beam or bit width. Left at zero the tool runs down the centre of the line, so a part finishes one tool width undersize. Set it and the path is offset by half, with holes offset the opposite way.
Holes before the part that holds them, so nothing comes loose while there is still cutting to do. Also shortens the travel between cuts.
See it on your product
Put this artwork on a 3D mug, tumbler, sign, phone case or canvas, turn it all the way round, or drop it onto a photograph of your own blank. The preview page has the product picker, the colours and the placement controls.

Upload the file
SVG and EPS are parsed; rasters are re-encoded.
Choose how hard to squeeze
Coordinate precision for vectors, quality for JPEG. The size saved is shown as you change it.

SVG optimizer: smaller SVG files that look the same
An svg optimizer removes what the eye never sees: editor metadata from Illustrator and Inkscape, empty groups, hidden layers, and coordinates written to eight decimal places. Optimize svg files here and they are often a third to half the size, drawn the same.
Use it as an svg minifier for the web, to compress svg icons before a site build, or to reduce svg file size before uploading to Cricut or Etsy, which refuse or slow down on large files. As an svg path optimizer it rewrites path data in its shortest form: relative moves, dropped repeat commands, and coordinates rounded to a precision you choose.
Why it matters
Lossless by default
Vector optimisation only rounds coordinates and strips editor metadata. The geometry is unchanged unless you lower the precision yourself.
Real reductions
Redundant closing segments, editor namespaces, comments and over-precise coordinates typically account for a third to a half of an exported SVG.
Transparency handled properly
JPEG has no alpha channel. We fill white behind transparent areas rather than letting them encode as black.
See what changed
Before and after byte counts, and the optimised file rendered, so nothing is thrown away silently.
Questions
Will optimizing change how my SVG looks?
No. Only invisible data and excess precision are removed. At the default two decimal places the change is far below anything a screen or a cutter can resolve.
Why is my SVG file so big?
Usually an embedded bitmap, thousands of tiny path nodes from auto-tracing, or editor metadata. The optimizer strips the metadata and precision; the cut-ready checker tells you if there is a bitmap inside.
Is this like SVGO?
It does the same kind of safe clean-up SVGO does, in the browser, with no install.
Will optimising break my SVG?
Editor-specific attributes are removed, so the file may no longer round-trip perfectly into Inkscape or Illustrator with their own state intact. The rendered result is identical.
How much smaller?
Typically 30 to 50 percent for an exported SVG, more if it came out of a design tool with metadata attached.
Does it change my colours?
No. Colour values are left exactly as they are.
