What it checks
Four areas, graded against one use case — a logo on the web. Each gets Good, Warning, or Critical, and the report spells out the fix inline.
- Structure —
viewBox, embedded bitmaps, scripts, editor junk, accessibility. - Complexity — path, node, and group counts, plus coordinate precision.
- Effects — gradients, filters, masks, and strokes, weighted by render cost.
- File size — how close it is to a lean, optimized logo.
Private by designThe file is read and parsed in your browser — nothing is uploaded or stored. It works offline.
FAQ
Is my logo uploaded to a server?
No — analysis runs entirely in your browser. No account, nothing stored.
My logo scored Critical — is it unusable?
Not necessarily, but it has an issue worth fixing — often a missing viewBox, an embedded bitmap, or a script tag. Apply the inline fix and re-check.
