SVG optimizer

Minify SVG files or convert SVG to PNG, WebP or AVIF at any scale — right in your browser, no upload.

How to optimize an SVG

  1. Drop or pick an SVG file.
  2. Keep the safe default, or flip on aggressive minification for extra savings when no external CSS/JS references your SVG's IDs.
  3. Optimize, check the before/after view, and download — the viewBox and visual output stay identical, only the bytes shrink.

SVG to PNG, WebP or AVIF

Need a raster copy — an SVG to PNG conversion for a favicon, an app store asset, an email client, or anywhere vector graphics aren't welcome? Switch to the Convert to image tab. Because SVG is resolution-independent, you choose the output size: 1× of the document's own dimensions, crisp 2× or 4× exports for high-DPI screens, or an exact custom width with the height following the aspect ratio. Transparency is preserved in every format, and the same Rust/WebAssembly encoders behind our Convert tool produce the PNG, WebP or AVIF bytes — all without your file ever leaving the browser.

Why optimize SVG files?

SVGs exported from design tools carry editor metadata, comments, hidden layers and absurdly precise coordinates that browsers never need. Stripping them routinely cuts 30–70% of the file size — faster pages, smaller bundles, better Core Web Vitals — while rendering pixel-identically. OptImg runs SVGO, the industry-standard optimizer, entirely client-side: if a file is already tight, we tell you instead of handing back a bigger one.

Frequently asked questions

Is my SVG uploaded to a server?
No. Both optimization and conversion run entirely in your browser — your file never leaves your device, there is no queue, and no file-size limit beyond your device's memory.
How do I convert SVG to PNG?
Drop your SVG, switch to the “Convert to image” tab, keep PNG selected, and hit Convert. You get a pixel-perfect PNG at the SVG's original size — or at 2×, 4×, or any custom width you choose.
Does converting SVG to PNG keep transparency?
Yes. The transparent background of your SVG stays fully transparent in PNG, WebP and AVIF output — nothing is flattened onto white.
How do I get a high-resolution PNG from an SVG?
SVGs are resolution-independent, so pick 2× or 4× for crisp exports on high-DPI screens, or enter an exact pixel width — the height follows the SVG's aspect ratio automatically.
Can I turn an SVG into WebP or AVIF instead of PNG?
Yes — choose WebP or AVIF in the format picker. Both keep transparency and are much smaller than PNG; a quality slider (defaults: WebP 80, AVIF 60) lets you trade size for fidelity.
What does the optimizer actually remove?
Editor metadata, comments, hidden elements, default attributes and redundant precision — the classic SVGO cleanup. The safe default never renames IDs; the aggressive toggle additionally minifies IDs and rounds coordinates to 2 decimals for extra savings.
Will optimizing remove the viewBox or break responsive scaling?
No. The viewBox is always preserved, in both safe and aggressive mode, so responsive SVGs keep scaling exactly as before.
Why does text look different after converting?
Fonts referenced by an SVG are never downloaded (everything stays on your device), so text renders with a bundled Noto Sans fallback. Convert text to paths in your design tool before exporting for exact glyphs.
Can I convert a PNG or JPG into an SVG?
No — raster-to-vector tracing is a different craft and out of scope here. This tool optimizes SVGs and converts SVG to PNG, WebP or AVIF, not the reverse.
