Convert SVG to AVIF
AVIF makes the smallest raster copy of vector art that still keeps transparency — flat colors and clean gradients compress remarkably well. Pick a scale (1–4×) for the resolution you need. I default the quality to 70 here rather than 60, because crisp vector edges show compression artifacts earlier than photos do.

How it works
Drop in SVG files and choose an export scale from 1× to 4× — it multiplies the size the SVG declares.
The vector renders to pixels first, then encodes to AVIF at quality 70, a notch above my photo default to protect crisp edges.
Zoom the preview on thin strokes and small text before committing, then save each AVIF or the whole batch zipped.
SVG vs AVIF
Vectors against a raster codec is really a question of destination: on your own site the SVG wins unconditionally, but everywhere vectors are blocked, AVIF produces the smallest faithful stand-in with alpha intact. Quality 70 keeps its one weakness — softened hairlines — mostly out of sight.
| SVG | AVIF | |
|---|---|---|
| Compression | Vector (XML text) | Lossy or lossless |
| Transparency | Yes (full alpha) | Yes (full alpha) |
| Animation | Yes (CSS/SMIL) | Yes (rarely used) |
| Support | All browsers; often rejected by upload forms | All current browsers (Safari since 16.4, 2023) |
| Best for | Logos, icons, illustrations | Hero images and photo-heavy pages |
Frequently asked questions
No — that is the whole reason I built this. The conversion runs in your browser using WebAssembly, so your files never leave your device; there is no server in the loop at all. It also means the tool keeps working offline once the page has loaded, and there is no file size limit beyond your device’s memory.
SVG is a vector format — it has no fixed pixel size, so you decide the output resolution. The scale multiplies the SVG’s declared size: a 100×100 icon at 3× renders as a 300×300 raster. Because the rendering happens from vectors, every scale is perfectly sharp — pick the size your use case needs rather than upscaling later.
When the destination is the web and bytes matter — thumbnails of icon sets, social cards, previews on platforms that block SVG. For pixel-perfect edges at any cost, PNG remains the safest export; for everything web-facing, AVIF is usually a fraction of the PNG’s size.
Yes — AVIF carries a full alpha channel, so unpainted areas of the SVG stay properly transparent, anti-aliased edges included. Logos and icons drop onto any background without halos.
Your own site should serve the SVG: infinitely sharp, usually tiny, styleable with CSS. The AVIF raster is for the places that refuse vectors — social preview cards, marketplaces, badge hosts, email. So the real question is not either/or: keep the SVG canonical, export AVIF copies sized for each destination.
When the artwork is mostly hairline strokes and small text — lossy coding softens those first, and at quality 70 you may see it. SVG to PNG keeps every edge mathematically crisp and, for simple flat-color icons, is often barely bigger than the AVIF anyway. AVIF pulls ahead as art gets larger and more gradient-heavy.
