Will converting SVG to AVIF make the file smaller?
Usually, yes. A 12-megapixel photo is around 20 KB as SVG and around 1.4 MB as AVIF — roughly 70× larger. Because AVIF is lossless the result depends entirely on the image content — flat colour and text compress far better than photographic detail.
Does converting SVG to AVIF lose quality?
A little, by design. SVG is lossless and AVIF is lossy, so some detail is discarded in exchange for a much smaller file. At quality 80–90 the result is visually indistinguishable from the original for photographs. For screenshots, logos or anything with sharp text, stay with a lossless format instead — lossy compression creates visible halos around hard edges.
Is transparency preserved when converting SVG to AVIF?
Yes. Both SVG and AVIF support an alpha channel, so transparent and semi-transparent pixels carry across unchanged — a logo with a cut-out background stays cut out, and soft drop shadows keep their gradient rather than picking up a white halo. Because AVIF can compress lossily, a very hard edge against transparency may pick up slight softness at high compression; keep quality at 85 or above for cut-out graphics.
What happens to an animated SVG?
Only the first frame is converted. Every conversion here decodes one frame onto a canvas and re-encodes it, so the result is always a still image — that applies to AVIF as much as to any other target. To shrink an animation while keeping the motion, a video file (MP4 or WebM) is usually around a tenth of the size of the equivalent SVG, and needs an encoder we do not ship yet.
What resolution will the AVIF be?
SVG is vector, so it has no inherent resolution — it has to be rendered at a chosen pixel size. We use the SVG's declared width and height, or its viewBox if no size is set. Because you are converting from vector to pixels, the result stops being scalable: export at 2× the size you plan to display for sharpness on high-DPI screens.
How it works, and more about svg to avif
How it works
- Add your SVG file. Drag a SVG file onto the drop zone, or click to browse. You can select several at once.
- Choose your settings. Adjust the quality slider if you want a smaller file or a sharper result. 80 suits most photographs.
- Download the AVIF. Conversion runs on your device as soon as each file is added — no upload, no queue. Download each result when it is ready.
SVG and AVIF side by side
| SVG | AVIF | |
|---|---|---|
| Full name | Scalable Vector Graphics | AV1 Image File Format |
| Compression | Vector — resolution independent | Lossy or lossless |
| Transparency | Yes — alpha channel | Yes — alpha channel |
| Animation | Yes | Yes, in the format |
| Browser support | Universal in all modern browsers | Chrome 85+, Firefox 93+, Safari 16.4+ (March 2023), Edge 121+ |
| Typical 12 MP photo | ~20 KB | ~1.4 MB |
| Usually used for | Logos, icons, charts and illustrations | Performance-critical web images where every kilobyte counts |
On a typical 12-megapixel phone photo, the AVIF output comes out roughly 70× larger than the SVG original. These are order-of-magnitude figures for one kind of image — your own results will vary a great deal, because flat colour, text and line art behave nothing like photographic detail, and the quality slider moves the figure substantially.
What this tool actually produces
Not estimates. Each row below was produced by running the file through this page in a real browser and measuring the result, at the default quality of 82.
| Test image | SVG in | AVIF out | Change |
|---|---|---|---|
| Line-art diagram 1200 × 800, hard edges and large flat areas | 2 KB | 10 KB | +387% |
| Logo with transparency 512 × 512, flat colour on a transparent background | 518 B | 5 KB | +939% |
Every test image got larger. That is expected for this pair rather than a fault: AVIF is not the efficient choice for content that already suits SVG, and you are converting for compatibility or for editing headroom, not to save space. Measured in Chrome 150.0.7871.46; other browsers encode slightly differently.
What to watch out for
- Encoding is computationally expensive and noticeably slow
- Requires Safari 16.4+ (2023), so a small share of users still miss it
- Sparse support outside browsers — most desktop editors cannot open it
- Animation is lost. Only the first frame is converted — every conversion here decodes a single frame onto a canvas and re-encodes it, so the result is a still image whatever the target format. To shrink an animation and keep the motion, a video file is typically around a tenth of the size of the equivalent SVG.
About the two formats
SVG is not pixels at all — it is XML describing shapes, so it stays perfectly sharp at any size and is usually a few kilobytes. That makes it ideal for logos and icons and useless for photographs. Converting a photo to SVG is not really possible; converting an SVG to a raster format is just rendering it at a chosen size.
AVIF currently produces the smallest files of any widely supported format — commonly half the size of JPEG at the same perceived quality, with excellent handling of gradients and noise. The cost is encoding time, which can be seconds per image rather than milliseconds, and support that only became universal with Safari 16.4 in 2023.
