SVG to AVIF Converter

Render an SVG into an AVIF image — the smallest raster version of vector artwork you can make, with transparency intact. A logo drawn at 1024 pixels came out at about 4 KB, roughly a quarter of the same render as PNG. The question worth a minute is how clean the edges stay, and the measurements below answer it.

Output width

SVG is a vector format, so it can be rendered at any size without losing sharpness.

Step by step

How to convert SVG to AVIF in 3 steps

  1. Choose a width — the largest size the image will be displayed at

  2. Leave quality at 75, or raise it to 90 for effectively lossless edges

  3. Add your SVG and download the AVIF

Format comparison

SVG vs AVIF

SVG (Scalable Vector Graphics)

Vector

Describes shapes and text as instructions rather than pixels, so it can be drawn sharply at any size.

  • Crisp at any size, from favicon to billboard
  • Very small files for logos, icons and diagrams
  • Cannot represent a photograph, and many apps cannot import it

AVIF (AV1 Image File Format)

Lossy or lossless

The newest widely supported web format, built on the AV1 video codec and designed for the smallest files.

  • Usually the smallest file at a given visual quality
  • Supported by current Chrome, Edge, Firefox and Safari
  • Slow to encode, and unsupported by much older software

When you need pixels rather than vectors

On a website an SVG is usually best left as an SVG: it is tiny and sharp at any size. But there are good reasons to need a raster image instead — a platform that does not accept SVG, an image that should not expose its drawing code, social previews and email, which rarely support SVG, or artwork with filters that render inconsistently across browsers.

When pixels are needed, AVIF gives the smallest file. Measured with a small logo at each width:

  • 512 px — 2.1 KB.
  • 1024 px — 4.2 KB.
  • 2048 px — 7.1 KB.
  • 4096 px — 13.9 KB.

For comparison, the same artwork at 1024 pixels was 15.7 KB as PNG, 21 KB as TIFF and 2.1 MB as an uncompressed BMP.

How clean are the edges?

AVIF is lossy, and vector artwork is all hard edges — exactly where lossy compression shows first. So we measured it, comparing each AVIF against a lossless render of the same SVG after placing both on white and on black backgrounds, as they would appear on a page:

  • Quality 75, the default: along edges the colour differs from the lossless render by under 2 levels out of 255 on average. Invisible at normal viewing size.
  • Quality 90: effectively lossless — the largest difference anywhere on an edge was 6 levels — at 6.8 KB, still well under half the PNG's size.

For a logo that must be pixel-perfect under close inspection, choose 90. For everything else, 75 is indistinguishable and smaller.

Quality

Quality and file size

Transparency

SVG artwork is usually drawn on a transparent background, and the AVIF keeps it as a full alpha channel, so the image sits cleanly on any background colour.

Choosing the width

The render is drawn at the width you pick, so it is fully sharp at that size and cannot be enlarged later without softening. Choose the largest size the image will genuinely be shown at. On high-density screens, which display two or three device pixels per CSS pixel, that means double or triple the layout width — a logo laid out 200 pixels wide needs 400 pixels on a 2× screen and 600 on the 3× screens of many phones, so the 1024-pixel option covers both.

Fonts

Text in a named font, rather than converted to outlines, is drawn with whatever matching font the renderer has, which may differ from your design. Convert text to outlines before exporting the SVG.

Browser support

Every current major browser displays AVIF: Chrome, Firefox, Safari and Edge. Some email clients and older software do not. For email and wide compatibility, PNG is safer; WebP is a good middle ground.

When SVG to AVIF makes sense

  • Platforms that do not accept SVG uploads, which is many of them.
  • Open Graph and social preview images for pages that serve AVIF.
  • Complex illustrations with many paths, gradients or filters, where a raster image is lighter and renders identically everywhere.
  • Performance-sensitive pages that need raster artwork at the smallest possible size.

AVIF, WebP or PNG?

  • AVIF — smallest. 4.2 KB at 1024 px, quality 75.
  • WebP — slightly larger (6.2 KB at quality 75), and supported more widely outside browsers.
  • PNG — lossless and universally supported, at 15.7 KB.

Is uploading an SVG safe?

SVG files can contain scripts and references to external resources, so every upload is screened before anything reads it: files with scripts, external references or document type declarations are refused outright rather than cleaned up. The output is a plain image, so nothing from the SVG can run.

What happens to your file

SVGs are rendered on our server, where they can be screened. Your upload is deleted the moment conversion finishes, the result is deleted as you download it, and anything abandoned is swept automatically.

Privacy

What happens to your file

This tool runs on our server, so it works the same on every phone and computer. Your file is uploaded, and this is exactly what happens to it:

  • Stored outside the public web root under a random name, never under your file's name.
  • Processed, with the original upload deleted immediately — whether it succeeded or failed.
  • The result sits behind a signed link that only you receive, which stops working after 20 minutes, and the file is deleted the moment you download it.
  • Anything never collected is deleted automatically within 30 minutes.
  • The image itself is never logged or kept. If a conversion fails, we record the formats involved and the error — not the file.
  • Camera metadata, including any GPS coordinates recording where a photo was taken, is removed from the result. Only the rotation needed to show the image the right way up is kept.

Questions & answers

SVG to AVIF: frequently asked questions

How small will my AVIF be?

Very small. A logo measured 2.1 KB at 512 px, 4.2 KB at 1024 px, 7.1 KB at 2048 px and 13.9 KB at 4096 px. At 1024 px the PNG of the same artwork was 15.7 KB.

Will the edges of my logo look soft?

Not at the default. We compared AVIF renders against a lossless render on white and black backgrounds: at quality 75 edge colours differed by under 2 levels out of 255 on average. At quality 90 the largest edge difference anywhere was 6 levels — effectively lossless — at 6.8 KB.

Is transparency kept?

Yes. The AVIF carries a full alpha channel, so artwork drawn on a transparent background sits cleanly on any page colour.

What width should I choose?

The largest size the image will be shown at, allowing for high-density screens: an image laid out 200 pixels wide needs 400 px on a 2× screen and 600 px on a 3× phone screen, so 1024 px covers both. The render cannot be enlarged later without softening.

Should I just keep the SVG?

On your own website, often yes — SVGs are tiny and sharp at any size. Convert when a platform does not accept SVG, for social previews and email, or for complex artwork that renders inconsistently.

AVIF, WebP or PNG?

AVIF is smallest (4.2 KB at 1024 px). WebP is slightly larger at 6.2 KB and more widely supported outside browsers. PNG is lossless and universal at 15.7 KB.
