SVG to AVIF Converter
Convert SVG to AVIF in your browser. The SVG is sanitized and rendered at the pixel size you choose, so it is sharp at any resolution you ask for. You get an AVIF encoded with libavif (AV1) compiled to WebAssembly, at the quality you choose. Nothing is uploaded.

How to use SVG to AVIF
- 1
Add your SVG files: drop them here, choose them, or paste from the clipboard.
- 2
Set the quality. AVIF quality numbers run lower than JPEG: around 55 to 65 already looks excellent. Encoding is slow on phones.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.

Download the .avif files one at a time or together as a ZIP.
Why use Aback Images for svg to avif
Where the AVIF goes next
AVIF opens in Chrome, Edge, Firefox, Safari 16 and later, Windows 11 Photos, macOS Preview and recent editors.
AVIF next to SVG
Rasterising turns a description of shapes into stored pixels, so the AVIF is usually larger than a small SVG, and grows with the size you render at.
The first lossy pass
The SVG holds not fixed: coordinates and colours are continuous values with nothing discarded yet. This conversion is the first lossy encode these pixels see, and hard edges and flat colour show it first.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
SVG vs AVIF
What changes from SVG to AVIF
Encoding: the SVG uses XML text describing paths, shapes and text, sometimes gzipped as .svgz; AVIF uses lossy or lossless AV1 intra-frame coding, and the download is an AVIF encoded with libavif (AV1) compiled to WebAssembly, at the quality you choose.
Bit depth: not fixed: coordinates and colours are continuous values in the SVG; AVIF allows 8, 10 or 12 bits per channel, and the AVIF written here has 8 bits per channel.
Colour: sRGB by default, other spaces through CSS colour functions in the SVG; AVIF supports YUV 4:4:4 or 4:2:0 with BT.709, Display P3 or BT.2020 primaries, HDR curves possible, written here as 8-bit sRGB.
Transparency: the SVG stores it as opacity on any element, with anti-aliased edges; the AVIF keeps it as an auxiliary AV1 image stored beside the colour image.
Animation: SMIL or CSS animation described in the markup; a single still rendering is converted.
Metadata: the SVG can carry title, description and RDF metadata elements; AVIF can carry EXIF, XMP and ICC stored as HEIF items, but nothing is copied across.
About SVG
SVG describes shapes, paths and text as XML instead of pixels, so it stays crisp at any size. It is the standard for logos, icons and illustrations on the web.
An SVG is an XML document: a root <svg> element with a viewBox, then paths, shapes, text, gradients and filters. It can also embed raster images and, dangerously, scripts, which is why untrusted SVG is sanitized before rendering here.
SVG files usually come from icon sets, logos, design tools (Figma, Illustrator, Inkscape) and diagram exports.
About AVIF
AVIF uses the AV1 video codec for still images. It is the most efficient widely supported format, often half the size of JPEG, with HDR, wide colour and transparency, but encoding is slow.
An AVIF is a HEIF file, the same ISO base media boxes as MP4, with the brand 'avif'. The picture is an AV1 key frame stored as an image item, and its size, colour and pixel layout are item properties.
When converting SVG to AVIF makes sense
AVIF is the better choice for maximum compression on modern websites, while SVG suits logos, icons and illustrations.
AVIF strengths: Often 50% smaller than JPEG; Excellent at low quality settings; Transparency, HDR and 10/12-bit colour. Drawbacks to weigh: Slow to encode, especially on phones; Not supported by some older software; Can smooth away fine texture at low quality.
Limitations
- Rasterising fixes the picture at one pixel size; set a larger size under More options if you need to print or zoom.
- Text that was not converted to outlines is drawn with the fonts on this device, so lettering can look different from the designer's screen.
- AVIF encoding is CPU-heavy, so large images and big batches take noticeably longer than JPG or WebP, especially on phones.
- Some older apps and operating systems cannot open AVIF yet; keep a JPG copy if you share the file widely.

Frequently asked questions
Does converting SVG to AVIF lose quality?
AVIF is lossy, so detail the eye barely notices is discarded to save space.
What resolution will the output be?
SVG has no fixed pixel size, so it is rendered at its declared width and height. Use the resize options to render it larger: because it is vector, an SVG stays perfectly sharp at any size you choose here. Files are sanitized first, so scripts and external references never run.
What quality should I choose for AVIF?
AVIF quality numbers run lower than JPEG: around 55 to 65 already looks excellent. Lower values give much smaller files with gentle softening. Encoding is CPU-heavy, so large batches take a while on phones.
Which apps open AVIF files?
Chrome, Edge, Firefox, Safari 16 and later, Windows 11 Photos, macOS Preview and recent editors. It opens in Chrome 85+, Edge, Firefox 93+ and Safari 16+.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
