How to convert SVG to AVIF
- Click Choose files or drop your SVG images into the box above — up to 10 at a time on the free plan.
- Optionally set the quality — AVIF takes a few seconds per photo to encode.
- Conversion starts right away. Download each AVIF file, or click Download all to get them as one ZIP.
SVG vs AVIF
| SVG | AVIF | |
|---|---|---|
| Compression | Vector (no pixels) | Lossy or lossless |
| Transparency | Yes | Yes |
| Animation | Yes | Yes |
| Colors | Vector shapes: no pixels, sharp at any size | 8, 10 or 12 bits per channel, HDR |
| File size (photos) | Tiny for icons and logos | Smallest |
| Opens on | Every browser and design tool; not accepted by many upload forms and office apps | Chrome 85+, Firefox 93+, Safari 16+; few desktop apps and editors |
| Best for | Logos, icons and illustrations that must stay sharp at any size | The smallest possible web images with high quality |
About SVG and AVIF
What is SVG?
SVG describes an image with shapes and paths instead of pixels, so it stays perfectly sharp at any size. It is the standard format for logos and icons on the web. Many apps, social networks and upload forms only accept pixel images, so SVGs often need to be rendered to PNG or JPG at a chosen size.
- Infinitely scalable, always sharp
- Tiny files for logos and icons
- Editable as text
- Not accepted by most social networks and upload forms
- Not suitable for photos
What is AVIF?
AVIF is a modern image format based on the royalty-free AV1 video codec. It usually beats both JPG and WebP on file size — often around half of a comparable JPG — and supports transparency, HDR and wide color. Encoding it takes noticeably longer than JPG or WebP, and support outside web browsers is still limited.
- Best compression of any common format
- Transparency, HDR and wide color
- Royalty-free
- Slow to encode
- Limited support in desktop apps and editors
Why GlideConvert?
- Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
- Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
- Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.
Frequently asked questions
Will converting SVG to AVIF reduce quality?
AVIF uses lossy compression, but at the default quality of 90% the difference is practically invisible, even though the SVG was already compressed. Move the quality slider down for smaller files, or up to 100% for the best possible result.
Is transparency kept?
Yes. Transparent and semi-transparent areas are kept as they are.
What size will the AVIF be?
SVG files have no fixed pixel size. By default we render the SVG at its own width and height; choose 2× or 4× scale, or type an exact width, for a larger and sharper AVIF.
Why does AVIF take longer than other formats?
AVIF squeezes images much harder than JPG or WebP, and that takes more computing power — typically one to a few seconds per photo, a bit more on phones.
Can I convert several SVG images at once?
Yes. The free plan handles 10 images at a time, and you can download everything as a single ZIP. Pro removes the batch limit, converts files in parallel and supports files up to 4 GB.
Are my files uploaded to a server?
No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any up-to-date browser — Chrome, Edge, Safari, Firefox or Samsung Internet — on phones, tablets and computers, with nothing to install. On phones, extremely large images may be scaled down to fit within the browser’s memory limit; you will see a note if that happens.
