SVG to AVIF Converter
To convert SVG to AVIF, add your SVG files, type an output width or leave it empty for the built-in size, and press Convert. The drawing is rendered to pixels in your browser and encoded as AVIF at 60% quality by default, keeping transparency. AVIF encoding is slower than other formats. Nothing is uploaded; the SVG stays on your device.
- Free, no sign-up
- Your file never leaves your device
- Up to 50 MB per file
Your file never leaves your device; images are processed in your browser. EXIF and location data are not added to the output.
How to convert SVG to AVIF
Add your SVG files
Drag the images onto the upload area or browse for them; you can add several files at once.
Keep AVIF as the output
AVIF is already selected. For formats with a quality setting the slider starts at a default that suits the format (JPG 90%, WebP 80%, AVIF 60%); lower it if you want a smaller file.
Convert and download
Press “Convert”. Every file is processed in your browser, and you can download the results one by one or as a ZIP.
What is preserved?
Kept
- The image resolution (pixel dimensions)
- The correct photo orientation (EXIF orientation is applied)
- Colors (adapted to sRGB)
- Transparency (alpha channel)
Changed
- AVIF is a lossy format: lower quality means a smaller file but less fine detail
- The lossless source is recompressed at the quality you choose, so pixel values are no longer identical
- The vector drawing becomes pixels; the output is fixed at the chosen size
Not carried over
- EXIF, location and camera data: left out of the output for privacy
- Infinite scalability: the raster output turns pixelated when enlarged
When to use it
Large illustrations for fast pages
Complex SVG illustrations with many paths can be slow to draw on phones. A pre-rendered AVIF at the display width is often lighter and quicker to show.
Images for platforms without SVG support
Some apps and content systems accept AVIF but refuse SVG. Rendering once lets you use the artwork there at a small file size.
Limitations to know
- External images and fonts referenced by the SVG are not loaded; text may be drawn with a system font.
- Up to 50 MB per file; the output can be at most 16,384 pixels on one side.
- On iPhone and iPad, images above roughly 16 megapixels may not be processed because of a browser limit.
About the formats
What is SVG?
SVG describes an image with shapes, paths and text in XML instead of pixels, so it stays sharp at any size. It is ideal for logos, icons and illustrations. When a program or website needs a pixel image, an SVG is rendered into a raster format such as PNG at a chosen size.
What is AVIF?
AVIF is a modern image format based on the AV1 video codec. It delivers very small files at high visual quality, supports transparency, HDR and animation, and is among the most efficient formats for the web. Encoding is slower than for other formats, and some older software cannot open AVIF yet.
Frequently asked questions
When is AVIF better than keeping the SVG?
When the SVG is very detailed, uses heavy filters or cannot be uploaded. For simple logos and icons, the original SVG is usually smaller and sharper at every size.
Does a large output width make AVIF slow?
Yes. Encoding time grows with the number of pixels, so a 4000 pixel wide render takes noticeably longer than a 1000 pixel one.
Why do some parts of my SVG not appear?
Linked images and web fonts referenced from outside the SVG file are not loaded. Embed them in the SVG or convert text to outlines first.
Is converting SVG to AVIF free?
Yes, completely free. There is no account, subscription or watermark; just add your files and convert them.
Are my files uploaded anywhere?
No. Images are processed in your browser and never leave your device, so the waiting time depends on the file size and your device. EXIF and location data are not added to the output.
