What is SVG?
SVG is a vector format: instead of pixels it stores shapes, lines and text as code, so it stays perfectly sharp at any size. That makes it ideal for logos and icons on websites. Many apps, social networks, document editors and printers do not accept SVG files, which is why people convert SVG to PNG or JPG at a chosen size.
What is AVIF?
AVIF is the newest mainstream image format, based on the AV1 video codec. It often makes files 30–50% smaller than JPG and noticeably smaller than WEBP at the same visual quality, with support for transparency, HDR and wide colour. Modern browsers display AVIF, but many desktop apps, older phones and upload forms still cannot open it.
When should you convert SVG to AVIF?
- Hero images and banners on modern websites
- Image-heavy apps where every kilobyte counts
- Next-generation e-commerce catalogues
- Testing the best possible compression
Tips for the best AVIF results
- For websites, 75–85% quality is usually the best balance between size and sharpness.
- Choose a larger width (for example 2000 px) if the image will be printed or shown on large screens.
- You can convert many SVG files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original SVG files until you have checked the converted AVIF images.
