AVIF is built on the AV1 video codec's intra-frame compression, which is significantly more efficient than the decades-old compression scheme JPG still uses. In practical terms, AVIF files are often 30 to 50 percent smaller than a JPG of comparable visual quality, which is why major websites have adopted it for product photos, hero images, and other content where load speed directly affects user experience and search ranking. AVIF also supports transparency and higher bit depths, two things JPG cannot do at all.
The tradeoff is encoding time and compatibility: AVIF encoding takes more processing time than JPG, and while all major modern browsers now support displaying AVIF, very old browsers and some legacy software may not, which is worth checking against your specific audience before fully replacing JPG with AVIF.
- Install Turbo Batch Image Converter Pro on your Windows PC.
- Open the app and select Batch Mode for multiple files, or Individual Mode for a single JPG.
- Drag your JPG file or folder into the app window, enabling recursive folder scanning if needed.
- Set the "From" format to JPG and the "To" format to AVIF.
- Adjust the quality setting to balance file size against visual detail for your use case.
- Click Convert. AVIF files are written to your output folder, fully offline.
- 100% offline — your photos are never sent to any server
- Bulk conversion of entire folders, including sub-folders, in one pass
- Multi-core processing scales up to 32 concurrent workers, helping offset AVIF's heavier encoding cost
- Optional batch resizing during the same conversion step
- Option to delete original JPG files automatically once converted
- No recurring subscription or hidden upload limits
How much smaller is AVIF compared to JPG?
It varies by image content, but AVIF commonly produces files 30 to 50 percent smaller than a JPG at similar visual quality, thanks to its more modern compression algorithm.
Do all browsers support AVIF?
All current major browsers support displaying AVIF images, though very old browser versions may not, so checking your specific audience's browser usage is worthwhile before fully switching formats.
Does AVIF conversion take longer than converting to JPG or PNG?
Yes, AVIF encoding is more computationally intensive than older formats, but multi-core batch processing helps keep total conversion time reasonable for large folders.
