AVIF is a modern image format that delivers noticeably smaller file sizes than JPG at a comparable visual quality, thanks to more efficient compression derived from the AV1 video codec. For websites, this means faster page loads and lower bandwidth use, which is why AVIF has become a popular target format for web images, product photos, and any situation where file size directly affects performance.
The catch is that AVIF encoding can be slow if done one image at a time, and most online converters require uploading your files first. Converting a batch of JPGs to AVIF locally avoids both issues, processing your images directly on your own computer.
- Download and install Turbo Batch Image Converter Pro on your Windows PC.
- Open the app and switch to Batch Mode for multiple files, or Individual Mode for a single JPG.
- Drag and drop 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. Your 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 for faster batch jobs
- Optional batch resizing during the same conversion step
- Option to delete original JPG files automatically once converted
- No recurring subscription or hidden upload limits
Is AVIF better than JPG for web use?
For most web use cases, yes — AVIF typically produces smaller files at similar visual quality, which helps page load speed, though browser support should be checked if your audience uses older browsers.
Can I convert an entire folder of JPGs to AVIF at once?
Yes, Batch Mode handles entire folders, including nested sub-folders, and scales conversion speed across multiple CPU cores.
Does AVIF conversion take longer than converting to JPG or PNG?
AVIF encoding can be more computationally intensive than simpler formats, but multi-core processing helps keep batch conversion times reasonable.
