What does converting JPEG to AVIF mean?
JPEG is a lossy format optimized for photographs (identical to JPG), while AVIF is a next-generation format based on the AV1 video codec offering the best compression of any mainstream image format. AVIF achieves even smaller files than WebP or JPEG — the next step up in compression efficiency.
JPEG — the same format as JPG under a different file extension — uses lossy compression tuned to human perception, producing small files ideal for photographs at the cost of some fine detail and no transparency support.
AVIF routinely produces files 50% smaller than JPG at the same visual quality, and supports transparency and a wide color range. Browser support is strong in all current major browsers, though very old software may not display it.

When to convert JPEG to AVIF
Preparing JPEG files for high-performance websites that need the smallest possible images
Convert JPEG images to AVIF when your project specifically calls for high-performance websites that need the smallest possible images.
Reducing file size
If AVIF compresses better than JPEG for your content, converting can significantly cut storage and bandwidth needs.
Improving compatibility
Some platforms and software only accept certain formats — converting to AVIF ensures your JPEG files open everywhere they need to.
Batch migrating a library
Convert a whole folder of JPEG images to AVIF at once instead of opening each file individually in an editor.

Frequently Asked Questions
Will converting JPEG to AVIF reduce image quality?
The converter uses a high-quality output setting by default, so any quality loss when converting to AVIF is minimal and generally not visible to the eye.
Does AVIF support transparency?
Yes, AVIF supports transparency, so any transparent areas in your JPEG file are preserved in the converted image.
Is it safe to convert my images here?
Yes. All conversion happens locally in your browser using the Canvas API — your files are never uploaded to a server.
Can I convert multiple files at once?
Yes, drop several files at once and click Convert All — every file is processed and can be downloaded individually or as a ZIP.
Is there a file size limit?
There is no hard limit set by Pixvert, but very large files depend on your device's available memory to process smoothly.
Can I use the converted images commercially?
Yes, Pixvert only changes the file format — it does not alter your rights over the image or add any watermark.
