What is JPG?
JPG (JPEG) is the most widely supported photo format. Its lossy compression is tuned for photographs, so files are small and open everywhere — but it can't store transparency, and every re-save loses a little detail.
What is AVIF?
AVIF is based on the AV1 video codec. It is often the smallest of the common image formats at a similar quality and supports transparency, but encoding is slower and many desktop apps can't open it yet.
What changes when you convert JPG to AVIF
Both formats are lossy, so the picture or sound is re-encoded once more; at the default quality the difference is hard to notice. Expect a smaller file than the JPG in most cases.
Does converting JPG to AVIF reduce quality?
Slightly: both are lossy, so the JPG is re-encoded. At the default setting most people can't see or hear a difference; raise the quality setting if you need more headroom.
Will the AVIF be smaller than the JPG?
Usually, yes — AVIF typically stores the same content in less space. The result screen shows the before and after sizes.
Can I convert several JPG files at once?
Yes — up to 100 files of 100 MB each in one go. Several results download together as a ZIP.
Are my images safe?
Yes. Your images are only used to create your result — they’re never shared and never used to train AI.
