What is the difference between WebP and AVIF?

Both are modern compressed formats. AVIF generally achieves better compression (smaller files) than WebP at equivalent quality, but AVIF encoding is slower and browser support, while good, is slightly less universal than WebP.

Will converting JPG to PNG improve quality?

No. Converting a JPG to PNG only changes the container format. The original JPG compression artifacts are already baked in and cannot be recovered by re-encoding to PNG.

What is the maximum file size I can convert?

There is no hard server-side limit because processing is local. In practice, very large images (over 20 MB) may slow down older devices due to browser memory constraints.

Does PNG support transparency?

Yes. PNG supports full alpha-channel transparency, which is why it's preferred for logos and icons. JPG does not support transparency — transparent pixels become white when saved as JPG.
