Committing to a lossy format's compression level sight unseen is a gamble, since the same quality setting that looks fine on one photo can visibly degrade a different one, and confirming that tradeoff actually requires seeing the compressed result sitting right next to the original before deciding it's acceptable. This tool converts an image between JPEG, PNG, WebP, and AVIF in any direction, with a quality slider and a side-by-side preview showing exactly what a given setting does before committing to it.

Useful for comparing how the same photo compresses across several different formats before picking one, dialing in a JPEG or WebP quality level while watching the visible tradeoff update live, or converting between any pair of these formats without needing a separate single-purpose tool for each direction.

Quick answers for Image Format Converter

Which formats can I convert between?
JPEG, PNG, WebP, and AVIF as output formats, with JPEG, PNG, WebP, AVIF, and GIF all accepted as input.
Why is the quality slider disabled for PNG?
PNG is a lossless format, so there is no quality setting to adjust, it always encodes at full fidelity regardless of the slider position.
Can I compare the file size before and after converting?
Yes, the Before and After panels show each version's file size side by side, plus a percentage showing how much smaller or larger the converted file turned out.
