Image Converter

Convert any image to JPEG, PNG, WebP, or AVIF, entirely in your browser. Your image never leaves your device, there's no server upload, just your browser's own image encoder.

Why use our Image Converter

Modern formats cut page weight

WebP and AVIF are 25-50% smaller than JPEG at equivalent quality, smaller images mean faster load times and better Core Web Vitals scores.

Automatic fallback if unsupported

If your browser can't encode AVIF, we automatically fall back to WebP, then JPEG, so you always get a real result instead of a failed conversion.

100% local, nothing uploaded

Conversion happens in your browser's own canvas engine, your image is never sent to any server, ours or anyone else's.

Metadata stripped automatically

Re-encoding through canvas drops EXIF and GPS data as a side effect, your converted image carries no camera or location metadata.

Frequently Asked Questions

Is my image uploaded to a server?
No. Conversion happens entirely in your browser using the native canvas API. Your image never leaves your device, we have no way to see it.
Why isn't AVIF working for me?
Not every browser can encode AVIF via canvas yet, notably older Safari versions. When that happens, we automatically fall back to WebP, then JPEG, so you still get a smaller file.
Will converting to WebP or AVIF hurt image quality?
At the quality level we use, the difference is imperceptible for photos. WebP and AVIF are more efficient codecs, they achieve the same visual quality at a smaller file size, not lower quality at the same size.
Does this work for bulk/multiple images?
This tool processes one image at a time. For site-wide image optimization across every page, that's part of SEOMentor's dashboard Image SEO tools.
