Convert uploads to next-gen WebP and AVIF on the fly — smaller files, faster pages, zero manual work.
Lighter images across your whole library, with no quality you will notice.
Automatically serve modern formats that cut image weight dramatically.
Convert new uploads instantly and batch-convert your existing library.
Older browsers still get a compatible image — nothing breaks.
Enable the converter and pick your target formats and quality.
New uploads convert automatically; run a bulk pass on old media.
Visitors get smaller, faster images with no extra effort.
Yes. New uploads convert automatically, and a bulk tool processes the existing Media Library in the background in batches, so a large library doesn’t tie up a single request or time out.
Either, or both. Choosing Both keeps WebP as the primary file with an AVIF sibling alongside it. Quality is set separately per format, defaulting to 82 for WebP and 55 for AVIF, so you can tune each codec on its own terms.
Yes, as long as Keep backup is on — it is by default. WordPress core’s untouched original is retained, so a conversion can be reversed. There is also a Lossless option that re-encodes from that kept original when you can’t afford any quality loss.
No. JPEG and PNG are converted by default, but GIF is deliberately off, because converting an animated GIF would flatten it and lose the animation. You can enable it if you know your GIFs are static.
Yes. Max width caps the stored dimension in pixels; leaving it at 0 uses WordPress’s own 2560px “big image” threshold.
Only with care, which is why WordPress blocks them by default — an SVG is XML and can carry scripts, event handlers and external references, making it a stored-XSS vector. The setting here restricts SVG upload to administrators who can already publish unfiltered HTML; editors and authors still cannot upload one even while it is on.
