Convert Image to WebP

Add one or more photos below — WebP is already selected as the output format. WebP typically produces smaller files than JPEG or PNG at a similar visual quality, which is why it's become the default for a lot of the web.

Everything runs on-device: your photos are never uploaded anywhere. Compress, resize, crop, or watermark in the same pass, then download each file or the whole batch as a ZIP.

Batch-compress, resize, crop, rotate, watermark, and convert formats — right in this tab.

JPEG · PNG · WebP · AVIF (where supported) — your photos never leave this browser tab

No photos yet

Nothing here yet — add photos above to get started.

Only helps if your background is already one plain color (e.g. a wall) — this is color-distance math, not real subject cutout, so it won't do anything useful against busy or textured backgrounds.

You'll crop it to the exact aspect ratio next.

Frequently asked questions

What is WebP and why use it?

WebP is a modern image format that typically produces smaller files than JPEG or PNG at similar visual quality, which is why most browsers and websites use it by default now for faster page loads.

Will every website accept WebP?

Nearly all modern browsers support it, but a few older tools, forms, and legacy systems still expect JPG or PNG — check the destination before relying on WebP for something like a government form.

Does WebP support transparency?

Yes, similarly to PNG, while typically producing smaller files.

Can I convert a batch of mixed formats to WebP at once?

Yes — add photos in any supported format (JPG, PNG, HEIC, and more) and they'll all convert to WebP in the same pass.
