Image format conversion
Convert JPG to WebP
Re-encode a JPG as WebP without uploading anything. Load the image, switch the export format to WebP, set the quality while the live estimate shows the resulting file size, and download — the conversion runs entirely in your browser.
Why convert a JPG to WebP at all?
JPG has been the default web image format for decades, and it works — but WebP usually produces a visibly identical image at a noticeably smaller size. For anything you publish online, that difference compounds: pages load faster, visitors on metered connections download less, and image-heavy layouts stop being the slowest part of the page. The picture itself does not change; the encoding around it does.
WebP also keeps what JPG cannot: transparency. If a JPG ever came from a cut-out with the background baked in, going back to a WebP workflow means transparency is an option again for future edits.
How the conversion works here
There is no separate convert mode — the editor converts at export. Load your JPG, leave the crop alone if you only want a format change, then pick WebP in the format selector beside the preview. The quality slider behaves the same way it does for JPG: drag it and the live MB estimate updates, so you can see exactly what each quality level costs. Press download and the file saves with the editor's usual name-width×height pattern.
A sensible routine: start at the same visual quality you had, note the MB estimate, then step the slider down until the size stops justifying the trade. WebP generally tolerates lower quality settings before artifacts show, so give it a step or two more than you would give a JPG.
Common questions
Will every browser display my WebP?
All current major browsers — Chrome, Edge, Firefox, Safari — display WebP. Very old browsers and some niche apps may not, so for archives or files you send to unknown software, keeping a JPG copy alongside the WebP is a reasonable habit.
Is my file uploaded anywhere?
No. The image is read from your device, re-encoded in the browser's own memory, and saved straight back. Nothing is transmitted.
Should I convert PNG to WebP too?
If the PNG is a photo-like image and size matters, often yes — WebP handles both transparency and photographs. For hard-edged graphics where PNG is already small, compare the estimates and keep whichever wins. The editor's format selector makes that a ten-second experiment per image.
