how to convert jpg to webp
Drop your JPG file
Drag your JPG file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs Canvas API on your device to decode the JPEG and encode it as WebP. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the WEBP file
When the conversion finishes, the WEBP file is ready to download. Save it anywhere on your device.
FAQ
common questions
Will my JPG file lose quality when converted to WEBP?
Yes, slightly. Both JPEG and WebP are lossy — the converter has to decode the original and re-encode into WEBP, which adds a second generation of compression artefacts on top of whatever was already in the JPG. The difference is usually invisible at normal viewing sizes for one round-trip, but the file you end up with is materially noisier than a single direct encode.
What happens to transparency when converting JPG to WEBP?
WebP supports an alpha channel, but JPEG doesn't carry one — there's no transparency information in your JPG for the WEBP to preserve. The output will be fully opaque unless you add transparency later in an editor.
Does WEBP keep the EXIF / camera metadata from my JPG?
Both JPEG and WebP can carry EXIF metadata (camera, lens, date, GPS), so the converter preserves it. If your source JPG was tagged with GPS coordinates from a phone, those coordinates travel with the file into the WEBP.
Will an animated JPG convert to an animated WEBP?
WebP supports animation, but a still JPG only has one frame to start with. The output is a single-frame WEBP — still rather than animated.
Will the WEBP file be smaller or larger than my JPG?
Roughly the same. The two formats have comparable compression characteristics, so file size doesn't change dramatically — exact ratio depends on content and encoder settings.
When does it make sense to convert JPG to WEBP?
Common reasons: JPG is lossy — every re-save reduces quality, while WEBP is typically 25–35% smaller than JPEG at similar quality. Converting also matters when the app, device, or platform you're sharing with prefers WebP — all modern browsers and most current image apps; older desktop apps may need a plugin.
Where will my WEBP file open after conversion?
All modern browsers and most current image apps; older desktop apps may need a plugin. WebP is widely enough supported that you can hand the output file to most modern apps and expect them to render it.
Does this site upload my JPG files anywhere?
No. The whole conversion runs in your browser using Canvas API. The file you drop in never leaves your device — we don't see it, and we couldn't even if we wanted to.
Is there a file size limit for JPG to WEBP?
There's no hard cap — limit is your device's memory. Several hundred megabytes works fine on a typical laptop. Phones and low-RAM machines may struggle with very large files.
Does JPG to WEBP work offline?
Once this page has loaded, yes. The converter library lives in your browser and runs without any further network calls. Reloading the page does still need connectivity.
