This tool re-encodes JPG and JPEG photos as WebP, the format most websites now serve to browsers. The main reason to do it is file size: at comparable visual quality, a WebP version of a photo typically comes out 25 to 35 percent smaller than the JPG it came from. On a page with one image that barely matters. Across a product catalog or a photo-heavy blog, it adds up to real bandwidth.
JPG and lossy WebP both throw away image data to save space, so this conversion re-compresses a photo that has already been compressed once. At the default quality of 85 the second pass is hard to spot on ordinary photos, but it is not reversible. Keep your original JPGs somewhere. If you ever need to edit or reprint the photo, go back to the source file rather than the WebP.
The slider defaults to 85, which is a sensible compromise for photographs. Going above 90 grows the file quickly for detail most people cannot see. Dropping below 70 starts to smudge fine texture such as hair, grass and fabric, and faces are usually where viewers notice first. If you are converting images for a site, run one representative photo at two or three settings, compare them at full size, then process the rest of the batch at the value you settled on.
The converter writes a clean WebP without copying EXIF data, so camera settings, capture date and GPS coordinates from the original JPG do not travel into the output. For photos headed to a public website that is usually a feature, not a loss. If you rely on embedded copyright fields or color profiles, note that those are stripped as well, which can slightly shift colors in wide-gamut images.
You can queue as many as 30 JPGs in a single job, as long as the whole upload stays under 50MB. Every file in the batch uses the same quality setting. A single converted image downloads directly; two or more arrive as one ZIP archive. Uploads and results are deleted from the server automatically, roughly ten minutes after the job finishes.
Every current browser handles WebP, so for web use you rarely need a fallback anymore. The holdouts are elsewhere: older versions of Microsoft Office, some desktop email clients and a number of print services still reject WebP uploads. If the image is going into a document or off to a print shop, JPG remains the safer format.
Drag up to 30 JPG or JPEG files into the upload box, keeping the total under 50MB.
Leave the slider at 85 for most photos, or raise it toward 90 when fine detail like faces and texture matters.
Start the job and wait a moment while each photo is re-encoded as WebP on the server.
Save the single WebP file, or the ZIP archive if you converted more than one image.
For typical photos, expect the WebP to be roughly a quarter to a third smaller than the JPG at the default quality. The exact saving depends on the image; heavily detailed photos shrink less, and a JPG that was already compressed very aggressively may barely shrink at all.
Slightly, because both formats are lossy and the conversion re-encodes the image. At quality 85 the change is rarely visible on normal photos. Keep the original JPG if the image matters, since the process cannot be reversed.
No. The output WebP carries no EXIF, so capture date, camera model and GPS location are removed. That is usually desirable for images going on a public website, but do not rely on this tool to preserve embedded copyright fields.
WebP has shipped in every major browser for years, including Safari since 2020, so a fallback is rarely needed now. The exceptions are mostly non-browser software such as older Office versions and some desktop email clients.
Each file is converted separately at the quality you chose, and the results are delivered together in a ZIP archive. A job can hold 30 images as long as the upload totals no more than 50MB.
