Convert JPG photos to WebP for a smaller web-ready file, with adjustable quality and local browser processing.
Convert JPG to WebP in your browser with adjustable quality and a clear before-and-after size comparison.
WebP uses a newer image codec than JPEG and can often represent photographic detail more efficiently. The exact result depends on the image and the quality setting, so the most useful number is the size comparison shown after your conversion.
Use a higher value for images with text overlays, fine texture or sharp edges. Lower values shrink the file more aggressively but can introduce softness or visible compression artifacts. Start high, check the result, then step down only if you need a smaller file.
Compressing a JPG keeps the same format and applies another round of JPEG compression. Converting to WebP changes the codec itself, which can produce a smaller file at a similar visual quality. If the destination cannot accept WebP, compress the original JPG instead.
Toolmera decodes the image into the browser canvas and creates a new WebP file from the pixels. Camera metadata such as EXIF fields and GPS data is not copied into that new output file.
Choose files or drag and drop them into the tool. You can queue up to four images in one batch.
Review the output settings, then run the conversion locally in your browser.
Compare the before-and-after size and download the converted files you need.
Useful next steps in the same workflow.
There is no fixed percentage. It depends on the photo and the quality setting, so Toolmera shows the actual before-and-after size for your file.
Start toward the higher end for photographs with fine detail, then reduce the value while checking whether the visual result still looks acceptable.
The current browser-canvas workflow creates a fresh WebP from the decoded pixels and does not copy the original EXIF metadata.
Modern browsers support WebP, but a specific older application or upload platform may still require JPG or PNG.
