Shrink JPGs to WebP for faster page loads and smaller hosting bills - modern, free, browser-only.
Converting JPG to WebP cuts image file sizes by 25-35% at the same perceived quality. For a site that serves a lot of images - product galleries, photo blogs, news sites - that's a measurable hit to bandwidth bills and page load times. Every modern browser plays WebP natively, including Safari 14+, so the compatibility cost is essentially zero on today's web.
We decode the JPG and re-encode as WebP at Q=92, which is the visually-lossless sweet spot. The output retains every detail of the source JPG while shipping smaller bytes. JPG's original lossy losses are baked in (we can't recover what the JPG encoder discarded), but no further loss is added in WebP terms. Everything happens locally; no upload.
JPG (JPEG) is the dominant lossy image format on the web - small files, near-universal support, but no transparency. Best for photos and high-frequency detail.
WebP is Google's modern image format that beats both JPG and PNG on file size at the same quality. Supports transparency and animation, plays in every recent browser.
Drag a JPG onto the converter above, or click the box to pick one from your device.
We've preselected WebP as the output format. Change it from the dropdown if you want a different target.
Click Convert and wait for the progress bar to finish. Download the WebP when it's ready.
Shrink PNG files to WebP without losing transparency - smaller files, same quality, every modern browser.
Save a WebP image as a JPG so it opens in older software and uploads to legacy systems.
Convert JPG to PNG for editing, archiving, or when you need a lossless copy.
