JPG to WebP Converter
Convert JPG photos into lighter WebP files for faster web pages. Drop as many images as you like — nothing is uploaded.
About this tool
Google created WebP specifically to replace JPG on the web: it stores photographs at 25–34% smaller sizes than JPG at equivalent quality, which translates directly into faster page loads, lower bandwidth bills and better PageSpeed scores. This free tool converts JPG/JPEG photos to WebP right in your browser — ideal before uploading product photos, blog images or portfolio shots to a website.
The converter re-encodes each photo with the browser's built-in WebP encoder at a quality level chosen for the web, so the result looks identical to the eye while weighing noticeably less. Batch conversion is automatic: every JPG you drop is processed in turn and can be downloaded individually or together. Your photos are never uploaded — everything runs on your own device, which also makes it fast on large batches.

Frequently asked questions
Why convert JPG to WebP?
Smaller files at the same visual quality. WebP's smarter compression typically cuts 25–34% off a JPG's size, so pages load faster and score better on speed tests — a ranking factor for search engines and a conversion factor for shops.
Will I lose quality converting JPG to WebP?
Both formats are lossy, so there is a second encode, but at the quality used here the difference is not visible in normal viewing. For archival originals keep the JPG; for anything shown on a website, WebP is the better delivery format.
Can I convert WebP back to JPG later?
Yes — use our WebP to JPG converter. Keep in mind that each lossy re-encode discards a little more detail, so it's best to convert from your original JPG rather than round-tripping repeatedly.
Do social networks and email accept WebP?
Most platforms (WordPress, Shopify, Facebook, Twitter/X) accept WebP uploads, but some email clients and older apps don't display it. Use WebP for your website and keep JPG for sharing by email or with older software.
Are my photos uploaded anywhere?
No. The conversion happens entirely in your browser — files never leave your computer, and there is no limit on how many you convert at once.
