Image weight is one of the biggest reasons web pages load slowly. WebP typically stores the same photo 25–35% smaller than JPG, and every current browser supports it. pdfty's JPG to WebP converter is a quick way to prepare hero images, product photos and blog illustrations so your site scores better on Core Web Vitals and loads faster on mobile.
We convert on our server with Pillow at quality 85, which keeps photos looking clean while cutting size. EXIF rotation from phone photos is applied, so nothing ends up sideways on your page. WebP is widely supported online, but some desktop software and older apps still cannot open it — keep your JPG originals for those.
Upload a whole folder of images and get a ZIP with one WebP per file. Free: no daily limit, up to 20 MB per file, no watermark, no sign-up. Files are deleted within 1 hour. For the best page-speed gains, resize oversized photos to the width your layout actually uses before converting.
Drag and drop one or several .jpg files. Up to 20 MB each free.
Each image is re-encoded as WebP at quality 85, rotated upright from EXIF.
One file gives one .webp; several files arrive as a ZIP.
Replace the JPGs in your CMS or use them in a <picture> element.
Your files are deleted from our servers within 1 hour.
