JPG to WEBP Converter
Convert JPG photos to WEBP and typically cut file size by a quarter to a third at the same visual quality. Upload an image below, set the quality if you want, and download a web-optimized WEBP.
WEBP is Google's modern image format and is supported by every current browser. Smaller images mean faster page loads — one of the simplest performance wins available for a website.
How the JPG to WEBP conversion works
Filembly decodes your JPG and re-encodes it with the WEBP encoder in libvips at your chosen quality (default 85). WEBP's compression is simply more efficient than JPEG's 1992-era algorithm, so the same visual quality fits in fewer bytes. EXIF metadata is stripped and orientation is baked into the pixels.
How to convert JPG to WEBP
- Upload your .jpg image above.
- Confirm WEBP as the destination; adjust the quality slider if needed.
- Click Convert.
- Download your smaller WEBP file.
Limitations to know about
- A handful of older tools and apps still don't open WEBP files — notably some desktop photo editors and older email clients. Every modern browser supports it.
- Converting a JPG to WEBP re-compresses an already-compressed image; at very low quality settings the two generations of loss can compound. Stick to quality 75+ for photos.
Privacy and security
Your file is uploaded over HTTPS, converted entirely in memory and streamed straight back to your browser. It is never written to disk, never logged and never retained after the conversion — there is nothing to delete because nothing is stored. Files are validated by extension, type and content signature, and uploads are never executed. Read more in our privacy policy.
Frequently asked questions
How much smaller will a WEBP be than my JPG?
Typically 25–35% smaller at equivalent visual quality, though it varies by image. Detailed, noisy photos benefit less; smooth images with gradients benefit more.
Do all browsers support WEBP?
Yes — Chrome, Firefox, Safari, Edge and all modern mobile browsers have supported WEBP for years. The stragglers today are certain desktop applications and legacy systems, not browsers.
Should I use WEBP for every image on my site?
For content images, generally yes. Keep a JPG or PNG fallback only if you must support very old software. For images that need transparency, WEBP replaces PNG at a fraction of the size.
