Convert JPG to WebP
Free, private, and instant — your files never leave your device.
JPEG has been the web's standard photo format for thirty years, but WebP typically achieves 25–34% smaller files at equivalent perceptual quality using more advanced compression algorithms. Converting your JPEGs to WebP is one of the highest-impact optimizations for web performance: smaller files mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores. Both formats are lossy, so re-encoding will apply another round of compression — use a high quality setting (85%+) to keep the added loss imperceptible.
JPEG
Joint Photographic Experts Group
- Lossy compression
- No transparency
- Best for: photographs, social media images, email attachments
WebP
Web Picture format
- Lossy compression
- Supports transparency
- Best for: web images, CMS uploads, app assets
How to Use
- 1
Drop your JPG file — the output format is already set to WebP.
- 2
Set the quality level. 80–85% is a common balance for web images; use 90%+ when fidelity matters, such as for product or portfolio photography.
- 3
Click "Convert to WebP" — conversion runs in your browser.
- 4
Download the WebP and upload it to your web server or CMS. Modern browsers display WebP natively.
Frequently Asked Questions
How much smaller will the WebP be than the JPG?
Typically 25–34% smaller at equivalent visual quality. Images with smooth gradients and natural scenes see the largest savings; highly detailed images or those already saved at low JPEG quality see less reduction.
Does re-encoding from JPG to WebP reduce quality further?
Yes — both are lossy formats, so re-encoding applies compression on top of the existing JPEG compression. At quality settings of 85%+ the additional degradation is minimal and usually imperceptible. Avoid very low quality settings to prevent compounding artifacts.
Do all browsers support WebP?
All modern browsers do: Chrome 23+ (2012), Firefox 65+ (2019), Edge 18+ (2018), and Safari 14+ (2020). If you need to support older browsers, use the HTML <picture> element with a WebP source and a JPEG fallback.
Can I replace all my site's JPEGs with WebP?
For images served to browsers, yes — with the <picture> fallback pattern for safety. For downloadable images, email attachments, or offline use, JPEG remains more broadly compatible. Check whether your image CDN or CMS can serve WebP automatically before converting your entire library.
