How It Works
Convert JPG to WebP in three simple steps
Upload JPG Files
Drop your JPG or JPEG images onto the upload area. Any JPG is supported — camera photos, website images, design exports. Upload up to 20 files with 100 MB combined on the free plan.
Set WebP Quality
Choose WebP quality from 40 (aggressive) to 100 (lossless). Quality 80 is recommended — identical visual quality to JPG quality 85 at 25–35% smaller file size. Choose encoding method 4 (balanced) for the best speed/compression trade-off.
Download WebP Files
Get WebP files ready to drop into your website, CMS, or image CDN. WebP is supported by Chrome, Firefox, Edge, Safari, and all modern browsers. Multiple files download as a ZIP.
JPG to WebP Features
Smaller files, faster pages, better Core Web Vitals scores
Up to 35% Smaller Than JPG
WebP uses a more advanced compression algorithm than JPEG. At the same perceived visual quality, WebP files are typically 25–35% smaller than their JPG equivalents. This directly reduces page load times, bandwidth costs, and improves Google Lighthouse / Core Web Vitals scores for image-heavy pages.
Quality 40–100 + Lossless
Six quality presets from 40 (very compact) to a true lossless mode that preserves every pixel. Quality 80 is the recommended starting point — it produces WebP files with no perceptible quality difference from JPG quality 85 while being meaningfully smaller. Lossless mode is suitable for source files and assets you'll edit further.
Batch Convert 20 Files
Upload and convert up to 20 JPG files at once. All files are converted simultaneously and delivered as a ZIP archive. Ideal for converting a whole image gallery or a folder of product photos to WebP for a web optimisation project.
Encoding Method Control
WebP encoding method (0–6) controls the speed/quality trade-off of the encoder. Method 4 (balanced) is the default — it takes a moderate amount of CPU time and produces near-optimal compression. Method 6 produces the smallest possible output at the given quality but takes longer. Method 0 is fastest but produces larger files.
97%+ Browser Support
WebP is supported by Chrome, Firefox, Edge, Safari (since 2020), and all major mobile browsers — covering over 97% of global web users. For the small percentage using older browsers, serve JPG as a fallback using the HTML <picture> element with a WebP <source> and a JPG <img> fallback.
100% Private & Secure
All uploads use TLS 1.3 encryption. Images are processed in isolated server containers and permanently deleted within 24 hours. No watermarks are added. We never view, index, or share your files.

Frequently Asked Questions
WebP files are 25–35% smaller than JPG at the same perceived visual quality. Smaller images load faster, use less bandwidth, and improve Google's Core Web Vitals scores (particularly Largest Contentful Paint). Google's Page Experience ranking signal rewards fast-loading pages. Converting your site's images to WebP is one of the most impactful and easiest performance optimisations for image-heavy websites.
WebP is supported by 97%+ of global web users as of 2024. Supported by: Chrome (since 2010), Firefox (since 2019), Edge (since 2018), and Safari (since 2020). Not supported by: Internet Explorer (end-of-life), very old mobile browsers. For maximum compatibility, serve WebP to browsers that support it and JPG as a fallback using the HTML <picture> element.
Quality 80 is the recommended starting point for most web images — it produces WebP files that look identical to JPG quality 85 on all standard displays while being 25–35% smaller. Use quality 90 for product photography where fine detail matters (e-commerce). Use quality 70 for thumbnails, previews, and images where file size is critical. Use lossless mode only for source files or assets you'll further edit — lossless WebP is larger than JPG.
Use the HTML <picture> element to serve WebP to supporting browsers with JPG as fallback: <picture><source srcset="image.webp" type="image/webp"><img src="image.jpg" alt="..."></picture>. Alternatively, most modern CMS platforms (WordPress, Shopify, Webflow) automatically serve WebP to capable browsers if you upload WebP files or enable an image optimisation plugin.
The WebP encoding method (0–6) controls how much effort the encoder puts into finding the optimal compression. Method 0 encodes very quickly but produces larger files; method 6 tries harder and produces the smallest possible file at the given quality, but takes more CPU time. Method 4 (default) is the best practical balance — it achieves ~95% of the compression of method 6 in roughly 30% of the time.
