How to Convert Images to WebP
Upload Your Images
Click "Choose Images" or drag and drop files into the upload area. Supports JPG, PNG, GIF, BMP, AVIF, SVG, TIFF and more. Select multiple files at once for batch conversion.
Choose Compression Mode
Use Auto Smart mode for best automatic results (targets 50–100 KB), or switch to Manual mode to set your own target size from 10 KB to 100 KB using the slider.
Download Your WebP Files
Click the green "Download WebP" button next to each file, or use "Download All" to save everything at once. No waiting, no email, no sign-up required.
The Smart Format for the Modern Web
Faster Page Load Speed
WebP images are 25–35% smaller than JPG and up to 50% smaller than PNG at the same visual quality — meaning faster websites and happier visitors.
Better SEO & Core Web Vitals
Google rewards fast pages. Switching to WebP directly improves your LCP (Largest Contentful Paint) score and overall Page Experience ranking signals.
Lower Hosting Bandwidth
Smaller image files reduce your monthly bandwidth usage — saving real money on hosting, CDN, and storage costs for high-traffic websites.
Supported Everywhere
WebP is supported in all modern browsers — Chrome, Firefox, Safari, Edge — and all mobile browsers. It is Google's recommended format for the web.
Supports Transparency
Unlike JPG, WebP supports alpha transparency — making it a perfect replacement for PNG files used in logos, icons, and layered web graphics.
100% Private Processing
All conversion happens inside your browser using the Canvas API. Your images are never uploaded to any server. No data is stored or tracked.

Frequently Asked Questions
Is this WebP converter completely free?
Yes, 100% free — always. No registration, no payment, no hidden limits, and absolutely no watermarks, ever.
Do my images get uploaded to a server?
No. All conversion happens locally inside your browser using the HTML5 Canvas API. Your images never leave your device. This makes the tool ideal for sensitive images such as ID cards, personal photos, and business documents.
Which image formats are supported?
Supported formats include JPG, JPEG, PNG, GIF, BMP, AVIF, SVG, JFIF, ICO, TIFF, and WEBP (re-optimization). The output is always high-quality WebP format.
Is WebP better than JPG or PNG?
For web use, yes. WebP provides 25–35% smaller files than JPG at equivalent quality, and up to 50% smaller than PNG. It also supports transparency (like PNG) and animation (like GIF). All major modern browsers support WebP fully.
Can I convert multiple images at once?
Yes. Select multiple files or drag and drop them all at once. Each image is processed independently, and you can download them individually or all at once using the "Download All" button.
Is there a file size limit?
There is no server-side limit since we do not use any server. The only limit is your device's available RAM. Modern devices handle even large high-resolution images with ease.
How does manual size control work?
Switch to "Manual" mode in the Compression Settings panel, then use the slider to set your desired target output size from 10 KB to 100 KB. The tool will automatically adjust WebP quality and resolution scaling to hit your target as closely as possible.
Does it work on mobile phones?
Yes. The tool works perfectly on Android, iPhone, iPad, and all modern mobile browsers. The entire interface is touch-optimized and fully responsive.
