Free WebP Converter – Convert JPEG & PNG to WebP Online
What is the Free WebP Converter
The Free WebP Converter converts and resizes images right in your browser: JPEG, PNG, WebP, and AVIF in — WebP, JPG, or PNG out. Everything runs client-side, so nothing gets uploaded anywhere. WebP is Google’s image format, and it cuts file size by 25–35% versus JPEG and PNG at the same visual quality.
How the converter works
Pick your images, choose the output format (WebP, JPG, or PNG) and optionally a resize width, set the quality with the slider (0–100%, default 80%), and click Convert. It all happens in your browser through the HTML5 Canvas API, so your images never reach a server.
Instant conversion in your browser
Conversions happen locally in your browser, with no server round-trip, so results show up right away.
100% private and secure
No image is sent to a server. Everything stays on your device, so your data stays private.
Batch conversion, up to 50 images
Convert multiple images at once, not one at a time: up to 25 per batch without an account, up to 50 with a free account.
Full quality control
The quality slider (0–100%) lets you balance visual quality against file size. 80% is the recommended default.
What you can do with the Free WebP Converter
Reduce image size with no quality loss
WebP shrinks file size by 25–35% at the same visual quality, so pages load faster and use less data.
Resize to the exact width you need
Presets 1920 / 1280 / 800 px or any custom width, aspect ratio kept. Phone photos become web-ready images in one pass: resized AND converted.
EXIF metadata stripped automatically
Re-encoding removes EXIF metadata automatically, including the GPS location in phone photos. You publish the image, not where you took it.
Flexible download — single or batch
1 image → download directly as `.webp`; 2+ images → get a ZIP with all conversions.
Optimize for web and mobile
WebP is Google’s recommendation for fast mobile-first results. Your website images will load faster everywhere.
Compatible with 97% of browsers
WebP is supported by Chrome, Firefox, Safari, Edge, and Opera. Unlike AVIF, there are no compatibility concerns.
Free, with or without an account
No account gets you 30 free conversions a day. With a free account, conversions become unlimited and batches grow to 50 images.
Benefits of using WebP
WebP is the image format Google recommends for fast, mobile-first sites. Convert your images to WebP and your pages send less data and load faster, which helps your mobile SEO without any extra work on your side.
