Why WebP?
- Compare actual output sizes; WebP can reduce image payload for some images.
- WebP supports alpha transparency.
- WebP supports animation, but this converter exports a single rendered frame.
- Current browser encoding support varies; the converter retains a PNG fallback.
- A smaller output can reduce transfer time when used by the destination.

WebP conversion notes
- Lossy mode uses the original browser encoder with a quality setting from 10% to 100%.
- Lossless mode uses a WebP encoder in a worker to preserve the rendered image pixels.
- If WebP encoding is unavailable, the converter exports an actual PNG with the correct filename.
- Existing alpha transparency is retained. Metadata and animation are not preserved by Canvas conversion.
- All image processing stays in your browser; image bytes are not uploaded.
About Convert to WebP
Our free WebP converter converts supported images to WebP. Output size depends on image content, compression mode and quality. Compare the reported size and preview before replacing a file. For compatible destinations, converting images to WebP is one of the most effective steps you can take.
WebP supports lossy and lossless compression and alpha transparency. This converter produces a single rendered frame, including from GIF input, and does not preserve animation. The image to WebP converter gives you full control over compression quality and lossless mode selection.
Web developers use it to cut image weight before a Core Web Vitals audit, and bloggers use it to shrink JPG and PNG files before they reach a CMS media library. Your images are never uploaded to any server.
Key Features
- Convert JPG, PNG, GIF (first frame), and BMP images to WebP format
- Lossy compression with adjustable quality slider (10% to 100%)
- Lossless compression option for pixel-perfect conversions
- Real-time file size comparison showing exact reduction percentage
- Side-by-side preview of original and converted images
- Drag-and-drop or click-to-upload file input
- Automatic fallback to PNG if the browser does not support WebP encoding
- One-click download of the converted file
- Images are never uploaded to a server
- Images up to 20 MB, with no watermark on the output
How to Convert Images to WebP
- Upload your image: Click the upload area or drag and drop a JPG, PNG, GIF, or BMP file.
- Choose compression mode: Leave lossless unchecked for maximum size savings, or enable it for pixel-perfect quality.
- Adjust quality: If using lossy compression, drag the quality slider to balance file size and visual quality.
- Convert: Click "Convert to WebP" and the converted image appears instantly.
- Review results: Compare the original and converted images side by side and check the file-size reduction percentage.
- Download: Click "Download WebP Image" to save the optimized file to your device.
Use Cases
- Website optimization: Replace heavy JPEG and PNG files with WebP to dramatically speed up page loads and improve Core Web Vitals scores.
- E-commerce stores: Convert thousands of product images to WebP for a faster shopping experience and lower hosting costs.
- SEO improvement: Smaller suitable files can reduce image transfer time. Format alone does not guarantee better search ranking.
- Blog & content sites: Reduce image payload for posts with many photos, improving time-to-interactive for readers.
- Mobile web apps: Serve lighter images to save bandwidth and improve performance on cellular connections.
- Digital advertising: Create smaller ad creatives that load faster and reduce ad-serving costs.
- Email newsletters: Smaller inline images mean faster email rendering and fewer clipped messages.
Frequently Asked Questions
What is the difference between lossy and lossless WebP?
Lossy WebP reduces file size by discarding some image data, similar to JPEG. Lossless WebP preserves every pixel exactly, similar to PNG, resulting in larger files but perfect quality.
Do all browsers support WebP?
Current major browsers support WebP display, but encoding capability varies. This tool exports PNG when WebP encoding is unavailable. Check the destination’s format support.
Does WebP support transparency?
Yes. WebP supports alpha-channel transparency in both lossy and lossless modes, making it an excellent replacement for transparent PNG images.
How much smaller are WebP files compared to JPEG?
Size depends on the image and encoder settings. Published comparisons describe specific datasets, not a guaranteed saving for your file. Compare the actual output size.
Tips & Best Practices
- Use lossy mode for photos: Photographs compress extremely well with lossy WebP at 75-85% quality, delivering major size savings with minimal visible loss.
- Use lossless for graphics: Logos, icons, screenshots, and illustrations with flat colors benefit from lossless WebP compression.
- Serve WebP with fallbacks: Use the HTML
<picture>element to serve WebP to supporting browsers and JPEG/PNG to others. - Test quality settings: Compare the original and converted images side by side to find the lowest quality setting that still looks great.
- Convert in bulk for websites: Convert all existing site images to WebP and update your templates for an instant performance boost.
- Check file size reduction: Compare actual size and preview quality. Choose the format that fits your destination; a fixed saving percentage is not required.
