WebP Merger
Combine WebP images into one. Free, in-browser. No upload.
WebP supports both lossy and lossless compression and transparency. Merging WebP images is useful when your assets are already WebP—common for web and Android. You get one combined image that stays efficient for web use. The tool runs in your browser.
When to use WebP Merger vs other formats
Use WebP when you're building for the web or want smaller file sizes with good quality. Merge WebP when your sources are WebP to avoid format conversion. Use PNG when you need maximum compatibility with older tools. Use JPG when you don't need transparency and want universal support.
Compatibility
WebP is supported in all modern browsers and Android. Older browsers and some desktop apps may not support it; convert to PNG or JPG if you need universal compatibility.
Quality considerations
WebP can be lossy or lossless. Merging preserves the format; choose quality settings when exporting. WebP often gives smaller files than PNG at similar quality.
Example use cases
- Merge WebP assets for web pages or PWAs into one image.
- Combine WebP photos or graphics for a gallery or landing page.
- Create a single WebP from multiple icons or thumbnails.
- Build comparison or collage in WebP for fast loading.
