Convert Images to WebP
WebP files are often noticeably smaller than JPG or PNG at similar visual quality, which makes pages load faster. Drop in a batch of images and you'll see the original size, the new size and the percentage saved for each one.
Images are converted on your device and never uploaded.
Your files and text are processed only in this browser. Nothing is uploaded or stored on a server.
How to use
- Drop up to 20 JPG or PNG images (25 MB each).
- Adjust the quality slider (default 80).
- Compare original and WebP sizes.
- Download images one by one or all together as a ZIP.
Features and limits
- GIF (first frame only), BMP and AVIF are also accepted when your browser can decode them.
- Transparency in PNG files is preserved in the WebP output.
- Each image can be up to 16.7 megapixels.
- In browsers that can't encode WebP natively, such as Safari, a built-in WebAssembly encoder takes over automatically.
- EXIF metadata, including GPS location, is not copied to the converted files.
FAQ
Does converting to WebP reduce image quality?
WebP at these settings is lossy, so lower quality values mean smaller files and more visible artifacts. The default of 80 is a common starting point; compare the result and adjust if needed.
Why is my WebP file larger than the original?
Already heavily compressed JPGs or simple PNGs with few colors can grow when re-encoded. Try a lower quality value, or keep the original for that image.
Does it work in Safari on iPhone or Mac?
Yes. Safari can't create WebP through the canvas, so the tool switches to its built-in encoder.
Will an animated GIF stay animated?
No. Only the first frame of a GIF is converted, producing a still WebP image.
