WEBP, explained.
Compact images for the web, with transparency.
Web delivery or an upload form?
WebP is a raster image format useful for web assets that need photographic detail or transparent edges. A destination can still require JPG or PNG even if your browser displays WebP. Check the accepted formats before converting; a smaller file in the wrong format will still be rejected.
WebP compared with JPG and PNG
JPG does not retain transparency. PNG is useful for sharp diagrams and avoiding another lossy encode of decoded pixels. The WebP format supports different compression modes, but FormatPlease offers browser-encoded still WebP with a quality setting, not a guaranteed lossless switch. Compare actual downloads at the dimensions you need; no format is always smaller.
Animation and existing compression
Animated WebP input exports a still frame with a warning; this tool does not preserve its motion or frame timing. A lossy source may already lack detail. Converting it to PNG does not restore that detail, and lowering WebP quality again can add visible artifacts.
A practical workflow
- Open the WebP converter hub and choose a conversion your destination accepts.
- Check the source preview, alpha edges and any animation warning; choose quality or dimensions where available.
- Inspect the downloaded image on light and dark backgrounds, compare its bytes and keep the original.
What you can do here
- Input: supported.
- Output: supported.
- Transparency in output: supported.
- Quality control: adjustable from 1 to 100.
GIF offers first/all frame extraction. TIFF supports all/selected pages; PDF renders selected pages separately. Other animated sources export a still frame with a warning. EXIF metadata is removed from converted images.
Common questions
Why does a website reject my WebP?
The uploader may accept only specified formats or dimensions. Use a JPG or PNG conversion when the destination requires it; renaming the extension does not convert the file.
Can I keep a transparent WebP background in JPG?
No. JPG output fills transparent pixels with your selected background, white by default. Choose PNG if alpha is required.
