Common Problems and Solutions

Problem: WebP images not displaying

Solution: Check browser support—WebP works in Chrome, Firefox, Safari 14+, and Edge. For older Safari, provide JPG/PNG fallback using the <picture> element.

Problem: WebP file is larger than original

Solution: This can happen with already-compressed JPGs or very simple images. Try lowering quality setting, or stick with the original format if it's already optimized.

Problem: Can't edit WebP in Photoshop

Solution: Convert to PNG for editing using our WebP to PNG converter. Edit your PNG, then convert back to WebP when done.

Problem: WebP transparency looks wrong

Solution: Ensure you're using a quality setting of 100% for lossless transparency, or 90%+ for minimal artifacts around transparent edges.

Problem: Animated WebP not playing

Solution: Some older software doesn't support animated WebP. Convert to GIF for maximum compatibility (though files will be larger).
