Pitfalls to avoid

Edge halos at low quality

Aggressive compression can create fringing around transparent edges. Check logos and cutouts on light and dark backgrounds.

Assuming WebP is always lossless

Depending on quality settings, conversion may be lossy. Keep source PNG files for future design revisions.

Breaking old platform pipelines

Some older CMS plugins and email tools still reject WebP uploads. Validate destination support before bulk replacement.
