WebP savings: transparency and compatibility first
`convert-webp-smaller` often replaces JPEG/PNG at similar visuals, but legacy Safari builds, some mail clients, and embedded WebViews still need JPEG/PNG fallbacks. Transparent WebP plus CMS rounded masks can fringe. When AVIF/WebP/JPEG coexist, document `<picture>` or negotiation order so marketing tests on Chrome do not ship broken iOS experiences.
Recommended steps for WebP compression
- In `convert-webp-smaller`, confirm the browser matrix and whether `<picture>` or alternate sources are required.
- Check transparent art on dark and light plates; ensure list thumbnails are not over-denoised.
- Log lossy versus lossless and quality; validate magic bytes in CI so extensions cannot lie about MIME.
WebP compression Q&A
Rolling WebP sitewide—what three decisions come first?
Fallback strategy, lossy versus lossless, and alpha handling—then align quality and longest edge.
Files are smaller yet Lighthouse still flags huge images—why?
You may still be serving JPEG on critical paths, or `srcset` may ship desktop widths to phones—verify MIME and decoded pixels in DevTools.
Occasional broken images after CMS bulk import—how to trace?
CI-check headers versus extensions; store export commands and source hashes in the DAM for diffs.
Before publishing `convert-webp-smaller` assets externally, which compliance checks are mandatory beyond visual quality?
Start with "define size thresholds explicitly", "match platform upload rules", and "sample on real destinations", then explicitly verify "alpha transition artifacts" and "batch naming collisions" before release approval.
Under deadline pressure, how should teams balance speed and stability in `convert-webp-smaller` processing?
Start with "normalize naming conventions", "run channel dry-runs", and "retain source/output evidence", then explicitly verify "detail loss after compression" and "CDN fallback inconsistency" before release approval.
