⛓️ Recipe — 3 steps, listed below, all in your browser.

The exact steps

  1. Decode each picture
  2. Limit the longest side to 640 px
  3. Encode WebP at 75% quality

One thumbnail per source; download them together as a ZIP.

Why this chain

Small preview slots do not need full-resolution source files. The resize keeps the visual dimensions appropriate for cards and listings.

Honest limits

These are screen previews, not print masters. Animated sources contribute their first frame only. Keep the original files for later editing.
