   Pro Tips for Maintaining Extra Quality

   1. Never double-compress. If your ZIP is already compressed, expanding to a folder and re-zipping with "Store" resets quality.
   2. Use SHA-256 checksums. Before conversion, record the hash of your assets. After conversion, unzip the SB3 and compare hashes. They should match exactly.
   3. Batch rename correctly. Changing .sb3 to .zip and back does not affect quality—only recompression does.
   4. Beware of cloud storage. Downloading a ZIP from Google Drive or Dropbox sometimes alters binary blobs. Always verify file size.
