⚠ Filenames must match exactly — e.g. 17846.png replaces every asset named 17846.png in the playable. Case-insensitive. Extension must match. For DW-IMG inner assets, look for the 📂 dw_NNNNNN.png badge in the scanner above — that is the exact filename to use.
If filenames don't match, a + assign button appears per file — click it to manually pick which playable asset(s) to replace.

Re-encodes every data:image/*;base64,… URI in the playable. PNG keeps alpha (no JPEG conversion for transparent images), JPEG is recompressed at the chosen quality. Runs entirely in your browser — no upload.
