Renames 18 ambiguous or hard-to-search tool names so image tools self-qualify like the other modalities ("Compress" becomes "Compress Image"), and cleans up a few awkward names. Propagated across search (constants.ts), display (en.ts + 20 locales), the OpenAPI base spec + 20 locale specs, and the docs tool-page headings in 21 languages. Removes the duplicate "Normalize Audio" summary shared by the video and audio endpoints. Tool ids and routes are unchanged, so no API paths or bookmarks break.

|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/audio.mp3",

|
## Notes {#notes}
|
|
|
|
- Positive values increase volume; negative values decrease it.
|
|
- Large positive gains can cause clipping. Use normalize-audio for loudness-safe leveling.
|
|
- Output usually keeps the input container. AAC input is written as M4A, and unsupported decode-only inputs fall back to MP3.
