Your .aac file is decoded and written out as lossless FLAC. From here on, edits and conversions add zero further quality loss, and the file gains proper support for tags and album art, which raw AAC streams lack entirely.
FLAC cannot reach back in time: detail discarded by the original AAC encode stays gone. The point of this conversion is stopping the bleeding, not healing it.
Raw .aac files typically come out of radio stream recorders, broadcast pipelines, and some voice recorders. They are awkward citizens: many editors will not open them and there is nowhere to write a title or artist.
Converting to FLAC turns them into well-behaved archive files that any serious audio tool accepts and that carry checksums against silent corruption.
No. It preserves the current quality exactly and prevents any future degradation. Improvement is not possible once data has been discarded by a lossy encoder.
Raw ADTS streams have no standard tag container. After converting to FLAC you can add full metadata with the audio metadata tools.
No. Everything runs in your browser. The file never leaves your device.
