원본 형식
FLAC compresses audio without discarding decoded sample data.
FLAC
FLAC (Free Lossless Audio Codec) is a lossless audio format that compresses music and recordings without removing any audio data. It keeps the original sound quality intact while usually using much less storage than uncompressed WAV. FLAC is popular for music libraries, archiving, hi-fi playback, and converting to other audio formats later.
AAC
AAC is a file format supported by Convertr for online file conversion workflows.
What happens when FLAC becomes AAC
목표 포맷
AAC is a lossy audio codec that is efficient at moderate bitrates.
어떤 변화가
Audio samples are decoded from FLAC and encoded according to the AAC format and selected bitrate or quality.
- 무엇이 보존되는가
- Duration and audible content are preserved, subject to decoder support and any settings you change.
- What may be lost
- Tags, embedded artwork, chapters, and codec-specific metadata may not map to AAC.
- Codec and quality implications
- AAC uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the FLAC source.
- Realistic limitations
- Protected audio, malformed headers, unsupported codec variants, or files without a decodable audio stream cannot be converted.
변환 단계
- Upload a FLAC file no larger than 1 GB.
- Confirm that AAC is selected as the target.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the AAC file and check the result before deleting your source.
문제 해결
- The FLAC file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The AAC file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- The result has no sound or will not play.
- Try a broadly supported target codec and verify that the source contains a decodable audio stream.
개인 정보 보호 및 파일 보존
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
