Стиснення з втратами vs без втрат — простий посібник

Lossy formats (MP3, JPG, AAC, H.264) discard data to shrink files. Lossless formats (FLAC, PNG, WAV, ZIP) keep all data but produce larger files.

Rule: only convert lossy → lossless when you must — you won't recover lost quality. Convert lossy → lossy only once — each re-conversion degrades the result.
