什麼是 MP3 格式？

MP3 is a lossy audio format that shrinks music and speech files while keeping acceptable quality for headphones and speakers. It remains the most compatible audio format worldwide.

為什麼要把 MP3 轉為 M4A？

MP3 and M4A serve different roles in file workflows. Converting between them can make a file fit a particular editor, browser, upload form, archive, or delivery step, but the result should always be checked because layout, metadata, transparency, animation, or compression can change.

使用建議

Keep the original file until the output opens correctly in the application or service where it will be used. For images and media, compare dimensions, playback, transparency, and visible quality. For documents and data, check text encoding, page layout, delimiters, and special characters.

隱私與安全

Supported local conversions use browser processing and download APIs, so the selected file does not need to be sent to a conversion server. Browser memory and device capability still affect large jobs. Read the processing notice on the page before using sensitive material.
