About MP4 files

MP4 (MPEG-4 Part 14) is a widely used digital video container format that stores video, audio, subtitles, and metadata in a single file. It supports efficient compression (e.g., H.264/AVC or H.265/HEVC) while maintaining good quality, making it ideal for streaming, downloads, and sharing. MP4 is highly compatible with most devices, media players, and online platforms (e.g., YouTube, smartphones) due to its standardized structure. Though less flexible than MKV, it balances quality, file size, and universal playback support. We can also convert MP4 files to animated images (e.g., GIF , WEBP , APNG)

About ALAC files

ALAC (Apple Lossless Audio Codec) is a lossless audio format developed by Apple, designed to compress audio files without sacrificing sound quality. It maintains the full fidelity of the original recording while reducing file sizes, making it ideal for music archiving and high-fidelity listening. ALAC is natively supported on Apple devices and iTunes, though it can also be played on other platforms with compatible software. While similar to FLAC in quality, ALAC is optimized for Apple's ecosystem and is a popular choice for users within that environment who want lossless audio without the larger file sizes of uncompressed formats like WAV.

Batch Convert MP4 to ALAC Online

With this convertor, you can easily convert multiple MP4 files to ALAC format directly in your browser — completely free. You can also customize the video resolution (width and height) during the conversion.

To access advanced settings, click the Options button in the top right corner. There, you can set the output size for your ALAC files.

Additional Settings:

Video Size: Set the width and height for the output ALAC file.

Encoding Speed:Controls how fast the video is encoded. Faster speeds may result in larger file sizes.

Video Bitrate:Set between 1–10,000 Kbps to control the video quality and file size.

Frame Rate:Defines the video’s FPS (frames per second). Higher frame rates produce larger files.

Audio Bitrate:Recommended range is 16–320 Kbps.

Cut Video: Trim the video using a start and end time in HH:MM:SS format. For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the video or animation.

Before converting, you can choose a folder on your device where the converted ALAC files will be saved. Each MP4 file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
