This tool converts WEBM to ALAC completely free and without any functional limitations. Since it is based on the browser API, the processing speed is the fastest because all files are processed locally on your device and are not uploaded to our server.
Batch Convert WEBM to ALAC Online
With this convertor, you can easily convert multiple WEBM 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 WEBM file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all WEBM files are converted, click
Save All to instantly save all ALAC files to your selected folder.
About WEBM files
WebM is an open, royalty-free video format designed for web use. It supports efficient VP9/AV1 video compression and Opus/Vorbis audio, offering high quality with small file sizes. Ideal for HTML5 streaming, WebM works seamlessly in browsers like Chrome and Firefox, making it a top choice for online videos and web apps.
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.
