Frequently Asked Questions

Will compressing M4A reduce quality?
Our compressor uses smart bitrate allocation to minimise visible quality loss. For most files, the difference is imperceptible at normal viewing sizes.
Can I compress M4A to exactly 1MB?
Yes. Our tool targets 1MB as the maximum output size, adjusting encoding parameters to get as close as possible without exceeding it.
Is M4A compression free?
Yes, completely free. No account, no watermarks, no limits on how many files you compress.
What compression settings should I use?
The default settings work well for most use cases. If you need a specific size, enter it in the target size field and the tool will handle the rest.
Is it safe to upload my M4A file?
All uploads are encrypted with HTTPS and your files are deleted from our servers immediately after the compressed version is ready for download.
