Frequently asked questions
How do I convert M4A to FLAC?+
Upload your M4A file (or drag it onto the box above), wait a few seconds while StandardsPDF converts it in your browser, then download the FLAC. There is nothing to install and no account required.
Is converting M4A to FLAC free?+
Yes. M4A to FLAC conversion is free on the StandardsPDF free tier – no watermark, no signup, and no credit card. A Pro tier lifts the file-size and daily limits if you need more.
Will the FLAC keep the quality of my M4A?+
StandardsPDF aims for the highest fidelity the FLAC format allows, so your audio file comes through looking as close to the original as possible. Some format-specific details may adapt where FLAC works differently to M4A.
Can I choose the bitrate when converting M4A to FLAC?+
On the free tier StandardsPDF picks a clean default bitrate for your FLAC; Pro lets you set the exact bitrate and sample rate for the M4A to FLAC conversion.
What is the maximum M4A file size I can convert to FLAC?+
Up to 100 MB per M4A on the free tier and 2 GB on Pro. If your M4A is larger, split it first or upgrade for the higher limit.
