What is a .ACD file?
Everything worth knowing about ACID Pro Project File.
An ACD file is an ACID Pro project file - a DAW session that stores track layout, effects, and references to external audio loops, but not the audio itself. Open it with ACID Pro or ACID Music Studio (Windows only, both from MAGIX). If the project plays silence or shows missing files, the referenced loop files need to be in the same folder structure as when the project was saved.

Is my .ACD file uploaded to a server?
No. Your .ACD file is converted for you. The converted file is created in memory,.
Why is conversion slower than desktop software?
Browsers give web pages a single CPU core for this kind of work and no hardware video encoder. Short clips convert in seconds; for long 4K films a desktop app like HandBrake is faster. Use Start and Length to convert just the part you need.
Which output format should I pick?
MP4 plays on every phone, TV and browser. WEBM is an open format that's great for the web. MP3 keeps only the sound. MKV (no re-encode) is instant and lossless, but only changes the container.
Can I keep all audio tracks and subtitles?
The MKV (no re-encode) option copies every track as-is. MP4 and WEBM keep the first video and audio track, which is what most players use.
Why can't some files be converted?
Files protected with DRM (for example purchased iTunes .m4p songs or some .wmv rentals) are encrypted. We can show what's inside, but nobody can convert them without the key.
