How to batch convert videos to MP4 on Mac

Updated 2026-07-10 · Runs locally — nothing uploaded

Quick answer

Drop every source file together, choose MP4 once and confirm; FFmix creates a visible command and a separate local queue job for each video.

Output: One compatible MP4 per source
Processing: On your Mac
Setup: About 2 minutes to queue
Access: Free local task

Batch conversion should not mean writing a shell loop or feeding files to a website one at a time. Drop the whole set into FFmix, apply Anything → MP4, and confirm once. MOV from an iPhone, MKV from an archive and WebM from a browser capture can all enter the same queue.

FFmix still preserves transparency: each item has its own literal command, progress and result. Free users get an unlimited serial queue; Pro can run three jobs in parallel. Outputs are named from their sources and saved beside them, so a bulk job never silently replaces the original media.

Steps

1 Drop all the source videos into FFmix at once.
2 Select the files, choose Convert format and set MP4 as the output.
3 Review the shared settings and the per-file command before running.
4 Confirm once; FFmix queues one local job per file and saves each result beside its source.

Advanced: canonical ffmpeg recipe

This is the canonical recipe. FFmix adapts encoder flags to the engine on your Mac, then shows the final command; the command shown is the command run.

ffmpeg -i "input.mov" -c:v libx264 -crf 18 -preset medium -c:a aac "input-converted.mp4"

FFmix has a one-click "Anything → MP4" preset

Drop a file and go — all local, nothing uploaded.

FAQ

Can FFmix batch convert mixed input formats?

Yes. MOV, MKV, WebM and AVI files can share the same MP4 output settings; each file becomes its own queue job.

Will batch conversion overwrite my source videos?

No. FFmix uses a suffix and automatically numbers conflicts, so the originals remain untouched.

Does the free version support multiple files?

Yes. Local tasks and file counts are unlimited; the free queue processes one job at a time, while Pro adds parallel slots.
