MP4 file info

Upload an MP4 file and see its full technical profile — codec, resolution, frame rate, bitrate, and tags — without uploading it anywhere.

Same extension, very different files

An .mp4 can hold H.264 or HEVC or AV1 video, AAC or MP3 audio, at any resolution and frame rate. This inspector reads your file’s actual composition, which is what determines where it plays and how it edits.

Frequently asked questions

Why does my MP4 fail on an older smart TV?

Often HEVC video: newer phones record it by default, older TVs decode only H.264. The codec field here confirms it in one look.

Can I see the audio details too?

Yes, audio codec, channels, and sample rate are part of the readout.

Local analysis?

Yes, the file never leaves your device.
