When to use this MP4 converter

  • Fix compatibility issues — if a video won't play on your iPhone, Android device, or smart TV, converting it to MP4 (H.264) guarantees playback.
  • Prepare for social media — platforms like Instagram, TikTok, and Twitter recommend or require MP4 format for seamless uploading and processing.
  • Standardize video formats — unify a collection of varied video files (MKV, WebM, MOV) into a single, consistent format for editing or archiving.
  • Remove black bars — use the built-in auto-crop feature to detect and remove letterboxing during the conversion process.

We also have dedicated converters for 3GP to MP4, MKV to MP4, WebM to MP4, and MOV to MP4. If you need an open, web-optimized format instead, try our Video to WebM converter.

Frequently asked questions

Is this video to MP4 converter free?

Yes, 100% free with no watermarks, no signup, and no conversion limits. All uploaded files are automatically deleted from our servers one hour after upload to protect your privacy.

What codecs are used for the output MP4?

This tool encodes the video stream using H.264 (AVC) and the audio stream using AAC. This specific combination within an MP4 container provides the absolute best compatibility across all modern devices, browsers, and operating systems.

Does converting to MP4 reduce video quality?

Since we encode using standard H.264 compression, there may be a slight, usually imperceptible, loss in quality if the original video was uncompressed or used a different codec. However, the tool is optimized to maintain high visual fidelity while ensuring the output is compatible and efficient.

Can I crop the video while converting?

Yes. Before clicking "Convert!", you can select a target aspect ratio (like 16:9, 1:1, or 9:16) from the "Crop video" dropdown. You can also select "Auto remove black bars" and the tool will automatically detect and crop out letterboxing.
