Frequently Asked Questions

What video format does YouTube recommend?

YouTube recommends MP4 with H.264 video encoding and AAC audio. This combination offers the best compatibility and the fastest post-upload processing time.

What resolution should I upload to YouTube?

Always upload your highest available resolution. YouTube supports up to 8K. Common uploads are 1080p (1920×1080) and 4K (3840×2160). Higher resolution triggers HDR processing for better quality in the final stream.

What aspect ratio does YouTube use?

YouTube's player is 16:9 widescreen. Uploading 16:9 fills the player with no bars. Shorts require 9:16 vertical. Use our Video Cropper to change aspect ratio before converting.

Will converting to MP4 affect quality?

Re-encoding involves some generation loss. For best results, keep your source at the highest original quality. If your source is already H.264 MP4, the format conversion step is minimal.

Is my video kept private?

Yes. Your file is processed privately and automatically deleted within 60 minutes. We never store or analyse your content.
