Why uploads get rejected

Websites and social apps only accept certain formats, file sizes and dimensions. A video in MKV or WEBM, a HEIC photo or a file that is too large is often refused. Converting to the format the platform expects — usually MP4 for video, JPG or PNG for images and MP3 for audio — solves most upload errors.

Safe defaults for most platforms

Video: MP4 with H.264 video and AAC audio, 1080p or 720p. Images: JPG for photos, PNG for graphics with text or transparency. Audio: MP3 at 192 kbps or higher. Check the platform’s current size limit and compress the file if it is still too big.

Prepare media for an upload

Upload services can limit accepted formats, dimensions and file sizes. Start with the service requirements, select an available output option and review the converted file before publishing it.
