Frequently Asked Questions
Does SeerKits upload my video to a server?
SeerKits prefers local processing in your browser whenever your device supports the conversion. For heavier codecs, a secure server path may be used — we never store your file after the job finishes, and no account is required.
What is the free file size limit?
You can convert video files up to 200 MB for free on the web. Need larger files, batch conversion, or custom bitrate controls? Download Seer Video from the Seer app ecosystem for expanded limits.
Which output format should I choose?
MP4 (H.264) offers the widest compatibility for sharing and playback. WebM is great for web embeds with smaller sizes. Choose MOV if you are editing in Apple-centric workflows.
