01Plan for attachment limits, not guesses
A 25 MB target gives the encoder a clear budget. For personal Gmail accounts, Google currently documents a 25 MB attachment limit, although mail systems and organization policies can differ. If you need extra room for other attachments, choose a smaller custom target.
02Leave room for a quality-friendly resolution
FitMyVideo estimates how much video bitrate remains after audio and container overhead. If a long 1080p clip would have too little bitrate, Auto mode can step down to 720p or 480p rather than keeping unnecessary pixels.
03Use the dedicated email workflow when needed
If your goal is specifically email, the Email Video Compressor explains attachment considerations and starts with the same editable 25 MB baseline.
04Private browser processing
The selected video is processed locally in the supported browser workflow, so FitMyVideo does not need a cloud upload step or a server-side media library.
