Why attachments bounce in Outlook
Mail systems apply a limit to the whole message, not to each file. Encoding an attachment for email also adds roughly a third to its size, so a set of files that looks comfortably under the limit can still be rejected.
Fit Files Into One Email works this out for you. We look at every file together, share the compression across them and leave a safety margin for the message itself. You just see "Ready to send together".
Your files stay separate
We never merge your attachments and we never zip them automatically. Four files go in and four files come out — smaller, still individually named, and ready to attach.
What you never have to choose
Bitrate, codec, DPI, resolution, sample rate or image quality percentage. You pick a size; we do the rest.
