tl;drDrop photos below — each JPG is compressed to fit email attachment caps. Gmail tops at 25 MB total per email; Outlook at 20 MB. Apple Mail and Yahoo allow 25 MB. Browser-only, no upload.
Email providers split into two camps: 25 MB total per email (Gmail, Yahoo, Apple Mail, iCloud) and 20 MB (Outlook, Office 365). The cap counts the entire email, not per-attachment, so 5 photos at 5 MB each will fit Gmail but not Outlook.
Pick the 20 MB chip if you're emailing across providers — it's the safe lower bound. Pick 25 MB if you know the recipient is on Gmail.
For HEIC iPhone photos, this is also a format-conversion step: most desktop email clients still don't render HEIC inline. The output JPEG works everywhere.
Common questions
What's the actual Gmail attachment limit?
25 MB total for the entire email. Above that, Gmail offers a Google Drive link instead. Outlook is 20 MB.
If I send 5 photos at 5 MB each, will it work?
25 MB total exactly — Gmail accepts. Outlook rejects (20 MB cap). Compress each to 4 MB to be safe across both.
Why is my iPhone photo rejected by Outlook?
HEIC format isn't recognised by Outlook's preview pipeline. Convert to JPEG first — that fixes it.
