How to Reduce Image File Size for Email Attachments
Email bouncing back because attachments are too large? Compress images first.
Gmail limits attachments around 25 MB total; Outlook has similar caps. A few RAW or uncompressed photos can exceed that instantly. Compression makes sharing feasible.
Target sizes for email
- Under 1 MB per photo for comfortable sending
- JPEG quality 70–80% is usually fine for viewing
- Resize down if dimensions exceed 2000px
- Zip multiple files after compressing
