Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Keep the total around 10 MB
  • Set image size to around 1600px
  • With many photos, split across emails

Phone photos can be 3–8 MB each, so a few reach an email limit.

Steps

  1. In "Compress & Resize Images", choose all the photos you want to send.
  2. Set size to "1600px" and quality to "Normal".
  3. Tap "Compress" and save as a ZIP or one by one.
  4. Attach the saved images to your email.
