What Size Should Photos Be for Email?
It depends on the purpose:
- Casual photos to friends/family: 500KB–1MB is fine and looks great
- Professional photos to clients: 1–2MB maintains quality for viewing on screen
- ID or document photos: Under 240KB for most official forms
- Product photos for buyers: 500KB–1MB, JPEG format
Why Not Just Use Google Drive or Dropbox?
Cloud links work, but many recipients prefer direct attachments — especially for official correspondence, job applications, and business emails. Compressing the image directly is simpler and more professional.
Privacy: Is It Safe to Compress Photos Online?
With most online tools, your photos are uploaded to a server — which means someone else has access to your images. Our tool works differently: all compression happens in your browser. Your photos never leave your device.
Compress Multiple Photos at Once
Sending a photo album or event photos? Drop up to 10 images at once and they all compress simultaneously. No waiting, no queue — all processed locally in seconds.
