Compress Image for Email

Make images smaller for email attachments.

Use case

Make image attachments easier to send and receive

Email problems are often caused by several large camera photos rather than one unusually large file.

Compress the batch to a practical attachment size, then make sure the recipient's mail service and the final image dimensions still match the purpose of the photos.

  • Keep individual images comfortably below the email provider limit.
  • Use JPG for broad compatibility with photo attachments.
  • Resize very large camera originals before applying heavier compression.

FAQ

Can every image become 100KB?

Most can be made smaller, but detailed photos may need smaller dimensions or visible quality tradeoffs.

Is WEBP always smaller?

WEBP is often efficient, but some upload forms only accept JPG or PNG.

Why does compression make text blurry?

Text and sharp edges show artifacts sooner than normal photo areas. Resize first and avoid excessive compression.

Should I use target size or automatic mode?

Use automatic mode for general sharing. Use target size when a form lists a hard maximum.
