Image Compressor For Email

Most inboxes reject or clip large attachments — our Image Compressor shrinks images so they attach cleanly and load fast for whoever opens your email.

Use Cases

  • Attaching a photo without hitting your email provider's size limit

  • Compressing an inline image so a newsletter loads quickly

  • Preparing a signature logo that displays reliably across email clients

  • Sending multiple photos in one email without a slow, bulky attachment

Tips & Best Practices

  • Most providers cap total attachment size around 25MB — compress before you hit that wall
  • Inline images in HTML emails should stay small so they don't slow down open rates
  • JPEG works reliably across every email client; some older ones mishandle WebP
  • A compressed logo in your signature loads instantly instead of showing a broken icon
