Compress Images for Email — Free, Fast & Private

Email providers like Gmail, Outlook, and Yahoo limit attachments to 10-25MB. High-resolution phone photos at 5-15MB each means you can only attach 1-2 photos before hitting the limit. MiniPx compresses your images to email-friendly sizes in seconds.

The ideal size for email images is 100-300KB at 1280px width. This looks great on any screen while keeping total email size manageable. The Smart preset at 1280px width produces exactly this range.

All processing happens in your browser — your photos are never uploaded to any server, making MiniPx safe for personal and confidential images.

How it works

  1. Upload your photos: Add the images you want to email.
  2. Select Smart preset: Smart compression gives the best balance of quality and size for email.
  3. Set max width to 1280px: This produces ideal dimensions for viewing on screen.
  4. Download and attach: Save compressed images and attach to your email.

Frequently asked questions

What size should email images be?
For email attachments, 100-300KB per image at 1280px width is ideal. This keeps total email size under limits while looking sharp on any device.
Why are my emails bouncing due to size?
Gmail limits attachments to 25MB, Outlook to 20MB. If you are attaching multiple uncompressed photos (5-15MB each), the total exceeds these limits. Compress with MiniPx first.
Will recipients notice the compression?
At Smart quality and 1280px width, the compression is invisible when viewing on screen. Images look identical to originals in an email context.
Can I compress multiple photos at once for email?
Yes. Add all your photos at once and compress them in batch. There are no file limits. Each compressed file is typically 100-300KB.
