Compress Images for Email Attachments
Prepare one or many photos with an email-friendly 1,000KB limit and a maximum width of 1,600 pixels. The preset creates broadly compatible JPG files without sending the images to a server.

Private: one or many images stay on your device. The server receives no file.
How to prepare images for email
- Choose one or more photos from your device.
- Keep the 1,000KB, 1,600px and JPG preset or adjust it for your email service.
- Run the local compression and review the size shown for every result.
- Download individual JPG files or the ZIP and attach them to your message.
Make photo attachments easier to send
Large camera photos can consume an email provider's attachment allowance before the message is sent. This tool resizes oversized images, adjusts JPG quality and checks every result against the selected 1,000KB limit. Smaller originals are not enlarged merely to reach 1,600 pixels.
Email attachment preset
The starting preset uses JPG output, a 1,000KB maximum per image and a maximum width of 1,600px while preserving the original aspect ratio. You can change any value or save your own preset in this browser.
What you receive
Each selected image gets its own downloadable JPG and a clear original, result and target-size summary. For a batch, the finished files can also be downloaded together as a ZIP.
Useful for
- Sending phone photos without exceeding a mail service's attachment limit.
- Sharing several review images in one message.
- Reducing a photo before attaching it in webmail or a support form.
Email limits still vary
Email providers count the complete message, not only the visible image files, and some use a lower total allowance. If several 1,000KB images are still too large together, choose a smaller KB target. JPG does not retain transparent backgrounds.
FAQ
Are my email photos uploaded?
No image bytes are uploaded by the compressor; processing happens in this browser. Small, separate usage events may be sent without the files or their contents.
Can I compress several attachments at once?
Yes. Select multiple images, review each result and download all successful files as one ZIP.
Why does the preset use JPG?
JPG is widely accepted by email clients and usually produces compact files for photographs. Choose PNG or WebP manually when their features matter more.
