How to compress an image for email
By Sekora Studios · Updated
Open Compress Image, choose the photo, set a target at or under your mailbox limit, then download the result and attach that file. Common limits are 25 MB for Gmail and many Outlook accounts; some lists and tickets sit at 10 MB or less. The compressor keeps the original format unless you change it, and it never exceeds the target you set.
Steps
- Check the limit shown by your mail app or the recipient’s instructions.
- Open Compress Image and choose a JPG, PNG or WebP file.
- Pick 500 KB, 1 MB, or a custom target that leaves room for the email body and other attachments.
- Compress, read the achieved size, and attach the downloaded copy. Keep the original on your device.
Leave headroom
An email also carries headers and sometimes several files. If the limit is 25 MB, a 20 MB photo can still fail. Aim well under the published cap when you send more than one image.
JPG and WebP usually reach a target by lowering quality. PNG may also shrink in pixel size. Check the preview if faces or text look too soft.
Several photos in one message
Compress each photo, or use Batch Compress for a group of ordinary JPG, PNG and WebP files. Add the downloaded files to the draft and watch the combined size.

What size should I pick for Gmail?
Gmail’s attachment limit is commonly 25 MB per message. Use 1 MB or a few MB per photo unless the recipient asked for a full-resolution file.
Does compression happen on a server?
No. Encoding runs in your browser.
