Smaller email attachments without uploading
Email attachment limits can make full-resolution photos and screenshots awkward to send. A smaller JPG or WebP file is usually easier for recipients to open and download.
Start with the 1 MB target, then lower the target if your mailbox or form needs a stricter limit. The image is processed locally and downloaded from your browser.
Common uses
- Email attachments
- Client previews
- Support screenshots
- School or office documents
Compress Image for Email FAQ
What size should I use for email?
A 1 MB target is a practical starting point. Use 500 KB or less when you need a lighter attachment.
Which output format works well for email?
JPG is widely compatible for photos. WebP can be smaller, but check that the recipient can open it.
Is my attachment uploaded?
No. Compression happens in your browser before you attach the downloaded file to email.
