Compress JPEG Images for Email (Free)
Most email providers refuse attachments above 25MB, and many corporate inboxes stop at 10MB. A single high-res photo often busts the limit. With our browser-based compressor you can shrink any JPEG to a few hundred KB and attach it normally — no upload, no app.

Open Compress JPEG for EmailWhy email rejects your photos
Phones produce 5-12MB JPEGs. Providers impose attachment caps to protect their mail servers. Compressing to 1MB or less is nearly always enough for viewing and sharing.
How to compress a photo for email
- Open the Compress Image tool.
- Add your JPEG.
- Choose a quality around 70%.
- Check the new size — under 5MB is ideal for email.
- Download and attach.
To stay well inside corporate limits, aim for under 2MB. Photographs at 2MB still open smoothly on any phone.
Private by design
Sensitive photos (identity documents, medical forms, client work) should never pass through a random server. Our compressor works locally, so only you ever see the file.

Frequently Asked Questions
What is the maximum email attachment size?
Gmail allows 25MB, Outlook around 20MB, but many corporate servers cap at 10MB. Compressing to under 2MB avoids all of them.
Can I compress several photos at once?
The tool processes one image at a time. Processing multiple images is coming in the Pro plan.
Will the image quality suffer?
At 70% quality a JPEG is visually identical to the original on screen. Only very aggressive compression shows artifacts.
