How to Compress Images for Email Without Losing Quality
If you have ever tried to send photos by email and received an “attachment too large” message, you are not alone. Modern phone photos can be several megabytes each, and sending multiple images through Gmail, Outlook, or Yahoo Mail can quickly become difficult.
The easiest solution is to compress images for email before attaching them. This reduces file size, makes emails send faster, and helps recipients download images more easily without losing noticeable quality.

- High-resolution phone photos
- Multiple images attached to one email
- Uncompressed PNG files
- Large screenshots
- Resume or portfolio images exported at full quality
Gmail and Outlook Attachment Size Limits
Gmail allows attachments up to 25MB. Outlook attachment limits may vary depending on account type, but large files can still cause sending problems, slow uploads, or delivery issues. Even when a file is technically allowed, smaller images are usually better for email.

|---|---|
| Gmail attachments | Under 10MB |
| Outlook attachments | Under 20MB |
| Resume or job application emails | Under 2MB |
| Business emails | Under 5MB |
