Compress first. If the file is still too large, resize its longest edge to roughly 1600–2000 px. JPEG or WebP usually works well for photos; keep the original separately.
Why the photo will not send
Modern phones create detailed files that can exceed several megabytes each. Email, forms and messaging services often limit either each attachment or the total message size.
One megabyte is roughly 1,000 kilobytes. Leave some space below the stated limit instead of aiming for the exact maximum.
Reduce size in the right order
Start by adjusting compression. A quality setting around 70–85% often makes a substantial difference while preserving a good appearance.
If that is not enough, reduce the pixel dimensions. For screen viewing, a longest edge around 1600–2000 px is often sufficient. Check required resolution before resizing anything intended for print.
- Keep the untouched original
- Test one image before processing a batch
- Check the combined size of all attachments
Choose JPEG, PNG or WebP
JPEG is widely compatible for photographs. WebP can be smaller, while PNG is best for graphics or transparency and can be unnecessarily large for photos.
When a recipient specifies a format, follow that requirement. Otherwise JPEG is the safest general choice for email.
Inspect the saved result
Open the exported file and zoom in on faces, text or product details that the recipient needs to see. A descriptive filename also makes the attachment easier to understand.
Four checks before sending
- ✓Comfortably below the size limit
- ✓Important details remain readable
- ✓Correct file format
- ✓Original saved separately
Image Compressor
Compare the result and file size before downloading the compressed copy.
Image Compressor→This article gives general guidance. If a recipient, printer or official service provides its own requirements, follow those requirements first.
A SMALL NOTE FROM SPACEA photo can become lighter without making the memory any smaller. Send only the weight you need.
