Compress an Image for Email
Shrink image file size so it fits within email attachment limits. We reduce the file size by compressing JPEG quality and resizing oversized images — the result is visually similar to the original but significantly smaller.

Frequently asked questions
- Results vary by image. A 5 MB phone photo typically compresses to under 500 KB at balanced quality while remaining clearly viewable.
- Very wide images (over 1600 px) are resized as part of compression. Otherwise pixel dimensions are preserved.
- JPEG is almost always better for photos sent via email. PNG is larger and better suited for graphics with transparency or sharp lines.
