How to Compress Images for Cloud Backups on Mac
Mac users can compress JPEGs without opening Preview or Photoshop. Backups of large photo libraries upload faster and take less quota when files are sensibly compressed.
Recommended settings for cloud backups
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 3000 px on the long edge |
| Quality | 85 |
| File size | 1000 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
How to Compress Images
Drag photos from Finder or the Photos app into the page. Set a maximum width of 3000 pixels and a quality near 85.
Press Compress and download. Because processing happens locally in Safari or Chrome, even large batches are fast and private, which helps when preparing images for cloud backups.
