How to Compress Images for eBay Listings on Mac
Mac users can compress JPEGs without opening Preview or Photoshop. Listings with clear, fast-loading photos make it easier for buyers to compare items quickly.
Recommended settings for eBay listings
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 300 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 1600 pixels and a quality near 78.
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 eBay listings.
Step by step with TheCompressJPEG
- Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.
- Drop in your image. Nothing is uploaded; it is processed in your browser.
- Set the maximum width to 1600 and the target size to 300 KB.
- Press Compress, check the result and download it.
Quick tips
- Write a size limit slightly below the stated maximum to leave a margin.
- Process private images locally rather than uploading them to unknown servers.
- Crop out distractions so pixels go to the subject.
- Use WebP where it is supported and you control the page.
