How to Compress Images for Blog Post Images on Mac
Mac users can compress JPEGs without opening Preview or Photoshop. Articles often carry several images, and each extra megabyte delays the moment a reader can start scrolling.
Recommended settings for blog post images
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1200 px on the long edge |
| Quality | 70 |
| File size | 150 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 1200 pixels and a quality near 70.
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 blog post images.
Step by step with TheCompressJPEG
- Open the compress JPEG to 150 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 1200 and the target size to 150 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.

Wrapping up
