How to Reduce Photo File Size for Blog Post Images
Reducing file size is a sequence, not a single click. 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 Reduce Photo File Size
First crop away anything that does not belong in the frame. Every pixel you remove is data you never have to compress.
Second, resize to about 1200 pixels wide. Third, compress at quality 70, or set a target of 150 KB. Doing it in this order gives a sharper result than compressing a huge image down to a tiny file in one step.
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.
