Batch Compressing Photos for Blog Post Images

Updated June 2, 2026 · 8 min read

When you have dozens of images, consistency matters as much as size. Articles often carry several images, and each extra megabyte delays the moment a reader can start scrolling.

Recommended settings for blog post images

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1200 px on the long edge
Quality70
File size150 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Batch Compressing Photos

Drop all the files at once. The same settings are applied to each, so a set of photos for blog post images ends up with matching dimensions and similar file sizes.

Use Download all to collect everything in one ZIP. A target of 150 KB per image keeps the whole batch predictable.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 150 KB tool, or the main compressor for custom settings.
  2. Drop in your image. Nothing is uploaded; it is processed in your browser.
  3. Set the maximum width to 1200 and the target size to 150 KB.
  4. 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.
