Image Compression Workflow for WordPress Media Library

Updated September 25, 2026 · 9 min read

A repeatable workflow saves time and keeps results consistent. WordPress generates several thumbnails from every upload, so a heavy original multiplies into many heavy files on your server.

Recommended settings for WordPress media library

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1600 px on the long edge
Quality78
File size200 KB or less

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

Image Compression Workflow

Keep originals in one folder and never overwrite them. Export compressed copies to a separate folder named for the destination, such as WordPress media library.

Use the same width (1600 px) and quality (78) every time so your images look uniform. Batch the work instead of compressing files one at a time.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 200 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 1600 and the target size to 200 KB.
  4. Press Compress, check the result and download it.

  • Always keep the original file and compress a copy.
