This guide explains how Media Replace works and what happens when a media file is replaced.
You’ll learn which parts of the media remain unchanged, what gets updated behind the scenes.
What stays unchanged?
When you replace a media file:
- 1. Media URL remains the same.
- 2. Attachment ID remains the same.
- 3. Existing references in posts, pages, and themes continue to work.
What gets updated?
- 1. The original image file is replaced.
- 2. WordPress thumbnails are regenerated.
- 3. Optimized formats are re-created (PNG / JPG / WebP / AVIF).
- 4. Compression settings are applied again automatically.
Designed for real-world workflows
Media Replace is especially useful for:
- 1. Updating images already used across multiple pages.
- 2. Fixing incorrect or low-quality uploads.
- 3. Replacing images while keeping CDN and cache logic intact.
- 4. Re-optimizing images with new compression strategies.
