How do I compress images without WordPress?
1 min read · Last updated June 2026
Use the free compressor on the SlashImage website. Drag your images onto the page and download the smaller versions - no account, no plugin, nothing to install.
Compress in your browser
- Open the Compress tool on the SlashImage website.
- Drag and drop your images onto the page, or click to choose them.
- Download the optimized results.
Limits
Without an account, you can compress up to 10 images a day, up to 10 MB each. The count resets daily. Signing in for a free account raises the daily limit to 100; paid plans remove the daily cap.
When to use the plugin instead
The web tool is great for one-off images. To optimize a whole WordPress site automatically - new uploads and your existing library, served as WebP and AVIF - use the plugin instead. See How do I set up SlashImage?.
