WordPress sites slow down when images are not optimized. Instead of relying on plugins that consume server resources, compress images BEFORE uploading. This tool does it free in your browser.
WordPress image optimization plugins (Smush, ShortPixel, Imagify) use server resources and often have free tier limits. Pre-compressing before upload is faster, free, and unlimited.

Pro Tips
- Featured images: 1200×630px, quality 80% → perfect for OG sharing too

- WordPress generates multiple sizes — compress the original, WP handles the rest
- Use WebP if your theme/plugin supports it (most modern themes do)
Frequently Asked Questions
Do I still need a WordPress compression plugin?
If you pre-compress before upload, you may not need one. Plugins are convenient for bulk optimization of existing images, but pre-compression gives you more control.
What size for WordPress featured images?
1200×630px is ideal — works as both featured image and OG social share image. At quality 80% JPEG, this is typically 80-150KB.
Does WordPress support WebP?
WordPress 5.8+ supports WebP uploads natively. Most modern themes display WebP correctly. Check your theme compatibility first.
