WordPress makes publishing easy, but it doesn’t optimize your images for you. Uncompressed photos balloon your media library, slow your pages, and drag down Core Web Vitals. Compressing before upload is the cleanest fix.
How to optimize images for WordPress
- Upload your image to this tool.
- Choose Balanced for content images, Maximum for decorative ones.
- Download and upload the compressed file through your WordPress Media Library.
Why pre-compression wins
- Zero plugin overhead — no background jobs, no CPU load on shared hosts.
- Storage savings — a 2MB photo becomes ~200KB in your library.
- Faster site, better SEO — image weight is the biggest lever on load time.
Privacy, always
Your images are compressed locally in the browser and never uploaded — even your unpublished content stays confidential.
Frequently Asked Questions
Why should I compress before uploading to WordPress?
WordPress keeps original files at full size. Server plugins compress on-the-fly, but pre-compressing saves storage, CPU and keeps thumbnails fast from day one.
What's a good target size for WordPress images?
50–300KB per image is typical for content. Featured images can go up to 500KB; keep them reasonable to protect LCP scores.
Does compression affect image quality on my site?
Balanced mode preserves on-screen quality. You can verify with the savings preview before uploading.
