Why WordPress

Heavier library.
Slower pages.

WordPress serves original uploads unless you optimize. Compress before upload — your theme and plugins do the rest.

Shrink uploads first Compress the folder, then upload. Lighter originals, deeper savings.
Export WebP Serve WebP/AVIF for 30–50% smaller delivery, keep JPG fallback.
No plugin needed Process outside WordPress — your images never leave your disk.

FAQ

WordPress — FAQ

Do I need a plugin?

No. Compress locally on Windows, then upload the small files. No plugin, no server-side processing, no upload to a third party.

Will this speed up my WordPress site?

Yes. Smaller images improve LCP and reduce page weight. Compress your media library before upload or re-upload the optimized folder.

Can I batch the whole uploads folder?

Yes. Drop wp-content/uploads — Compressy finds images in subfolders, keeps structure, writes WebP/AVIF alongside.

Do I need to upload?

No. All compression is local. No upload, no account.
