Compress images for WordPress

Themes generate multiple sizes, but starting from a lean master image keeps your library smaller and backups lighter. Tune format and quality here, then upload to WordPress.

How it works

1

Upload Image

Click or drag an image into the drop zone — JPG, PNG, WebP, or BMP.

2

Compress

Hit "Compress" to reduce the file size. Adjust quality or format in settings.

3

Download

Save the compressed image instantly. Everything stays in your browser.

WordPress performance

Large originals inflate hosting usage and slow down editors. Compress hero and inline images to the dimensions your layout actually renders.

Modern formats

If your stack serves WebP or AVIF with fallbacks, exporting WebP here can outperform JPEG at the same perceived sharpness. Classic JPEG remains safest when plugins cannot convert uploads.

Frequently asked questions

Is this image compressor free?
Yes, completely free. No account, no limits, no watermarks.
Are my images uploaded to a server?
No. Everything runs locally in your browser. Your files never leave your device.
Will compression reduce the quality?
Slightly, depending on your quality setting. At 80% quality the difference is usually not visible to the naked eye.
Which format should I use?
WebP gives the best size/quality ratio for most images. Use JPEG for photos and PNG when you need transparency.
Does compressing images help with SEO?
Yes. Smaller images improve page load speed and Core Web Vitals, both of which influence Google rankings.
