Image Compression Without Blurry Results

Reduce image size while keeping important details sharp.

A smaller image can speed up a page, but the smallest file is not always the best file. A product photo, a screenshot with tiny labels, and a decorative banner need different treatment.

Start with display size

Resize a copy to the dimensions the page actually needs before adjusting quality. Uploading a huge original for a small card wastes bytes before compression even begins.

Compare suitable formats

JPEG often suits photographs; PNG can preserve crisp edges or transparency; WebP is useful for many web images. Test the actual output rather than assuming one format wins every time.

Inspect the details

Look at text, hair, gradients, and sharp borders at normal viewing size. Keep the original, compare file size and visual quality, and check the image on both desktop and phone.

Before relying on the result, test a small example, keep an original copy when a file or value is transformed, and check the output in the application where you plan to use it. Browse the tools directory for a utility that matches your task, and use the other practical guides for related checks.
