📦 Compressore Immagini

When to use an image compressor

This tool compresses JPG, PNG, and WEBP images directly in your browser, reducing file size without sending them to a server — useful for speeding up websites or saving storage space.

When to use it

• You need to reduce photo size to publish them on a website without slowing down page load times.
• You want to compress images before emailing them or attaching them to a form with a size limit.
• You have large photos from your smartphone or camera and want to save storage space.

When NOT to use it

• You need to compress hundreds of images in a single scheduled batch operation: for very high volumes, a command-line tool is more efficient.
• You need to preserve maximum original quality for professional printing: lossy compression (JPG/WEBP) isn't ideal when maximum fidelity is needed for print.

Alternatives

• Command-line tools (e.g. ImageMagick, Squoosh CLI) for automated batch compression on large volumes.
• Server-side image optimization plugins (e.g. on a CMS) when compression needs to happen automatically on upload.

Common mistakes

• Repeatedly compressing the same image multiple times, accumulating quality loss from repeated lossy compression.
• Choosing too aggressive a compression level for images with text or fine detail, causing visible artifacts.
• Not checking the final result before replacing the original, especially for photos intended for print.
