Frequently Asked Questions

Is Image Compressor free?

Yes, PivaBox Image Compressor is completely free to use. There are no charges, subscriptions, or hidden fees. All processing runs locally in your browser.

Are my images uploaded to a server?

No. All image compression and resizing happen entirely in your browser using the Canvas API. Your images never leave your device, ensuring your files stay private and secure.

How much can I reduce file size?

File size reduction depends on the image content and quality setting. For photographs, a quality setting of 60-80% typically achieves 50-80% size reduction with minimal visible quality loss. For screenshots and graphics, using WebP format can often achieve even better compression than JPEG at the same quality level.
