Free image compressor FAQs

Is this image compressor really free? +

Yes. The image compressor is free to use, requires no signup, and runs locally in your browser.

Are my images uploaded to Mida? +

No. This is a no-upload image compressor. The browser reads the file, draws it to a canvas, compresses it locally, and gives you a download link.

What format should I choose? +

For ecommerce websites, WebP is usually the best output format because it gives smaller files than JPEG or PNG while maintaining strong visual quality. Use JPEG for maximum compatibility and PNG only when you specifically need PNG output.

Will this reduce image quality? +

Yes, compression reduces file size by lowering quality or resizing oversized images. The default quality is tuned for ecommerce: visibly clean while usually much smaller than the original.

Need to A/B test the images after compression?

Mida helps ecommerce teams test images, headlines, CTAs, and product page changes without slowing down your store.
