Frequently Asked Questions

Is the compression lossy?

Yes, we use JPEG compression which is lossy. You can control the quality from 10% to 100% using the slider. Lower quality means smaller file size.

Are my images uploaded?

Absolutely not. Everything runs in your browser using the Canvas API. Your images never leave your device.

What formats are supported?

You can select any image your browser supports — JPG, PNG, WEBP, GIF, BMP. The output is always a compressed JPEG for maximum compatibility.

Why is the compressed file sometimes larger?

If you choose very high quality (90–100%), the JPEG may be bigger than a well‑optimized PNG. Try a quality between 60% and 80% for the best balance.

Is QuickCompress really free?

Yes — completely free, no signup, no watermarks, no file limits. It runs entirely in your browser.

Does it work on mobile?

Yes. QuickCompress is fully responsive and works on all modern smartphones and tablets, including iOS and Android.
