Frequently asked questions

How much smaller will my image get?

That depends on the original image and chosen quality. For JPG photos at quality 80%, 60-85% smaller is often achievable without any visible difference on a screen. PNG files compress less aggressively.

What is the difference between quality levels?

High (80-100%): barely visible difference, small file reduction. Medium (50-79%): good compromise, recommended for websites and email. Low (below 50%): visible quality loss, but maximum file reduction.

Can I compress a PNG file?

Yes. PNG compression works losslessly at higher quality settings. For maximum PNG reduction without quality loss you can also use the convert tool to switch to WebP.

Will text in the image stay readable after compression?

Yes, at quality settings above 70-75% text in images remains clearly readable. Below 60%, small text may become blurrier.

Why is my photo so large when the resolution is not high?

File size depends not just on pixels, but also on the compression level when saving and EXIF metadata. A phone camera often saves at high quality to preserve maximum detail.

Is my image uploaded?

No. Everything happens in your own browser. Your image never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free, without watermark or account. The site is paid for by ads.
