Tips for the cleanest result

Use a light setting — too much smoothing blurs UI text and small icons

Save or export as PNG afterwards so you do not re-introduce JPEG artifacts

Denoise before any resize so the smoothing matches the final pixels

For text-heavy captures, denoise gently, then add a light sharpen pass

Frequently Asked Questions

Can the denoiser remove JPEG compression artifacts?
It smooths the fine speckle and softens the blocky look that heavy JPEG compression creates. It cannot rebuild detail the compression discarded, but flat areas and gradients look noticeably cleaner.
Will denoising blur the text in my screenshot?
A heavy setting can soften small text, since the filter averages nearby pixels. Use a light amount on text-heavy captures, and follow up with a gentle sharpen pass if the letters need crisping.
Is denoising images free?
Yes — it is free, unlimited, and watermark-free, and it runs entirely in your browser so nothing is uploaded. The full-resolution image downloads instantly.
