Tips

• 2x is usually enough for screens and social media.
• Upscaled files are larger — check the size before sharing.
• Works best on clean photos, not on very blurry ones.
• This is smoothing-based scaling — it does not invent new detail.

This tool uses high-quality canvas scaling in the browser — it does not invent detail like an AI upscaler, but it keeps edges sharp and blur to a minimum.
