Enhance before sharpening
Start with PhotoBoost restoration to improve the source, then apply adjustable sharpening to the enhanced result instead of exaggerating noise in the original.

Image Sharpener FAQs
What is the difference between sharpening and upscaling?
Sharpening increases local clarity and edge contrast. Upscaling increases pixel dimensions. For a small, soft image, using enhancement and upscaling before final sharpening often produces the most useful result.
Can PhotoBoost fix every blurry photo?
No tool can recover detail that was never captured. PhotoBoost works best on mild or moderate softness, compression and low resolution; severe motion blur or fully missed focus may remain limited.
Will sharpening create halos or noise?
Excessive sharpening can exaggerate edges and noise. PhotoBoost provides an adjustable amount so you can stop when the image looks clear without appearing harsh.
Can I sharpen a photo on my phone?
Yes. PhotoBoost is available in the browser and through its iPhone and Android apps.
