Frequently asked questions
What is unsharp mask sharpening?
Unsharp mask subtracts a blurred copy of the image from itself to find edges, then boosts those edges to create a crisper appearance. It is the most widely used sharpening technique in photo editing.
Can sharpening fix a severely blurry photo?
Sharpening enhances existing edge detail but cannot recover information that was never captured. Mild to moderate blur improves well; severe motion blur has limited recovery.
Are my photos uploaded anywhere?
No. All processing happens locally in your browser using canvas. Your photo never leaves your device.
Does sharpening increase file size?
Slightly, because edge contrast increases, making the image less compressible. The output is always exported as lossless PNG to preserve the sharpened detail.
