FAQ
-
Can sharpening fix a very blurry photo?
Sharpening can improve slightly blurry or out-of-focus images, but it cannot fully restore severely blurry photos. The tool works best on images that are slightly soft or lacking definition, rather than those with significant motion blur or severe focus issues.
-
Does image sharpening reduce image quality?
When used appropriately, sharpening can improve perceived image quality. However, excessive sharpening can introduce artifacts, noise, and halos around edges. Always use the preview feature to find the right balance for your specific image.
-
Will sharpening increase my image file size?
Sharpening typically has minimal impact on file size. The process changes pixel values but doesn't add new data to the image. However, if you save a previously compressed JPEG at a higher quality setting after sharpening, the file size might increase.
-
