—About Sharpen Image
The Sharpen Image tool increases edge contrast with an adjustable amount and live preview, plus undo, redo, and reset. It helps recover crispness in slightly soft photos.
A touch of sharpening can rescue a slightly soft image. Doing it locally lets you judge the effect live and keeps the photo private.
Step by step
- Drop the soft image you want to sharpen into the tool.
- Increase the sharpen amount gradually while watching the preview.
- Use undo and redo to compare, or reset to the original.
- Download the sharpened image.

Tips for best results
- Sharpen sparingly; too much creates halos and amplifies noise.
- Sharpening cannot fix motion blur or focus that was badly missed.
- Apply sharpening last, after resizing to the final dimensions.
