Can sharpening fix a very blurry photo?

No. Sharpening improves images that are slightly soft or lack crisp edges. Severely blurry photos cannot be meaningfully recovered by sharpening alone.

What sharpening level should I use?

Start at 30-50% and check the preview. For portraits, 20-40% is usually enough. For product photos or text, 50-80% works better.

Will sharpening increase file size?

Slightly, yes. Sharper edges create more detail for the compressor to store, which can increase JPG file size by 5-15%.

Yes, completely free with no account or software download required.

Does my image get sent to a server?

No. All sharpening runs in your browser. Your image never leaves your device.
