Deblur & Sharpen
Recover detail in a soft photo with unsharp masking.
What does the deblur tool do?
The freeimgtool deblur and sharpener takes a soft-looking image and brings back edge detail. Three modes are available. Unsharp uses the classic unsharp mask: subtract a blurred copy from the original to emphasize edges. It is the most natural-looking option for slight blur. Detailuses OpenCV's edge-preserving detail enhancer, which boosts mid-frequency texture without ringing. It works well on portraits and product photos. Strong applies a 3×3 sharpen kernel mixed at the chosen strength — fast and punchy, but can introduce artifacts at very high settings.
This is not an AI super-resolution model. It cannot invent detail that does not exist in the original. It is the right tool when an image looks slightly blurry, dull, or softly focused. For severe motion blur or extreme upscaling, a dedicated AI enhancer is the better choice.

Why use this deblur tool
Photo editors bury sharpening behind layers and curves. Online AI deblurrers want a signup and watermark the result. This tool gives you the slider, the mode, and the file in three clicks. Good enough for almost every web photo, social post, or product shot.
Who uses it
Online sellers fixing soft product photos before listing them. Bloggers refreshing dull stock images. Real estate agents crisping up phone snaps before upload. Designers prepping a screenshot for a portfolio. Anyone who took a photo that just looks a little flat.
Frequently asked questions
Will this fix motion blur?
Only mild motion blur. Heavy motion blur needs a deep-learning deconvolution model, which is on our roadmap for the heavier AI tools.
What strength should I use?
Start at 1.5. If the image still looks soft, raise to 2.0–2.5. Above 2.5 you risk halos around high-contrast edges.
Which mode is best for portraits?
Detail. It boosts texture without exaggerating skin pores or dark eye edges.
Which mode is best for text screenshots?
Strong at 1.0–1.5. It crisps up letter edges fastest.
Is the deblur tool free?
Yes. No signup, no premium tier. Display ads support the site.
What is the maximum upload size?
Five megabytes per photo. The tool internally caps the long edge at 2000 pixels for predictable performance on the free server.
Is my photo stored?
Uploads are kept only long enough to return a download link and are removed automatically. Privacy policy has the details.
Does it work on a phone browser?
Yes. The upload box accepts photos directly from the camera roll.
