How to Sharpen a Blurry Photo on iPhone
Cleanr by MRVL includes a dedicated photo unblur and sharpen tool that restores clarity to blurry iPhone shots in one tap. The free tier gives you 3 daily enhancements, no watermark, and no signup required.
The quickest way to sharpen a blurry photo
Open Cleanr, select your blurry photo, and tap the Sharpen tool. The app uses advanced sharpening algorithms to enhance edge definition and reduce blur without introducing noise or artefacts. The preview updates in real time as you adjust the intensity slider. When you're happy with the result, export at full quality with no watermark. The whole process takes under 30 seconds on most iPhone models.
When unblur works best
Cleanr's sharpen feature works well on photos with slight motion blur, out-of-focus backgrounds, or general softness from low light. If your photo is severely blurry from camera shake or extreme close-up focus, the results will be limited. Sharpening cannot recover detail that was never captured. However, combining the sharpen tool with Cleanr's night denoise feature often helps recover detail in dim-light shots where blur and noise occur together.
Combine sharpening with other cleanup tools
Sharpening works even better when paired with other enhancements. Run auto-enhance first to optimise exposure and colour, then apply sharpen, and finish with adjustments like brightness or contrast if needed. Cleanr's batch process (available in Plus tier) lets you sharpen 10 photos at once with the same settings, saving time if you have a series of similar shots.
Free vs paid sharpening limits
The free tier includes 3 sharpen operations per day, which covers most casual users. If you need unlimited sharpening or want to process photos in batches, the Plus plan (£3.99 per month or £29.99 per year) unlocks unlimited enhancements and batch processing of up to 10 photos. The Pro tier adds commercial licensing, while AI Pro includes advanced selective adjustments so you can sharpen only specific areas of a photo using a brush mask.
Why Cleanr instead of other sharpening apps
Most photo apps force you to choose between a watermark on free exports or a subscription with dark patterns and credit systems. Cleanr offers high-quality sharpening with no watermark, no ads, and no signup wall on the free tier. You also get 22 other tools in one app, so you don't need to juggle separate downloads for object removal, background fixes, or restoration. The sharpness adjustment slider is also available in the main adjustments panel for fine-tuning during post-processing.

Frequently asked questions
Can Cleanr fix a very blurry photo?
Cleanr can sharpen photos with moderate blur, but extreme motion blur or severe out-of-focus shots have physical limits. The app can enhance edge definition and reduce softness, but it cannot invent details that were never captured by the camera sensor.
Is there a watermark when I export sharpened photos?
No. Cleanr's free tier exports with zero watermark, unlike many competitors. You keep full ownership of your edited photos from day one.
How many photos can I sharpen per day on free?
You get 3 sharpen operations daily on the free tier. Plus (£3.99/mo) gives unlimited sharpening and batch processing for 10 photos at once.
Can I sharpen only part of a photo?
On the free and Plus tiers, sharpening applies to the whole photo. The AI Pro tier (£12.99/mo) adds selective adjust with a brush mask, letting you sharpen specific areas like faces or text while leaving the rest unchanged.
What's the difference between sharpen and auto-enhance?
Auto-enhance in one tap optimises colour, exposure, and overall clarity across the photo. The sharpen tool specifically targets edge definition and blur reduction. Use auto-enhance first, then sharpen if you need more edge crispness.
Does Cleanr work on Android?
Cleanr is available on iOS. The full feature set, including the sharpen tool, works on any recent iPhone model running iOS 15 or later.
