Unblur Image Online — Free AI Photo Sharpener

Yes. The unblur tool is free to use on Visiojoy — no credit card required. New accounts receive a starting free credit allowance (a signup bonus, valid for 30 days from signup) that covers the first uses at no cost. Heavier or ongoing use beyond that is covered by paid credits from a subscription plan or a credit pack. Results on the free tier carry a small watermark; once you've made any purchase (a subscription or a credit pack), downloads are watermark-free.

It works best on mildly out-of-focus photos, low-light noise, and web-compressed images where detail was softened during upload. It also helps sharpen scanned documents and older prints. Severe motion blur or completely defocused shots are much harder — the AI cannot invent information that isn't there.

JPG, PNG, and WebP files up to 10 MB. If your file is larger, downscale it in any image viewer first — the tool works fine on downscaled versions of larger images.

You can open the page and pick a file without signing in. Signing in is required when you click Unblur, so credits and the resulting image can be attributed to your account.

Yes — this is a browser-based tool that runs on desktop and mobile. Upload the blurry image, wait 10–30 seconds, drag the before/after slider, download the sharpened result. No plugins, no desktop app, no browser extension. Works on Chrome, Safari, Firefox, and Edge on any operating system.

Yes. The whole page — upload, processing, before/after comparison, and download — works in any modern mobile browser. You can pick a photo directly from your camera roll.

Not by default. Results appear in Visiojoy's public gallery, together with the photo you uploaded. Subscribers can switch off Public Visibility before sharpening to keep the result private, or turn on Copy Protection to hide the original photo. Avoid uploading photos you don't want shared unless you've changed these settings. See our privacy notice for how uploads and results are stored.

Traditional sharpen filters increase contrast at edges, which can make an already blurry photo look harsh without adding real detail. This tool uses an AI model that predicts what the missing detail probably looked like and rebuilds it, which is why it works even when a standard sharpen filter would just make noise worse.

Traditional sharpen filters just crank up edge contrast — they can't recover detail that was lost to focus miss or motion blur. Our AI model was trained to reconstruct plausible detail from the blur pattern, which is why it works on photos where a manual slider only makes things worse. If your image is only slightly soft, a non-AI sharpen filter might be enough; for anything more than mild softening, AI is the tool that gets you a real result.

Yes. After the unblur finishes, use the Continue in editor button to open the sharpened image in the AI image editor. From there you can crop, retouch, remove the background, or apply further edits.
