Why people pick this one

A sharpen filter adds halos and grain. Here the detail is rebuilt, so edges are crisp without the crunchy look, and the full-size result is the free download.

Fixes
Soft focus, fuzzy edges, mushy detail from compression and downsizing. Heavy motion blur improves but cannot be fully undone.
Two ways
AI, which rebuilds edges and texture, or Classic resize, no AI, a smooth enlargement with a light sharpen and nothing added.
Comes back as
The sharpened image at 2x or 4x, as PNG, JPG or WebP.
Compare
Drag the divider across the picture and zoom right into the pixels to see exactly what changed.
Price
Free, no watermark, no sign-up. The Pro model, with every face restored, is one credit a photo with a free account.

How to sharpen an image in three steps

  1. Drop the image in. Or paste it from the clipboard. Tick Classic resize, no AI if nothing may be invented.
  2. Press Upscale and compare. Drag the divider across an edge or some text to see it go crisp, and zoom in to check for halos: there are none.
  3. Download. PNG for the cleanest file, JPG or WebP for a smaller one. Full size, no watermark.

Sharp without the halos

  • A sharpen filter pushes contrast at every edge and brings out grain and halos. Rebuilding the detail at a larger size gives crisp edges and smooth tone instead.
  • Tick Classic resize, no AI when nothing may be added: you get a smooth enlargement with a light, halo-free sharpen.
  • The Pro model, signed in, rebuilds finer texture still, with every face restored.

Questions people ask

How do I sharpen a blurry image?

Drop it here and press Upscale. Instead of a filter, the tool rebuilds edges and texture, which turns soft focus and compression blur into real detail without halos. Drag the divider to compare, then download.

Can I sharpen without AI?

Yes. Tick Classic resize, no AI and you get a smooth enlargement with a light sharpen and nothing invented, the right choice for diagrams, logos and anything that has to stay exactly as it was.

Why is the result bigger than the original?

Sharpening here works by rebuilding the picture at a larger size, which is where the clean edges come from. Keep it at 2x, or resize it back down afterwards with the resize tool if you need the original dimensions.

Is it really free, with no watermark?

Yes. The full-size result is the free download. There is no watermark, no preview-only file and no sign-up to get it.

What does the Pro model add?

The Pro model rebuilds finer detail: skin, hair, fabric and text come back with real texture, and every face is restored so eyes, lips and hairlines are clear. It is one credit a photo with a free account, and the result comes back the same way, ready to compare and download.

Which formats can I use?

JPG, PNG, WebP and iPhone HEIC go in. You can download as PNG, JPG or WebP.

Does it work on a phone?

Yes. Drop in a photo from your camera roll, pinch to zoom in on the result, and the download lands in your photos like any other file.

Why does the first photo take a moment?

The first time on a device the tool gets itself ready, which takes a few seconds. After that, photos start at once.
