Increase image resolution Turn a low-resolution image into a high-resolution one, 2x or 4x, without the blur.

How to increase the resolution of an image
- Drop the image in and pick 2x or 4x. The page shows the exact result size before you start: a 1200 by 800 image at 4x is 4800 by 3200.
- Press Upscale and compare. Drag the divider to see the rebuilt detail against the original, and zoom in to check.
- Download. PNG for the cleanest file, JPG or WebP for a smaller one. Full resolution, no watermark.
Where a higher resolution is required
- Printers want 300 dpi. A 1200-pixel image at 4x is 4800 pixels, a sharp 16-inch print.
- Marketplace listings
- Amazon and Etsy ask for 1000 pixels or more on the long side, and zoom needs 2000. A small supplier image gets there.
- Website images
- Hero images and banners at full width without the soft look on a big screen.
- Presentations and video
- Images that stay crisp on a 4K screen or in a 1080p edit.
- Profile and cover photos
- Platforms downscale, so start bigger than they ask.
Resolution that carries real detail
- A bigger pixel count only helps when the pixels carry detail. The tool rebuilds edges and texture at the new size instead of copying pixels, so the result looks like a photo taken at that resolution.
- Tick Classic resize, no AI for a plain enlargement with a light sharpen when nothing may be added, as for a diagram or a logo.
- The Pro model, signed in, rebuilds finer texture still, with every face restored.
Questions people ask
How do I make an image high resolution?
Drop it here, pick 4x and press Upscale. The tool rebuilds edges and texture at the larger size, so the result is a genuinely higher-resolution image, not a stretched one. Drag the divider to compare, then download.
What do 2x and 4x mean?
2x doubles the width and height, so a 1000 by 800 photo becomes 2000 by 1600 with four times the pixels. 4x makes it 4000 by 3200. Pick 2x to clean up a photo that is already a decent size, 4x to make a small one big enough for print or a full screen.
What resolution do I need to print?
Divide the pixel count by 300 for inches at print quality: 3600 pixels is a 12-inch print. Pick the scale that gets you there; the page shows the result size before you start.
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 is the biggest image I can upscale?
Results go up to about 8K on the long side. A very large photo is worked on at a smaller size first so the result fits in the browser, and the page tells you the exact size before you press the button.
Can I enlarge without AI, so nothing is invented?
Yes. Tick Classic resize, no AI and you get a smooth enlargement with a light sharpen and nothing made up, the right choice for a diagram, a logo or anything that has to stay exactly as it was.
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.
