Increase Photo Resolution

Choose the photo above, pick 2x, 4x, HD or 4K, click Upscale and download the result. An AI model enlarges it on your device and sharpens edges, removes noise and smooths out compression blocks as it goes. To increase photo resolution in a desktop editor instead, you resize with resampling, which adds pixels but no new detail.

Both, in a sense. The pixel count really goes up, and the model fills in sharper edges and texture that look plausible. That detail is the model's best guess, not detail the camera captured and lost, so no upscaler can promise zero quality loss. Check the result against the original with the slider before you use it.

Use this page. It is free, needs no account or install, adds no watermark and has no daily limit; the work happens in your browser. The AI model and the software that runs it are open source.

Pick the smallest output whose pixel size meets where the photo is going. 2x and 4x multiply the width and height; HD sets the long edge to 1920 px and 4K to 3840 px. A 382 x 512 photo comes out at 764 x 1024 at 2x and 2865 x 3840 at 4K.

Printing needs pixels. Divide the pixel width by the pixels per inch your printer asks for to get the print width in inches: a 3840 px edge at 300 is 12.8 inches. Ask the printer for the pixel size it needs and pick the output that reaches it. If the shop also wants a DPI value written into the file, our DPI converter page does that.

No. Your image is upscaled on your own device and is never uploaded to our servers. The model runs in your browser, and the result exists only on your screen until you download it.

Usually a few seconds on a normal laptop. On our test Mac in Chrome a 382 x 512 photo took about 4 seconds at 2x, 6 seconds at 4x and 8 seconds to 4K. The first visit also downloads the model.

It helps with mild blur, noise, pixelation and JPEG blocks. It is not a photo restoration tool: it won't remove scratches, add color or rebuild a face. Very small, heavily blurred text may come out reshaped, so check it.

No, one photo at a time. When a result is downloaded, choose the next photo and upscale again; there is no queue and no count.

You can increase photo resolution in a mobile browser too. Results over about 16.7 megapixels on iPhone and iPad, or about 50 megapixels on a computer, are refused with a message, so 4K works on both. Export HEIC photos as JPG first.
