Why use this image upscaler?

AI super-resolution

A trained model reconstructs the missing pixels instead of just stretching them. The result holds up at 2× or 4× far better than a plain resize, especially on edges, text, and faces.

2× and 4× presets

Pick 2× for moderate enlargements that finish in seconds, or 4× when you need a much bigger output and can wait a bit longer.

Runs in your browser

The model loads once and runs on your device. Your photos are never uploaded to a server or seen by anyone else.

Output keeps your format

A JPG comes back as JPG, a PNG as PNG, a WebP as WebP. No surprise format changes, no extra conversion step.

Up to 5 images per batch

Queue up a small batch and let it work through them one by one. Per-image progress bars so you always know where the queue is.

Free, with no daily limit

No subscription, no two-images-a-day cap, no watermark on the result. The trade-off: it runs on your CPU, so each image takes a few seconds.

Why you might need to upscale an image

A logo that had to print on a banner

You design quietly during the week and someone in marketing pings you on Friday afternoon: the trade-show banner needs the company logo in print resolution by Monday, and the only file anybody can find is a 600 × 200 PNG someone exported for the website three years ago. The print shop wants 4× that.

You drop the PNG onto the page, pick 4×, and wait about twenty seconds while the queue runs. Out comes a 2400 × 800 PNG with crisp edges and no jagged staircases on the curved type. You send it to the printer, the banner gets approved, and your weekend stays your weekend.

The original logo file is somewhere on a hard drive someone took with them when they left. You don't need to find it.

An old family photo for the hallway frame

Your mother sends you a 900-pixel scan of your grandparents' wedding photo and asks if you can have it printed for the hallway, the size of "one of the big frames at the framing shop". The framer wants 300 DPI at A3, which is roughly 3500 × 4900 pixels. The scan is way too small.

You upload the scan, choose 4×, and let the page work for half a minute. The result isn't pixel-perfect history — no upscaler can invent detail that isn't there — but it's clean enough to enlarge to A3 without the framer wincing. The faces look the way you remember them, the edges of the wedding suit don't fall apart, and the texture of the old paper survives.

The frame goes up that weekend. Your mother takes a picture of it for the family group chat.

A 512-pixel AI artwork that needed to be a poster

You generated a piece of art on a phone-friendly AI model that caps outputs at 512 × 512, and you really like how this one came out. The print-on-demand site won't accept anything under 2000 px on the long edge.

You drop the 512 × 512 PNG onto the upscaler, pick 4×, and a few seconds later you have a 2048 × 2048 version. The textures stay coherent, the brush-stroke artifacts that AI art tends to have don't get worse, and the output's well above the print site's minimum.

You upload it. The poster ships. The original AI tool is happy not knowing it didn't win.

How it works

1

Select your images

Drop up to 5 photos on the page, or click Browse to pick them from your device. Inputs up to 4,000 px on the long edge work best.

2

Pick a scale factor

Choose 2× for fast enlargements or 4× for bigger results. The configure screen shows the projected output dimensions for each tile.

3

Wait, then download

Hit Upscale and watch the per-image queue. One image downloads directly when it's done; multiple come back as a ZIP.
