Is the image enlarger an AI upscaler?

It is resampling on a canvas, separate from an AI model that invents new texture. Enlarging walks in steps of up to 2× with high smoothing, then an optional sharpen. A small, soft photo becomes a larger version of that same photo. Detail that was never in the file stays absent. The work runs in your browser, and the picture is not uploaded.

What presets and pixel limits does the image enlarger offer?

The presets are 2×, 4×, and 8×. You can also type a width and height. Each side is kept between 1 and 10,000 pixels. Growing uses progressive 2× canvas steps with high smoothing. A size smaller than the original is a single draw, and the download stays off until the result is larger than the picture you added.

Why is the enlarger download unavailable after I pick a size?

The download stays off until the result is larger than the original. A matching size, or a shrink, is not an upscale on this page, so the button waits. Type a width and height above the current pixels, or use 2×, 4×, or 8×. Each side still has to stay within 1 to 10,000 pixels.

What do sharpen, contrast, and brightness do on the enlarger?

Sharpen starts at 25 and uses a 3 by 3 kernel blended over the scaled picture. Set it to 0 if you want the resample alone. Contrast and brightness start at 0 and run from -100 to 100. They adjust the canvas after the scale. They still work with the pixels you already have, rather than painting in detail from somewhere else.

Which image formats can I enlarge, and what do I download?

JPG, PNG, and WebP. JPEG and WebP downloads use quality 0.92. A PNG stays a PNG. The file is larger in pixels once the download is available, and it may be larger in bytes too. The picture is resampled in the browser. Other formats need to become one of these three before this page can scale them.

Does enlarging a photo happen in the browser?

Yes. The preview, the 2× smoothing steps, the sharpen, and the download run on your device. The image is not uploaded. That is why a very large 8× result depends on the computer you are using. Stay inside 10,000 pixels on a side, and keep the original if you might want a different multiple later.

Is increasing image resolution a different tool?

It is this same enlarger. Presets are 2×, 4×, and 8×, or you type a width and height. Each side stays between 1 and 10,000 pixels. The work is resampling on a canvas, with sharpen starting at 25, not an AI model that invents texture. JPG, PNG, and WebP open here. JPEG and WebP save at quality 0.92, and PNG stays PNG. The download stays off until the result is larger than the picture you added.

Image Enlarger: a larger JPG, PNG, or WebP

Scale a JPG, PNG, or WebP with 2x, 4x, or 8x, or type a size up to 10,000 pixels. The preview is drawn in this browser.

The image enlarger makes a JPG, PNG, or WebP larger in your browser. Pick 2×, 4×, or 8×, or type a width and height, and download a file with more pixels than the one you added. Each side stays between 1 and 10,000 pixels. When the target is larger than the original, the canvas grows in steps of up to 2× with high-quality smoothing, instead of one jump to the final size. A smaller target is a single draw. The download stays off until the result is larger than the original, so this page is for enlarging. Sharpen starts at 25 and uses a 3 by 3 kernel. Contrast and brightness start at 0 and run from -100 to 100. JPEG and WebP downloads use quality 0.92. A PNG download stays a PNG. This is resampling. It enlarges the pixels you already have rather than inventing detail that was never in the photo. A small, soft source becomes a larger, soft image, and sharpen can crisp the edges a little without painting in a face that the file never contained. An AI upscaler that generates new texture is a different kind of tool. The work stays on your device. The picture is not uploaded. JPG, PNG, and WebP are the files this page opens.

Larger pixels from the photo you have

Use a preset when you want a simple multiple, or type the width and height a form listed. Each side stays between 1 and 10,000 pixels, and the download waits for a real upscale.

How it works

1
Add a JPG, PNG, or WebP
The preview reads the original width and height. That size is what the upscale is measured against, and the download stays off until the new result is larger. The picture stays in the browser. JPG, PNG, and WebP are the formats this page opens.
2
Pick 2×, 4×, 8×, or type pixels
Presets are 2×, 4×, and 8×. A typed width and height is clamped between 1 and 10,000 pixels on each side. Enlarging uses progressive 2× canvas steps with high smoothing. A shrink is one draw. Sharpen starts at 25 on a 3 by 3 kernel if you leave it alone.
3
Download the larger image
The button is available once the new size is larger than the original. JPEG and WebP use quality 0.92. PNG stays PNG. Contrast and brightness start at 0. The result is resampled pixels, so check the preview before you send it to a form that asked for a bigger file.

Use cases

A form that asks for more pixels

Type the width and height it listed, as long as each side is between 1 and 10,000. The download stays off until that size is larger than the original. Check the preview, because resampling enlarges the pixels you have.

A photo that should fill a larger slot

2× or 4× is the straightforward preset, drawn in 2× steps with high smoothing. 8× only helps if the source was already fairly sharp. Sharpen starts at 25 if you want a little edge crispness on top of the scale.

A PNG that should stay a PNG

PNG output stays PNG. The edges are resampled, and the file can grow in bytes as well as pixels. A vector original is still the better master if you have one, because this page enlarges the raster you gave it.

A larger image you can download

The download button is off

The new width and height have to be larger than the original. Matching the current size, or typing a shrink, leaves the download off, because this page is for an upscale. A shrink itself is drawn in one step if you are only previewing.

The larger photo looks soft

Resampling enlarges pixels rather than inventing detail. A small, soft source becomes a larger, soft image. Lower the multiple, start from a sharper original, or ease the sharpen slider, which starts at 25 on a 3 by 3 kernel.

Image tool ecosystem

After you use the image enlarger, crop framing, compress exports, remove backgrounds, or convert HEIC before upscaling.

In the browser, with the picture you brought

The canvas scale and the download happen on your device. The image is not uploaded for this tool. JPG, PNG, and WebP are the formats it opens, and the result is resampling, separate from an AI generator.

Numbers you can check on the sliders

Presets of 2×, 4×, and 8×. A cap of 10,000 pixels and a floor of 1. Sharpen starts at 25. Contrast and brightness start at 0 and run from -100 to 100. JPEG and WebP quality is 0.92. PNG stays PNG.
