Increase Image Size

How to increase image size

1. Choose image – Select a PNG, JPEG, WebP, or GIF file from your device.
2. Set how to resize – Use Scale % (e.g. 200% = double the width and height) or set a Target width or Target height in pixels. When you set only width or only height, the other dimension is calculated to keep the aspect ratio.
3. Resize image – Click the button. The tool shows original and new dimensions (e.g. Original: 200×200 → New: 400×400). The output has real more pixels, so when you upload or crop on another site, the image stays larger.
4. Download – Save the resized image. All processing runs in your browser; nothing is uploaded to a server.

Some tools only change how the image is displayed or its metadata (e.g. DPI) without adding pixels. This tool resamples the image to a larger canvas, so the file you download has genuinely more width and height in pixels.

Settings and limits

• Accepted formats: PNG, JPEG, WebP, and GIF images.
• Scale: from 101% up to 400% of the original width and height, so this tool is for making images larger.
• Target width or height: up to 8192 pixels. When you set one side, the other is calculated automatically so the picture keeps its proportions.
• Output format: JPEG and WebP images are saved in their own format at high quality. PNG and GIF inputs are saved as PNG, so an animated GIF becomes a single still image.

What to expect from enlarging an image

Making an image larger adds pixels, but it cannot add real detail that was never captured. The tool fills in the new pixels by smoothing between the existing ones, so a photo enlarged to 400% will have more pixels but will look softer than one taken at that size. For the best results:

• Enlarge by modest amounts, such as 150% to 200%, rather than the maximum.
• Start from the highest-quality original you have, because compression artefacts in a small JPEG are enlarged along with the picture.
• Logos and flat graphics may look blurry at the edges when scaled up. If you have the original vector or a larger export, use that instead.

When this is useful

• A website or application form requires a minimum width or height and your image is slightly too small.
• You need a larger canvas for a banner, a thumbnail, or a social media placeholder.
• You want to enlarge a small screenshot or icon so it is easier to see.

Frequently asked questions

Is my image uploaded to a server?

No. The image is resized in your browser using your own device, and it is never sent anywhere.

Why does the enlarged image look a little soft?

New pixels are estimated from the existing ones, so fine detail cannot be created. This is true of any image enlargement.

Can I make an image smaller?

This tool is designed for enlarging, so the scale starts above 100%. Use your device's photo editor or another tool to reduce size.

I get an error with a very large size. Why?

Browsers limit how large an image can be created. The tool caps each side at 8192 pixels, and very large images can also run out of memory on some devices. Try a smaller target.
