Needing to make an image bigger is a common task — whether you're preparing a photo for print, enlarging a logo for a large format banner, or simply need a higher-resolution version of an image you received at a small size. With a browser-based tool, you can increase an image's dimensions in seconds without any software download.
Two Ways to Make an Image Bigger
There are two fundamentally different approaches to enlarging an image. Upscaling (increasing pixel dimensions) creates new pixels using interpolation — this is what most "make image bigger" tools do. Resampling or resizing with crop physically increases the canvas size and fills with colour, which is used for adding borders or canvas space. For most use cases, upscaling is what you need.
| Method | Use Case |
|---|---|
| Upscale (increase pixels) | Print, web display, enlargement |
| Add canvas / border | Social media frames, padding |
| Change print DPI | Change print size without adding pixels |

- Upload your image.
- Enter the target width and height in pixels — or specify a percentage scale (e.g. 200% for double size).
- Click Enlarge and preview the result.
- Download the enlarged image.
Realistic Expectations for Enlargement
Small Images Can Only Be Enlarged So Much
If you start with a 100×100px image and enlarge it to 1000×1000px, the result will look blurry regardless of the algorithm — there simply isn't enough original data to create sharp detail at 10× scale. For best results, keep enlargements to 2–4× the original size for photos, and slightly more for simple graphics with clean edges.
Graphics Enlarge Better Than Photos
Logos, icons, and text-heavy graphics generally enlarge better than photographs. Their clean, defined edges make it easier for upscaling algorithms to reproduce them accurately. If you have the source file in SVG format, use that for truly unlimited scalability without any quality loss.
