How enlarging works
Smooth interpolation
Enlarging increases the pixel dimensions of your image and fills the new pixels using high-quality interpolation, so edges stay smooth instead of jagged. This is ideal when you need a bigger version of a logo, icon, or photo for print or a high-resolution display.
Interpolation can't invent detail that wasn't captured, so very low-resolution images will look softer when enlarged a lot. For best results, start from the highest-quality source you have and use 2× before 4×.
When to enlarge
Common cases: meeting a platform's minimum dimension requirement, printing a small image larger, or upscaling an icon for a high-DPI screen. For shrinking instead, use the resizer.
Private and free
The upscale is computed on a canvas in your browser, so there's no upload, no queue, and no watermark — download the enlarged image instantly.
Frequently asked questions
Does this add detail like AI upscalers?
No — it uses high-quality interpolation to scale smoothly. It won't hallucinate new detail, but it avoids the blocky look of naive scaling.
How much can I enlarge?
Choose 2× or 4×. Smaller multipliers keep the result sharper.
What format is the output?
A high-quality image you can download and use anywhere.
Is my image uploaded?
No. The upscale happens locally in your browser; nothing is sent to a server.
