Enlarge a small image before using it in a design
Choose 2× for a modest increase or 4× for a smaller source image. A local ESRGAN model estimates higher-resolution detail. Compare the original and output before downloading; AI may change small textures rather than recover the exact original detail.

Good to know
What is the maximum image size?
The output can contain up to 4,194,304 pixels, with neither edge above 4096 pixels. A larger source may fit at 2× while 4× is disabled.
Does it keep transparent backgrounds?
No. Transparent areas are placed on white before processing. The first use downloads a model for the chosen scale; the selected photo stays on your device.
Do my files get uploaded?
Your chosen files and entered text are processed in this browser. They are not uploaded to Montagea. Signing in verifies your account. AI tools download models; image-to-prompt downloads its pinned model files from Hugging Face.
Is the download free?
Yes. Sign in with your Montagea account to use these tools, copy results and download files. They cost no credits and add no watermark.
