Your image stays on your device: processing happens locally in the browser, with no upload to our servers. For large files, processing can use significant memory. Save the output using the Download button.
This is a free interpolation-based enlargement tool, not a neural-network AI upscaler. It increases pixel dimensions but cannot recover missing details.
Download PNGHow it works
How image enlargement works: the browser creates more pixels using interpolation. This is suitable for larger display dimensions, but it does not recreate sharp textures from a low-resolution original.
