Image Upscaler
Enlarge images to 2x, 3x or 4x resolution with high-quality browser resampling.

Choose a controlled enlargement, confirm exact output pixels and compare the rendered result before export.
Upscaling creates more pixels with high-quality interpolation. It improves compatibility and print size, but cannot recover details that were absent from the source. Unsafe scales above 8192px per side or 64 megapixels are disabled to protect browser memory.
Important: Interpolation creates additional pixels but cannot recover facial detail, text or texture that is absent from the original.
About the Image Upscaler
Image Upscaler increases an image's pixel dimensions with the browser's highest-quality interpolation mode.
It is useful when a website, print layout or presentation needs specific dimensions, while honestly avoiding claims that missing source detail can be reconstructed.
Processing stays in the browser, and explicit 8192px-side and 64-megapixel safeguards prevent enlargement settings that would create unsafe canvas memory demands.
Key features
- 2x, 3x and 4x enlargement
- High-quality smoothing
- Exact dimensions and megapixel summary
- 64MP and 8192px browser-memory safeguards
- PNG, JPG and WebP exports
How to use
- 1Upload a PNG, JPG or WebP image.
- 2Choose an available enlargement factor while checking dimensions and megapixels.
- 3If a scale is disabled, resize the source smaller instead of forcing an unsafe browser canvas.
- 4Review the interpolated result, choose a format and download.

Frequently asked questions
- Does upscaling create new detail?
- No. It creates interpolated pixels for smoother enlargement but cannot recover missing facial detail, text or texture.
- Which format keeps transparency?
- Choose PNG or WebP. JPG fills transparent areas with white.
- Why can 4x be slow?
- A 4x enlargement contains sixteen times as many pixels as the source and can use substantial browser memory.
- Is the image uploaded?
- No. Resampling runs on a local Canvas.
