What browser upscaling can do

Upscaling increases pixel dimensions and smooths the enlarged result. Sharpening can improve edge definition, but enlargement cannot recreate fine detail missing from the original. This tool uses deterministic browser resampling rather than generative enhancement.

常見問題

Does upscaling create new detail?

No. It interpolates existing pixels and can sharpen edges, but it cannot recover detail absent from the source.

Why is there a pixel limit?

Very large canvases can exhaust browser memory, so the tool blocks unsafe output sizes.

我的圖片上傳了嗎?

No. The enlargement runs in your browser.
