Frequently asked questions

Can upscaling recover missing detail?

No. Browser resampling estimates additional pixels from existing ones. It can produce smoother dimensions but cannot reconstruct genuinely missing information.

Why is output limited to 64 megapixels?

Large Canvas images consume substantial device memory. The safeguard reduces browser crashes and failed encodes.

Should I use PNG, JPEG or WebP?

PNG is best for transparency and sharp graphics, JPEG for broad photo compatibility, and WebP for compact modern output.

Why might 4× be unavailable?

A large source multiplied by 4 in each dimension creates 16 times as many pixels and may exceed safe browser limits.
