Frequently asked questions

Does 2x double the file size?

Dimensions double; file weight usually grows more than double. Compress afterwards for the web.

When should I pick 4x instead?

Only when the original is very small and the destination demands more pixels.

Is quality lost?

There is no needless recompression — the result is built from the file you uploaded.
