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.
