Images under 1MB are compressed

On the FAQ page, it says "if the image is over 1MB then it will automatically be compressed or resized to 1MB", however I constantly have PNG images that are under 1MB compressed into JPEG. Please either update the FAQ with the proper size limit, or fix the algorithm that detects the size so that it doesn't compress images under 1MB. I did some quick testing, and it seems anything over approximately 770KB will be compressed.
