This website accepts JPEG.
So first of all, you got to understand that, for the same image size of 640x640 pixels, JPEG compression could make that same image either 50kb or 150kb.
This is called JPEG compression, or in general terms, JPEG quality.
Of course, it is common sense that a 50kb 640x640 pixel image will be of poorer quality compared to a 150kb 640x640 pixel image.
When saving your file in JPEG, adjust the Compression, or Quality, or whatever the software calls it. This will keep our photo at the same pixel size, but smaller file size (150kb for DPChallenge submission) |
