Questions
What sizes does Roblox want?
Game icons are 512 × 512. Game thumbnails are 16:9, ideally 1920 × 1080 and under 3 MB. Badges, passes and developer products are 512 × 512 and shown as a circle. Group icons show at up to 420 × 420, and decals bigger than 1024 px get scaled down when you upload them.
Are my images uploaded?
No. Everything happens in your browser, on your device. The images never reach my website or anyone else.
Which format should I pick?
PNG for icons, logos and anything see-through. JPG or WebP for photos and thumbnails: they look almost the same at quality 80 to 90 and are many times smaller. Roblox accepts PNG and JPG everywhere.
What does "Crop" do with a different shape?
It fills the whole new size and cuts off what does not fit. Drag the preview to choose which part stays. "Fit inside" keeps the whole image, "Add edges" fills the gaps with a color or transparency, and "Stretch" squeezes it.
Why do my phone photos come out the right way up?
Phones store a hidden "turn me" note in photos. I read it and turn the picture before resizing, and the location and camera data stay out of the new file.
