Platform Presets
Image canvases for social networks, streaming, app stores and everyday design jobs. Each page distinguishes a source-backed size from a FitShift export option.
Why exact dimensions matter
What happens if I upload the wrong size?
Platforms may crop or compress images when their shape differs from the display area. Starting from a recommended export size gives you a predictable canvas, but each platform can still crop it differently by device and placement.
Does FitShift upload my images?
FitShift's image code does not upload the selected file. The browser processes it locally. Loading the website still sends ordinary requests to the hosting provider.
Is there a limit on file size or number of images?
Each input is limited to 50 MiB (52,428,800 bytes) and 100 million pixels. A device can run out of memory below those limits. The tool handles one image at a time and does not impose a daily conversion quota.
