How resizing works
Give one side and FITFILE keeps the shape; give both to fit inside a box, or switch off proportions for an exact stretch. Downscaling uses the browser's high-quality resampler, so a 4000-pixel photo becomes a clean 1920-pixel one — usually far smaller on disk too. The result opens in the FITFILE Workbench, where you can also compress it under a size limit or enlarge it without re-uploading.
