Updated July 29, 2026 · Practical help for exact-size photo tasks

Plain-language help for the photo tasks that forms and upload portals ask for. Each guide covers when the task matters, the exact steps in TidyCrop, the trade-offs, and where the tool stops.

TidyCrop publishes guides based on how the tools actually work in the product and common requirements people see on forms and upload portals. We do not claim official approval from any government agency, school, employer, or platform. Always confirm the size, format, and file-size rules written on your form before you submit.
