Why these guides exist
People often search for a situation rather than a tool name: “make a photo under 300KB,” “my iPhone photo will not upload,” or “merge PDFs on my phone.” These guides connect that problem directly to a tool that can solve it.
We only add guides for tasks that TOOLKIT can actually perform. If a workflow is missing, tell us on the contact page.
