What is ToolBox Online?
ToolBox Online brings together simple tools for everyday tasks — formatting code, converting images, generating QR codes, editing PDFs — without installing any software or creating an account.
Most tools process the file or text directly in your browser: nothing is sent to a server for the operation to happen. Each tool's page states this clearly.
