Practical guides

Short, useful explanations that help visitors choose the right format and tool.

PDF workflow guide

PDFs are useful for sharing documents because they preserve layout across devices. Before compressing a PDF, keep an original copy. For sensitive documents, prefer browser-side processing whenever the tool supports it.

Image format guide

JPEG is usually efficient for photographs, PNG is useful when transparency or crisp graphics matter, and WebP can provide a strong balance of quality and file size for the web.

QR code guide

A QR code should point to a stable destination and remain readable at its intended print or screen size. Test the generated code before publishing or printing it.

File privacy guide

Local browser processing can reduce unnecessary uploads. Always check what a tool actually sends to a server before using it for confidential material.
