Document Preparation Guides

This guide library explains common steps for preparing digital documents before uploading them to an exam, recruitment or public-service form. The instructions are general: the current official notification or portal always decides the required dimensions, file size, format and other conditions.

Photo and signature preparation

Start with a clear original image, check the background and framing, then resize or crop only to match the official instructions. Avoid excessive sharpening, filters or edits that change the person's appearance.

PDF preparation

Before merging, rotating or compressing PDF files, keep a copy of the originals. After processing, open the output and check every page, orientation, legibility and final file size.

Privacy and file safety

Identity documents can contain sensitive personal information. Use trusted devices, avoid public computers where possible, and understand whether a tool processes files locally in the browser or sends them to a server.
