Key Requirements at a Glance
Image and Document Conversion Specifications

Why Loose Image Uploads Cause Problems
Submitting separate JPG or PNG images for official applications—such as visa forms, employment onboarding, insurance claims, or university admissions—often triggers immediate rejection.
Portals expect a single structured document rather than multiple loose picture files that can be downloaded out of order or rotated sideways.
Converting images to a unified PDF normalizes dimensions, embeds metadata, and allows clean page-by-page viewing on any screen.
Resolution Best Practice
When photographing documents with your phone, ensure bright, even lighting. Our converter preserves original 300 DPI resolution while optimizing file compression.
Converting Word (DOCX) to PDF Without Formatting Shifts
Sharing a Microsoft Word document (.docx) directly with clients or professors is risky: if they open it on a Mac, phone, or computer without your custom fonts installed, margins shift, headers break, and page counts alter.
Converting Word to PDF locks your typography, line breaks, and vector graphics into an immutable ISO-standard document that displays identically on every machine.
