How to Convert PNG to JPG
Learn how to convert PNG images and signatures into crisp JPG files with solid white backgrounds to prevent form upload errors.
Why PNG Files Need Conversion for Online Forms
PNG (Portable Network Graphics) is a popular image format, especially when capturing scanned documents or digital signature cutouts. However, uploading PNG files to recruitment or admission portals frequently results in errors.
There are two primary reasons why PNG files fail on application servers:
1. File Size Bloat: PNG's lossless compression keeps photograph files large (often 200KB to 800KB), making it impossible to satisfy 20KB or 50KB size limits.
2. Transparent Background Glitches: PNG files support transparent backgrounds. When an automated exam server attempts to process a transparent PNG signature, it often turns transparent areas jet black, obscuring the signature entirely.
How PNG to JPG Conversion Handles Backgrounds
JPG files do not support transparency. When you convert a PNG file to JPG using a proper converter, transparent background pixels are automatically replaced with a clean, solid white background (#FFFFFF).
This ensures that signatures, passport photos, and document scans display with sharp dark text against a crisp white background.
