About the Universal File Converter
The Universal File Converter provides instantaneous format conversions for various files. Most exam portals strictly restrict uploads to JPEG/JPG formats for photos/signatures and PDF formats for certificates, rejecting other popular file types like PNG, WEBP, or HEIC.
Our converter performs format transforms in the browser. PNG transparency is converted to a solid white background automatically, ensuring standard layout requirements are met without using offline graphics editors.

Troubleshooting & Helpful Tips
Black background on PNG conversion: Transparent PNG files sometimes render with a black background in standard converters. Our tool automatically maps transparent layers to solid white, satisfying standard requirements.
File size increases after conversion: PNG images converted to high-quality JPGs can occasionally increase in size. Slide the quality slider down to decrease the final file size.

Frequently Asked Questions
Why does the exam portal reject PNG files?
Exam portals use automated image parsers that require strict JPEG headers for parsing. PNGs are rejected to prevent file validation conflicts.
Can I convert HEIC photos from my iPhone to JPG?
Yes, upload the HEIC file, choose JPG as target format, and download the converted image immediately.
Is my uploaded file safe?
Yes. No files are uploaded to any server. All formats are parsed and converted locally in your web browser.
