Frequently Asked Questions

Can I convert HEIC photos to JPG?

Yes, our browser tool converts HEIC or PNG files to standard JPG layouts locally.

Why Does "Unsupported File Format" Happen?

Most portals only accept specific file formats (like JPEG/JPG for photographs, and PDF for certificates). If you try to upload a PNG screenshot, a HEIC file from an iPhone, or a Word document, the validator blocks the upload.

Fast Troubleshooting Checklist:

  1. Check the file extension of your document (e.g. .png, .heic).
  2. Upload your file to our local converter to change format.
  3. Download the converted JPEG or PDF and upload.
