Windows Shows a Security Warning

Problem

Windows Smart App Control or Microsoft Defender warns about the application.

Why?

QIFY Downloader is currently not digitally signed.

This is common for new open-source applications from independent developers.

Solution

Download the application only from the official GitHub repository or build it yourself from the source code.

The Application Does Not Start

Check

  • Python is installed (when running from source)
  • FFmpeg is installed
  • Required Python packages are installed
  • Windows Defender has not blocked the application

Downloads Are Slow

Download speed depends on:

  • Your internet connection
  • The source website
  • Server availability

QIFY Downloader cannot increase the maximum speed provided by the source.

Audio Is Not Converted to MP3

This usually means FFmpeg is missing.

Verify:

ffmpeg -version

Install FFmpeg if necessary.

Video Has No Sound

Make sure FFmpeg is installed correctly.

Video and audio streams are merged using FFmpeg.

Cannot Build the EXE

Install PyInstaller:

pip install pyinstaller

Build using:

pyinstaller --onefile --windowed --icon=assets/qify.ico --name QIFY-Downloader main.py
