A SMALL, LOCAL WORKFLOW

Three screens.
One moving image.

Choose up to three PNG screenshots. A fixed local program makes a simple GIF and keeps the original files.

Before you download

Windows + existing Python 3.12 or later, tkinter and Pillow are required. This is a source ZIP, not a ready-to-install app. The desktop interface is in Korean.

START WITH YOUR EXISTING ENVIRONMENT

A short path from files to a GIF

  1. 01

    Extract the entire ZIP

    Use a normal writable folder on your Windows PC. Keep the supplied folders together. Shared folders and linked paths are unsupported.

  2. 02

    Open the launcher

    Run Open-Screen-Tool.cmd. Read the included README first. If your Python environment lacks tkinter or Pillow, this trial will not run; it does not install them for you.

  3. 03

    Choose screens, then make the GIF

    Select PNG files, check their order and choose the blue make button. After completion, open the result. Identical inputs reuse the stored output.

WHAT WAS CHECKED

One bounded local trial

Two program-generated PNG files were selected in the native window on the developer’s Windows PC, in a separate folder. Generation completed; a repeat request reused the same saved job. The actual GIF was displayed in a local browser.

The idle progress bar and inactive button styling were corrected after observation.

Exactly what you receive

Ten source and instruction files. No bundled Python, Pillow, model, font, credentials or customer data. The archive checksum is listed in the file and privacy notes.
