How to use

Upload your image — drag and drop it onto the page, or click to select a file from your device.
Adjust the settings until the preview looks right for your needs.
Download the result — your file is processed locally and never leaves your device.

Do I need to register or install software?

No. All processing happens locally in your browser. No registration, no installation required.

Will my images be uploaded to a server?

Never. Everything runs on your device: images are read and rendered by the browser, never uploaded to any server. Your privacy is safe.

Any size or duration limits for GIF?

GIFs are assembled locally. Keep frame count and dimensions reasonable for better performance and file size.

What format are extracted frames?

Each frame outputs as PNG with transparency support. Download individually or as zip.
