Are my images uploaded to a server?

No. This is a pure front-end tool. All images are processed locally in your browser and never uploaded.

Do I need to create an account?

No account is required. All features are currently available for free. Pro features are coming soon.

Why is only the first image fully visible?

By default, the first image is fully visible to provide full context. The rest are in overlay mode (stack mode) by default, optimized for subtitle screenshots. However, you can manually toggle any image (except the first one) between full visible mode and overlay mode using the toggle button on each image.

How many images can I upload?

Free users: up to 6 images. Pro users: up to 16 images.

Is there a daily export limit?

Free users: up to 5 exports per day. Pro users: unlimited exports.

Will exported images lose quality?

Free users can export in medium or low quality. Pro users can export in high resolution.

Does this work on mobile devices?

Yes. The interface is responsive and works on mobile, though desktop provides the best editing experience.

Can I upload videos directly?

No. Please take screenshots from videos and upload the image files.
