What inputs does Before/After Slider accept?

Before/After Slider accepts the file types listed in the tool UI. Convert unsupported formats first or use a related Tentaco tool.

Are files uploaded?

No. Before/After Slider processes the standard mode locally in your browser; Tentaco does not receive your input for that path.

Is there a file size limit?

Practical limits depend on your device and browser memory. Very large files may be slow or fail in Before/After Slider — shrink the file and retry.

How do I download the result?

After processing, Before/After Slider shows a download action. Save locally; Tentaco does not auto-archive to a cloud library.

Does it work on mobile?

Yes, Before/After Slider runs in mobile browsers. For very large media, desktop is often more comfortable.
