For images, files up to 50 MB work well. For videos, keep files under 500 MB for best in-browser performance — larger files require more memory to process frame-by-frame. If your video is long or high-resolution, consider trimming it before uploading.

Video processing happens entirely in your browser — no files are ever sent to a server. This keeps your content 100% private, but encoding speed depends on your device. A 15-second 1080p clip typically takes 1–2 minutes on desktop. Shorter clips and lower resolutions encode much faster.

The QR code is placed in the top-left corner. Make sure faces, logos, and important text are centered or in the right side of your frame. A plain or blurred background in the top-left corner makes the QR code easier to scan.

Keep it short and action-driven. Great examples: "Scan to shop", "Tap to get the deal", "Scan for the link". Avoid vague CTAs — tell viewers exactly what they'll get when they scan. Shorter CTAs display better on smaller screens.

Link directly to the most relevant destination — a product page, landing page, or offer. Avoid linking to your homepage if the content is about something specific. We also recommend using a link tracker (like Bitly) so you can measure how many people scanned your code.

No. All processing happens locally in your browser. Your images and videos never leave your device — nothing is sent to ROO$TER servers. Your content stays completely private.
