Ad Safe Zone Tester

Upload a video or image, apply platform safe zones that match the exact aspect ratio, preview inside a phone frame, tweak custom margins and overlay colours, then export a still PNG or a video with the overlay. Everything runs client side. No files leave your browser.

*Results are subject to your browser and display device. The phone frame is a visual reference. Safe guides depend on the screen used to view the content. Videos and images are scaled to fit the device so safe guides can appear tighter than expected. Download image and video availability depends on the browser. Processing happens client side only. No files are sent to a server or stored by Bear Studios.

Tip the Bear

If this tool saved you from a headache, a tip keeps the honey flowing. Your support helps me maintain this Safe Zone Tester, add new presets and polish, and keep it free for the community. It also fuels the wider Bear Studios lab where I build and test new motion tools, pipelines, and prototypes that make creative work faster and sharper.

Think of it as feeding R and D. Tips cover device testing, browser quirks, hosting, bug bashing, and a steady stream of caffeine. Every jar helps. Thank you for helping an independent maker keep shipping useful things.
