Turn text or a small file into a self-contained image — no account, no server, no upload. Everything runs on-device, in your browser. We never see what you encode.
How it survives being reposted
The image is a data carrier, not a photo with something hidden inside it — every module is set to maximum contrast on purpose, tuned to survive real JPEG recompression and resizing from platforms like Instagram, WhatsApp, and Twitter/X. Repost it, screenshot it, save and re-upload it — it still decodes.
