Hey hunters 👋 I'm Antoine, the maker.
Like most of you, I keep getting asked to send a photo of my passport or ID — for a rental, a bank, an Airbnb, a KYC check. Every time, the same thought: where does this scan end up, and what stops someone from reusing it? Identity theft is a real, expensive problem, and watermarking your ID with its intended use (e.g. "For HSBC account opening – 12 June") is the simplest deterrent.
The catch: almost every "watermark your ID" tool — including the official French government one — uploads your file to a server first. That always felt wrong for a privacy tool.
So I built Kavrylo. It does the whole thing in your browser: your document is never sent anywhere, never stored, never seen by us. You add the text and layout, and every mark also carries a small "Secured by Kavrylo" line. Works on photos and multi-page PDFs, exports as PNG or PDF. No account, no limits, free.
I'd love your honest feedback — especially on the watermark legibility and which use cases you'd want next. What document do you get asked to send most often?
