Hey Product Hunt 👋 I'm Leon, maker of imageserver.pw.

Why I built this: with some popular screenshot tools, you could change a single character in a share URL and land on a stranger's screenshot. And all of those images sat unencrypted on their servers. That bugged me and since I've always been into cryptography, I decided to build the uploader I actually wanted to use.

How it works:

Every upload gets its own random AES-256 key. We never store it. So even if someone guesses a file URL, all they get without the key is encrypted noise.

To be transparent, there are two link types:

- Standard links (?key=) | the key isn't stored, but our server decrypts on request so embeds work in Discord etc.

- Private links (#key) | the key stays in the URL fragment, never reaches us, and decryption happens entirely in your browser.

What you get for free:

✓ ShareX preset (set up in under a minute), desktop client for Win/macOS/Linux, and an API

✓ 25 MB per file, 2 GB storage, no watermarks

✓ Expiring uploads, deletion links, folders & search

✓ Servers in Germany, no IP logging for regular access

Paid plans (3€ / 10€) add custom domains, bigger files and original quality.

Since I'm a bit of an encryption nerd, I'd especially love feedback on the crypto model! And: what would make you switch from your current uploader?
