301 private, in-browser tools
Private online tools that never see your files
Most "free" tools upload your file to a server. Bluebird doesn't. Every tool runs inside your browser tab, so your photos, PDFs and code stay on your device — even in Incognito, even offline once loaded.

No uploads
Your file stays on your device — we couldn't see it if we wanted to.
No accounts
No email, no sign-up. Open a tool, use it, close the tab.

Once a page loads, you can disconnect and keep going.

Right-click, View Source. Every step is visible.
Popular private tools
- Image CompressorA 12 MB photo down to 300 KB — no fuzzy faces, no upload, no account. Drag a JPG, PNG or WebP and slide the live before/after to find the sweet spot.
- Image CropperCrop a photo to a square, a fixed ratio, or any custom box — with a live drag-to-resize handle.
- QR Code GeneratorMake a styled QR code for a link, Wi-Fi network, contact card or plain text — with your own colors and logo.
- Password GeneratorCreate strong, unique passwords with a live strength meter. Built with secure browser randomness — never sent anywhere.
- JSON FormatterPaste anything — a webhook payload, a config, a copied fetch response. We'll indent it, sort the keys, and tell you exactly where the missing comma is.
- JWT DecoderPaste a token to see header, payload and signature. The token never leaves your browser, so it's safe for prod secrets.
- Hash GeneratorGenerate SHA-1, SHA-256, SHA-384 and SHA-512 hashes from text or any file — and verify a download with one paste.

Why "browser only" actually matters
Your file never leaves your device
A screenshot of your passport, a contract PDF, a private photo — none of it is uploaded. The tool code runs where you are.No server means no breach
We can't lose what we never had. There's no "Bluebird database of your files" for an attacker to steal.Faster too
Skipping the upload/download round-trip usually makes browser tools quicker than server ones for typical file sizes.
