True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.
LaunchEdit text in place, sign, redact, fill forms, and reorganize PDF files in your browser — all on your device. No upload, no subscription.
Drop two versions of a contract or drawing set. Moved notes read as moves, changed values light up digit by digit, and hidden text is named.
LaunchSide-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Drop a Gerber ZIP, an ODB++ .tgz or an IPC-2581 .xml and inspect every layer — compare revisions, snap-to-pad measure, run DRC and preview the board in 3D.
LaunchOpen Gerber, Excellon, ODB++ and IPC-2581 PCB files. Inspect layers, measure traces, run DRC, export to PNG / SVG / DXF.

Cheese from Champagne humide, France
Whole cow milk is soured with mesophilic starter and a little animal rennet, then left at least 12 hours to set into a lactic curd. The curd drains without pressing in tall moulds, is dry-salted on the surface and ripens at least 14 days under a white Penicillium rind. Made in 5 steps over 16 days. The longest step, ripen under a white rind, takes at least 14 days (INAO 2013) and runs at 8–14 °C (INAO 2013). Mesophilic lactic acid bacteria and Penicillium candidum (P. camemberti), the dominant white rind mould do most of the fermenting.

Chaource is a lactic-set bloomy cheese. Its curd sets slowly over at least 12 hours, mostly by acid, so the heart stays fine and chalky, unlike Camembert's rennet curd. It is also taller than most bloomy-rind cheeses.
The specification bans freezing the milk, curd or fresh cheese and bans storing fresh or ripening cheeses under modified atmosphere.
Every number is labelled with how it is known. How this atlas is made
The specification dates the cheese to farm women of the Chaourçois in the early 19th century; it was described in 1872 in Pourriau's La Laiterie and in 1883 in a guide for Aube farm wives. It has been an appellation d'origine since 1970.
