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.
Open a .step / .stp part and it measures itself: volume, thinnest wall, draft and undercuts on load, and a hole list with a BOM in one click. Measure, section, export STL.

Cheese from France, Jura massif
Raw cow milk is warmed to no more than 34 °C and set with rennet, and the curd is shaped into two blocks with a thin layer of vegetable charcoal smeared between them before pressing. The salted wheel ripens on spruce boards at 7–15 °C for at least 45 days while its rind is rubbed with water and ferments. Made in 6 steps over 45 days. The longest step, ripen on spruce boards, rubbing the rind, takes at least 45 days (Cahier des charges de l'appellation d'origine…) and runs at 7–15 °C (Cahier des charges de l'appellation d'origine…). Selected lactic cultures does most of the fermenting.

Morbier's black line is vegetable charcoal smeared by hand between two blocks of curd before pressing, where other pressed cheeses have a plain paste. The milk is raw, the vat never goes above 45 °C, and the wheel ripens at least 45 days on spruce boards with a rubbed rind.
The milk is raw.
Hazards the sources name: Salmonella enterica serovar Dublin, isolated from Morbier cheese.
Every number is labelled with how it is known. How this atlas is made
The specification says farms once made Morbier from two successive milkings; the first curd was coated with soot from under the kettle to protect it until the second was added, which left the line.
