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.

Fermented milk from Armenia
Acidophilin is a Soviet-era cultured milk soured with three starters in equal parts, the acidophilus bacterium, lactococci and a starter grown on kefir grains. The kefir yeasts give it a slightly sharp, refreshing taste and a few gas bubbles. The interstate standard GOST 31668-2012 defines it and sets its acidity. Made in 4 steps over 10 h – 12 h. The longest step, ferment, takes 10–12 h (ru.wikipedia 1956). Lactobacillus acidophilus and Lactococci do most of the fermenting.

Total time across the recorded steps: 10 h – 12 h
What changes: The milk is pasteurised, then cooled for the starters
The standard requires the heat treatment to meet the customs-union regulations but sets no temperature itself. Output: pasteurised milk.

Acidophilin uses L. acidophilus like acidophilus milk, but adds lactococci and a kefir-grain starter in equal parts. The kefir yeasts give it a slight fizz and yeasty note that plain acidophilus milk lacks.
The milk is pasteurised and the product is soured to 75–130 °T. GOST 31668-2012 requires it to be kept at 4 ± 2 °C, with the shelf life set by the maker.
Every number is labelled with how it is known. How this atlas is made
Production began in the 1930s in the Armenian SSR under Levon A. Yerzinkyan, who later developed Narine, and spread through the USSR and some socialist countries (ru.wikipedia). The current interstate standard, GOST 31668-2012, came into force in 2013 and was amended in 2016.
