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 USSR
Snezhok is a soured milk drink, usually with sugar or fruit-berry syrup added. It is made from pasteurised milk soured with Bulgarian bacillus and lactic streptococci. The body is sour-cream-like and slightly viscous.
A short entry: the sources we found record only what is said here about Snezhok itself. Its own sources do not record how it is made, so the steps and scenes below are those of Ryazhenka, the closest documented fermented milk ferment, shown as a guide to the method, not as a record of Snezhok.
| pasteurised cow milk | |
| sugar or fruit-berry syrup | |
| Starter | defined-culture: Bulgarian bacillus (L. delbrueckii subsp. bulgaricus) + lactic streptococci |
Total time across the steps of Ryazhenka: 7.5 h – 12 h
What changes: The milk is homogenised and pasteurised before baking
Output: pasteurised, normalised milk.

Snezhok is a soured milk drink, usually with sugar or fruit-berry syrup added. It is made from pasteurised milk soured with Bulgarian bacillus and lactic streptococci. The body is sour-cream-like and slightly viscous. Lactobacillus delbrueckii subsp. bulgaricus and Lactic streptococci do most of the fermenting.
Snezhok usually has sugar or fruit-berry syrup added to the soured milk (ru.wikipedia).
Low risk.
Every number is labelled with how it is known. How this atlas is made
Developed in the USSR in the 1960s as an alternative to the unpopular Bulgarian yoghurt, and now made in large volumes across the CIS (ru.wikipedia, citing Tovarny slovar vol. 9, 1961).
