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.

Alcoholic drinks from India
Sunda kanji is a sour rice drink of the fishing communities on the Tamil Nadu coast. Parboiled rice is cooked, dried in the shade, mixed with a ground starter powder and four parts of water in a clay pot, and left for three days, then strained through a thin cloth. In the one study that measured it, the pH fell from 6.59 to 3.55 and 3.77 in the two versions.

Sunda kanji is a sour rice drink of the fishing communities on the Tamil Nadu coast. Parboiled rice is cooked, dried in the shade, mixed with a ground starter powder and four parts of water in a clay pot, and left for three days, then strained through a thin cloth. In the one study that measured it, the pH fell from 6.59 to 3.55 and 3.77 in the two versions. Made in 6 steps over 3.1 days – 3.2 days. The longest step, ferment, then strain through cloth, takes 3 days (Muthusamy T. and Manokaran A.P. 2022). Yeasts, counted at 36107 colonies on day 3 and confirmed as yeast by lactophenol cotton blue staining and microscopy does most of the fermenting.

Sunda kanji is a thin mash, four parts water to one of cooked rice, set with a ground herb and grain starter powder in a clay pot and strained after about three days, so it is drunk as a sour gruel, with its alcohol reading still rising on day 10, rather than kept as a beer.
The authors note that a pH this low holds back harmful bacteria such as coliforms and Enterobacteriaceae, citing earlier work, and they judged the drink fit to drink only up to the third day.
Every number is labelled with how it is known. How this atlas is made
The study's authors say the coastal people of Tamil Nadu long made and kept their own foods, and that sunda kanji was a cheap drink with medicinal value which Tamil people drank, but that most people now drink other drinks instead.
