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 Eastern Visayas, Philippines
Bahalina is tuba, coconut sap fermented with chopped red mangrove bark (barok or tungog), that has been racked off its sediment week by week and then aged for a year or more. The bark turns the sap red and astringent, and with time the wine grows stronger, from about 7 % alcohol fresh to about 10–14 %. Made in 5 steps over 12 months. The longest step, age into bahal and bahalina, takes at least 12 months (Agaton S.I.G. 2022). Yeasts, which outnumbered bacteria in fresh tuba does most of the fermenting.

What changes: Sap drips from the sliced coconut flower spathe into a tied-on container
The containers are tied on early in the morning and the sap is gathered at the end of the day. Output: fresh coconut sap.

Plain palm wine is drunk within a day or two and soon sours. Bahalina adds tannin-rich mangrove bark, is racked clear and is aged in jars filled to the top for a year or more, so it keeps and grows stronger.
Every number is labelled with how it is known. How this atlas is made
Tuba gathering is a daily trade in Leyte, passed down by gatherers (mananggiti) who tap in the morning and sell the sap in the afternoon. Aged bahalina once went into glass demijohns; most makers now use plastic jugs.
