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.

Sauces and condiments from Mesopotamia
Šiqqu was a fermented sauce of fish, and sometimes of locusts or shellfish, that Mesopotamian households bought and stored like vinegar. Cuneiform letters, word lists and medical texts name it, but no surviving text says how it was made, so the steps below are a reconstruction.
| Fish | [cad] |
| Locusts | A medical text names šiqqu made with locusts[cad] |
| Shellfish and grasshoppers | Named in a popular account of the Yale culinary tablets[aramco1988] |
What changes: Fish or locusts are packed into a pot (reconstruction)
Reconstruction. The ingredients come from the texts; no text describes the method. Output: packed fish or locusts.

Šiqqu was a fermented sauce of fish, and sometimes of locusts or shellfish, that Mesopotamian households bought and stored like vinegar. Cuneiform letters, word lists and medical texts name it, but no surviving text says how it was made, so the steps below are a reconstruction.
Roman garum is known from detailed recipes. Šiqqu is far older and known only from its name, its pots and its uses, so how it was made is a guess.
No surviving text records how Mesopotamians kept šiqqu safe. As a general hazard of salted or fermented fish, the FDA says spores of Clostridium botulinum are very common in the gills and viscera of fish, and that fish preserved by salting, drying, pickling or fermentation should be eviscerated first, because without it toxin can form during the process even with strict temperature control. The steps here are a reconstruction, not a recipe to follow.
Every number is labelled with how it is known. How this atlas is made
The Chicago Assyrian Dictionary defines šiqqu as garum, a brine or sauce made of fish or locusts, attested in Old, Middle and Standard Babylonian texts. It was a household staple paired with vinegar, bought for dates in a Middle Babylonian record, and used in medicine. A popular account of the Yale culinary tablets of about 1700 BC says cooks made it from fish, shellfish and grasshoppers.
