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.

Fish and seafood from Philippines
Balao-balao is whole shrimp salted, drained and mixed with nearly five times its weight of cooked rice, then sealed in jars for a week or so. Lactic acid bacteria turn the rice sugar into acid, the pH falls from about 7.5 to 3.8, and the shells turn red and soft. It is sautéed with garlic and onion before eating. Made in 5 steps over 7.1 days – 10 days. The longest step, pack in wide-mouth jars and ferment, takes 7–10 days (Sanchez P.C. 1999) and runs at 28 °C (Sanchez P.C. 1999). Salt is 20 % (Sanchez P.C. 1999). Leuconostoc mesenteroides and Pediococcus cerevisiae do most of the fermenting.

Balao-balao is the shrimp form of burong isda. Both are lactic ferments of seafood with cooked rice, but balao-balao uses whole shrimp and much more rice, about 4.8 parts rice to 1 part shrimp.
Lactic acid brings the pH down to about 3.8 within 10 days, and the product is cooked before eating. No safety study of balao-balao was found.
