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 Korea
Bogeo-sikhae is sikhae made with globefish (puffer). In a 2008 study it soured to pH 4.42 and lactic acid bacteria reached about 10^8 per gram by day 10, as they did in flounder sikhae made in the same study. Puffer can carry a deadly nerve poison, so this is not a home ferment.

Total time across the recorded steps: 20 days
What changes: Starting material: globefish (puffer) for sikhae
Puffer liver and ovaries hold a deadly toxin. Japan allows only approved handlers to remove the toxic parts. Do not clean puffer yourself.

Bogeo-sikhae is sikhae made with globefish (puffer). In a 2008 study it soured to pH 4.42 and lactic acid bacteria reached about 10^8 per gram by day 10, as they did in flounder sikhae made in the same study. Puffer can carry a deadly nerve poison, so this is not a home ferment. Made in 4 steps over 20 days. The longest step, ripen in the cold, takes 16 days (Kim Y.S 2008) and runs at 4 °C (Kim Y.S 2008). Lactic acid bacteria does most of the fermenting.

Puffer instead of flatfish. In the one study it soured to about the same pH as flatfish sikhae made alongside it, and tasters rated it second of the four seafood sikhae.
Not for home practice. Puffer can carry tetrodotoxin, a nerve poison that can kill by stopping breathing. It builds up most in the liver and ovaries, and how much a fish holds varies by species and body part. Japan's health ministry says rubbing with salt, soaking in water or heating does not remove it, and that untrained people must never prepare puffer. The Korean Food Code limits puffer toxin to 10 MU/g in flesh and in skin, and lists the puffer species that may be eaten as food. We could read only the abstract of the 2008 study. It reports microbial counts, pH, acidity and taste scores and mentions no toxin test, so nothing we read shows that this fermentation makes puffer safe.
Hazards the sources name: Tetrodotoxin, the puffer toxin and a nerve poison; the Korean Food Code limits it to 10 MU/g in flesh and in skin.
