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.
LaunchOpen a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Compress, merge, split, convert, and manipulate PDF files.
Resize, compress, convert, and transform images.
Convert, compress, and cut audio and video — MP3, WAV, MP4, WebM, Opus — all in your browser, nothing uploads.
Simulate a canning process down to its F0 sterilizing value.
Encrypt files, share encrypted notes as links, and read passport IDs and Windows event logs.
Analyze packet captures, move files between devices, and console into network gear — nothing uploads.
Scan receipts into an expense ledger — your receipts and spending stay on your device.

Cereals and bread from Ecuadorian Andes
"Dry rice" (arroz seco) eaten at every meal in the highlands. The fermentation heat partly pre-cooks it, so it cooks faster at altitude, where water boils at about 87 °C at 3,000 m. Riboflavin is about double that of unfermented rice and a few per cent of the protein becomes soluble; no aflatoxin was found [VANVEEN1968]. Made in 4 steps over 13 days – 30 days. The longest step, turn and re-cover, takes 6–15 days (van Veen A.G 1968). Bacillus subtilis does most of the fermenting.
| Main step | 6–15 daysReported[VANVEEN1968] | Turn and re-cover |
|---|---|---|
| Temperature | 50–80 °CReported[VANVEEN1968] | Self-heating fermentation |
| moist unhusked (paddy) rice; thin-hulled varieties Fortuna and Carolina preferred, Chato-Canilla when short |
| Starter: spontaneous |
Total time across the recorded steps: 13 days – 30 days
What changes: Moist paddy is heaped under tarpaulins until it starts to heat
Output: paddy beginning to heat.
