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.

dry sour balls used as a meat substitute in vegetable stews; dried sigda 440 g/kg crude protein with sesame's high sulphur amino acids; lysine most limiting [Elfaki1991]. Made in 3 steps over 3 days – 7 days. The longest step, ferment sealed, remix, takes 3–7 days (Dirar H.A. Leaf and Seed Fermentations of Wes…) and runs at 30 °C (Dirar H.A. Leaf and Seed Fermentations of Wes…). Pediococcus sp. and Streptococcus sp. do most of the fermenting.

Total time across the recorded steps: 3 days – 7 days
What changes: Sesame press cake is ground to a paste with warm water and potash
Output: sigda paste.
Microbes at work in this step
raw cake carries Pediococcus, Streptococcus, Saccharomyces and Candida

An acid (lactic) seed ferment, unlike the alkaline Bacillus seed condiments of West Africa.
An acid (lactic) seed ferment, unlike the alkaline Bacillus condiments; the pH drop to ~4 is the main safety barrier.

Documented in Dirar's work on Sudanese ferments; grouped with kawal and furundu as solid-state meat substitutes made from cheap protein-rich plant materials. Furundu's fermentation is intermediate between sigda (acid) and kawal (alkaline) [Elfaki1991 summary].
