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.
View, measure, and repair CAD and 3D files — STEP, STL, OBJ, PLY, GLB, 3MF, DXF, and Gerber — right in your browser. Nothing uploads.
Vegetables from Taiwan
Jiang-gua (fermented cucumbers) is a popular traditional fermented food in Taiwan. A 2012 study isolated 103 lactic acid bacteria from jiang-gua samples and raw cucumbers. Samples made without soy sauce were dominated by Weissella cibaria and Leuconostoc lactis, and soy-sauce samples by Lactobacillus pentosus and L. plantarum.
A short entry: the sources we found record only what is said here about Jiang-gua itself. Its own sources do not record how it is made, so the steps and scenes below are those of Oiji (salt-brined whole cucumbers), the closest documented vegetables ferment, shown as a guide to the method, not as a record of Jiang-gua.
| Cucumbers | The raw substrate; 33 of the 103 lactic acid bacteria in the study came from the raw cucumbers[s1] |
| Soy sauce (some samples) | Samples with it were dominated by different bacteria than samples without it[s1] |
Total time across the steps of Oiji (salt-brined whole cucumbers): 2.5 days – 6 days
What changes: Whole cucumbers are packed in a jar and held down with a stone
Output: cucumbers packed tight.

Jiang-gua (fermented cucumbers) is a popular traditional fermented food in Taiwan. A 2012 study isolated 103 lactic acid bacteria from jiang-gua samples and raw cucumbers. Samples made without soy sauce were dominated by Weissella cibaria and Leuconostoc lactis, and soy-sauce samples by Lactobacillus pentosus and L. plantarum. Weissella cibaria and Leuconostoc lactis, the main bacteria in samples made without soy sauce and Lactobacillus pentosus and L. plantarum, the main bacteria in soy-sauce samples do most of the fermenting.
Whether soy sauce is added decides which lactic acid bacteria dominate (Chen et al. 2012).
