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.

Meat from Vietnam
Thịt chua is the sour pork of the Mường of Thanh Sơn in Phú Thọ. Thin slices of pork are seasoned with salt and tossed in thính, a roasted, finely ground flour of maize, rice and mung bean, then packed into bamboo tubes lined and capped with guava leaves and left to sour for 4–7 days. No scientific study of it was found.
A short entry: the sources we found record only what is said here about Thịt chua itself.

Thịt chua is the sour pork of the Mường of Thanh Sơn in Phú Thọ. Thin slices of pork are seasoned with salt and tossed in thính, a roasted, finely ground flour of maize, rice and mung bean, then packed into bamboo tubes lined and capped with guava leaves and left to sour for 4–7 days. No scientific study of it was found. Made in 4 steps over 4 days – 7 days. The longest step, ferment, takes 4–7 days (Thuý Uyên 2025).

Thịt chua is coated in roasted flour (thính) and packed in bamboo tubes, while nem chua is minced pork with rind, wrapped in leaves and eaten after a short ferment.
This page records a practice; it is not a method to follow. The source describes raw pork sliced, packed and soured with no cooking step, and no study we found measures its pH, salt or pathogens. Raw pork can carry Trichinella worms. In northern Vietnam, five documented outbreaks among people who ate raw pork caused 126 confirmed cases and 8 deaths, and fermented nem chua from a wild boar was among the sources of one of them. CDC says curing, drying or smoking alone does not reliably kill the worms. Cook it through before eating.
Hazards the sources name: Trichinella spiralis, identified in muscle biopsies from patients of a 2012 outbreak in northern Vietnam traced to raw lap and fermented nem chua (a related Vietnamese sour pork) from a wild boar. Thịt chua itself was not tested.
