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.

Fruit from Southern Thailand
Too-rian-prieo is durian flesh mixed with about 7 to 8 % salt and about 3 % sugar, packed in a bowl under cloth and left in the shade for 2 days. It is a semi-solid, strong-smelling condiment made at home in the south.

Too-rian-prieo is durian flesh mixed with about 7 to 8 % salt and about 3 % sugar, packed in a bowl under cloth and left in the shade for 2 days. It is a semi-solid, strong-smelling condiment made at home in the south. Made in 4 steps over 9 days. The longest step, store, takes 7 days (JIRCAS 2026). Salt is 7–8 % (JIRCAS 2026). Lactobacillus plantarum and other Lactobacillus sp. and Candida sp. do most of the fermenting.

The JIRCAS recipe mixes durian flesh with about 7 to 8 % salt and about 3 % sugar and ferments it for 2 days in an open bowl under cloth. A Malaysian paper describes tempoyak, a durian condiment of Malaysia and Indonesia, as durian with 2.5 % salt in a sealed container for 1 week [ahmad2018].
The JIRCAS card gives a storage life of 7 days. In a Malaysian study of tempoyak, a different durian ferment, Salmonella spp., Listeria monocytogenes and Staphylococcus aureus were not detected in the samples, but in a survival test these pathogens lasted up to 8 to 12 days; that study did not examine this product.
Hazards the sources name: Salmonella, Listeria monocytogenes and Staphylococcus aureus (tested in Malaysian tempoyak, a different durian ferment, not in this product; not detected there; in a survival test they lasted up to 8–12 days).
