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.

Cheese from Finland
Leipäjuusto is a boundary entry with little or no fermentation. Warm pasteurised milk is set with rennet and salt, the curd is drained and pressed into a flat sheet 0.5–3 cm thick, and the sheet is baked or grilled until spotted brown on both sides. It is eaten fresh, squeaky and mild, often with cloudberry jam.

| Rennet | [pgi-pohjalainen][pgi-kainuu] |
| Salt0.33 % of the curd weight in one US make | [pgi-pohjalainen][lindstrom2025] |
| Calcium chloride0.04 % of a 32 % solution in one US make | [lindstrom2025] |
Total time across the recorded steps: 2.7 h
What changes: Salt and rennet go into warm pasteurised milk and it sets
Output: curd.

Leipäjuusto is a boundary entry with little or no fermentation. Warm pasteurised milk is set with rennet and salt, the curd is drained and pressed into a flat sheet 0.5–3 cm thick, and the sheet is baked or grilled until spotted brown on both sides. It is eaten fresh, squeaky and mild, often with cloudberry jam. Made in 5 steps over 2.7 h. The longest step, press into a flat sheet, takes 1.5 h (Lindstrom R 2025).

Leipäjuusto is a fresh rennet curd that is baked, not ripened, so it is a boundary entry. Its high pH (about 6.6) and added calcium keep it from melting, like halloumi. Paneer is set by acid, not rennet.
Both Finnish application texts name pasteurised milk and say the cheese is packed straight after baking and cooling. In the one US make the milk was pasteurised at 73 °C for 15 s, the baked cheese was aimed at 82 °C inside, and it was vacuum-sealed and stored at 4 °C.
Every number is labelled with how it is known. How this atlas is made
The Kainuu application says it was once made on nearly every farm there and that Kainuun Osuusmeijeri began industrial production in the 1960s. The Ostrobothnian PGI text quotes a 1928 Emäntälehti saying Christmas there did not feel like Christmas without leipäjuusto, and describes it as a festive food for feasts and work parties.
