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 inspect tokens, 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.
Make a free QR code for a link, Wi-Fi, contact, email, SMS or location. Add a logo and colors, test that it scans before printing, and download PNG or SVG. Codes never expire.
It is free with no account. The code stores your link or text itself rather than a short link to a tracking service, so it never expires and keeps working even if this site is offline.
The scan test reads your code with a real QR reader under four conditions, up close, printed 2 cm wide, with a shaky hand and in dim light, and names the most useful fix when one fails, such as more contrast, a smaller logo or a shorter link. Scan a test print with your own phone before a large run.
Add a PNG, JPG, WebP or SVG image and choose Small, Medium or Large. Error correction switches to High so phones can read around the logo, and the scan test shows whether it still reads. The logo is kept in both PNG and SVG downloads.
Choose Wi-Fi, enter the network name and password, and pick the security type. Tick the hidden option if the network does not broadcast its name. A phone that scans the code offers to join without typing the password.
A QR code can only hold text, such as a link, so it cannot carry the file itself. Put the image or PDF online first, for example in a shared cloud folder, copy its link, and make a Link QR code from it.
Switch to Check a code, then point your camera at it, drop a photo or paste a screenshot. It shows what the code does and, for links, flags look-alike names, link shorteners, bare IP addresses and unencrypted pages. It reads the address only and never visits it.
