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.
Extract the audio from an MP4, MOV, WebM or MKV video and save it as MP3 or WAV, plus FLAC, M4A, OGG or Opus in most browsers. Drop several videos at once and get one ZIP back.
Drop the video on this page, choose MP3 or another audio format, and click Extract. The sound track is saved as its own file, ready to play, edit or share. There is nothing to install and no account.
Videos in MP4, MOV, WebM, M4V and MKV, up to 500 MB each. AVI files do not open; convert them to MP4 first. MP3 and WAV are always available, and FLAC, M4A, OGG and Opus appear when your browser can encode them, which current Chrome, Edge and Firefox do.
192 kbps suits music and most uses. 128 kbps is plenty for speech such as lectures or podcasts and makes smaller files. Choose 320 kbps, or WAV or FLAC for a lossless copy, if you will edit the audio further.
Yes. Drop all the videos together. Each one is extracted with the same settings and the results download as one ZIP.
The tool checks for an audio track before it starts and tells you when a video has none, so you never get an empty file.
