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.
Remove the sound from MP4, MOV, WebM and MKV videos in seconds. The video is copied, not re-encoded, so the quality and resolution stay exactly the same. Several clips at once, up to 4 GB each.
No. The video stream is copied into the new file packet for packet, without decoding or re-encoding it, so the picture, resolution, frame rate and bitrate are exactly what you started with.
Drop the .MOV from your iPhone, including HEVC clips, and you get a silent .mov back with the same rotation. Pick MP4 under Save as if the app you share to prefers MP4; that is a lossless copy too.
Removing the track gives the smallest file and suits social posts and screen recordings. Some course platforms, TVs and video editors reject a video with no audio stream; choose Silent track for those.
Every audio track is removed, including alternate languages and commentary, so the result is fully silent.
Not here. Muting a section means re-encoding the audio around it, and this tool only removes or replaces the whole soundtrack so the file stays lossless.
Up to 4 GB per file. The silent copy is written to your browser's own storage instead of memory, so large clips work on an ordinary laptop. Browsers without that storage handle up to 600 MB.
