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.
Shrink MP4, MOV, MKV, or WebM video on your laptop without installing CapCut or Handbrake. In-browser compression — fits files under email, Slack, or Discord size limits.
For one-off desktop compression, this is faster — no install, no signup, no admin permissions on your work laptop. CapCut is mobile-first and Handbrake is overkill for "make this MP4 small enough to email." Reach for those if you need ongoing editing or batch encoding.
Pick a target size and the tool back-solves the bitrate from the video length to land under it — Discord's free tier is 25 MB, Gmail attachments are 25 MB, Slack free is 1 GB. Switching to a smaller resolution (720p / 480p) shrinks the file further.
MP4, WebM, MOV, and MKV up to 500 MB. AVI files do not open.
Typical compression reduces file size by 40-70% with minimal visible quality loss. Bigger gains come from also dropping resolution.
Up to 500 MB. Processing happens locally on your device, so its memory is the only other constraint.
