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.
Overlay two PDF revisions and catch every changed pixel — plus word-level text, metadata, and form-field diffs, with drag-rect exclusion zones. Built for dense AEC drawings.
LaunchSide-by-side or overlay PDF diff with a document-type selector — Document (contracts, reports), AEC / Blueprint (drawings, schematics), or Image-Scan. Highlights pixel-level differences plus a word-level text diff in a modal.
Drop a Gerber X2 + Excellon ZIP and inspect every layer — compare revisions, snap-to-pad measure, probe trace widths, preview the board in 3D, and share a snapshot URL.
LaunchOpen RS-274X / X2 Gerber and Excellon files. Inspect layers, measure traces, export to PNG / SVG / DXF.
Open a .step / .stp part and it detects the holes, fasteners + BOM, wall thickness, draft, undercuts, sharp corners, and mass automatically. Measure point-to-point, section it, export a PNG. Built on the open-source truck Rust kernel.
LaunchOpen a STEP / STP part and it measures itself — holes, BOM, wall thickness, draft + undercut checks, and mass, detected automatically. Measure, section, screenshot. Rust + WASM B-rep kernel, runs in your browser.
Compress, merge, split, convert, and manipulate PDF files.
Resize, compress, convert, and transform images.
Format, encode, decode, and validate code and data — safe for production secrets.
Convert, compress, and cut audio and video — MP3, WAV, MP4, WebM, Opus — all in your browser, nothing uploads.
Recipe scaling, canning processing times — kitchen math you should not memorize.
AES-256 file encryption and self-destructing encrypted notes.
Analyze packet captures and run sysadmin diagnostics in your browser — nothing uploads. PCAP Analyzer ships first.
Chart-overlay technical analysis and precision financial math — your screenshots and numbers never leave your device.
Open CAD, BIM, medical, and enterprise files without paying $300-30K/year for the native software. Gerber Viewer ships first.
Send a file, clipboard, or snippet from your phone to your laptop and back — directly in the browser. Nothing is uploaded. No app, no account.
No. Drop connects your two devices directly in the browser over WebRTC. The bytes flow straight from one device to the other, encrypted with DTLS, with no relay and no storage. There is no server in the path — open your browser's Network tab and watch it stay empty during the transfer.
Drop only uses a direct connection (there is no relay), so some networks block it. Put both devices on the same Wi-Fi, or turn off any VPN, and try again. On different networks, switch on 'Over the internet' before pairing — though strict corporate or cellular firewalls can still prevent a direct link.
Any recent Chrome, Edge, Firefox, or Safari on desktop or mobile. Pairing uses the camera to scan a QR code, with a paste-the-code fallback when there is no camera. Saving large received files straight to disk works best in Chrome and Edge.
Sending streams the file from disk, so large files work — just keep the tab open until it finishes. The transfer is chunked and integrity-checked, so a dropped connection fails clearly instead of handing you a corrupt file.
Drop is built for your own devices: pairing needs a code that one device shows and the other scans, so a stranger can't connect without it. There is no public directory and nothing is stored. You are responsible for what you send.
