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.
Turn your phone or webcam into a document scanner. Capture each page live, apply scanner filters (grayscale / B&W), get a multi-page PDF. Stays in browser.
Each capture is scanned for the page outline — edges are detected, the largest four-cornered shape wins, and a perspective transform straightens it into a flat, rectangular page. Shot at an angle, the result still looks scanner-flat. If no page outline is found, the full frame is kept, and you can switch auto-crop off for whiteboards or odd-shaped subjects.
Image to PDF takes image FILES already on your device. Scan to PDF turns your camera into a live scanner — you capture pages on the spot, no separate photo-then-upload step. Better for mobile.
Mimics a document scanner. Adaptive threshold turns the page into pure black/white — text becomes crisp, shadows and yellowing disappear, file size drops. Best for paper documents.
Yes, if your laptop has a webcam. The "environment" facingMode preference helps mobile pick the rear camera; desktop falls back to whichever camera is available.
No. Camera frames stay in your browser. The PDF is built locally with pdf-lib. Nothing leaves your device.
