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.
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.
Launch Gerber Viewer
RS-274X (extended Gerber) and Gerber X2 attributes. Excellon and XNC drill files are auto-detected. Older RS-274D (no embedded apertures) is not supported.
.zip, .tar, .tar.gz, and .tgz. Loose .gbr / .drl / .gtl / .gbl files are also accepted.
Not yet. Gerber RS-274X / X2 plus Excellon are the MVP. ODB++ and IPC-2581 are on the roadmap.
Distances are computed in the file's native coordinate system (typically millimeters at 0.1 µm resolution). Pad-center snap is geometric (centroid of the aperture flash).
