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.

Try clearing filters or adjusting your search — most categories have dozens of tools once you widen the net.
View, measure, and repair CAD and 3D files entirely in your browser. Drop a STEP or DXF from an engineering handoff, an STL before a 3D print, an OBJ, PLY, or GLB from a scan or game pipeline, a 3MF from your slicer, or a Gerber fab archive for a PCB — and open it without installing the native software. The viewers share a WebAssembly CAD engine built for correctness: real B-rep tessellation for STEP, point-to-point and edge measurement, radii and angles, part trees with named bodies. The Mesh Fixer repairs the mesh problems that break prints — holes, flipped normals, non-manifold edges — locally. WASM bundles lazy-load on first drop so the rest of the site stays fast, and every file stays on your device: CAD models, board layouts, and scan data are exactly the files that should not sit on a stranger's server. Viewing is read-only by design — pan, zoom, orbit, measure, inspect, export — with real editing left to the native tools.
Today: STEP (.step/.stp), STL, OBJ, PLY, GLB/glTF, 3MF, DXF, and Gerber/Excellon fab archives. The Mesh Fixer also repairs common mesh formats before 3D printing. New formats land as their parsers stabilise.
Viewing is read-only by design — pan, zoom, orbit, measure, inspect, and export. The exception is the Mesh Fixer, which repairs meshes (fills holes, fixes flipped normals and non-manifold edges) so they print cleanly. Real editing belongs in the native software.
These formats normally require the native application just to look at a file. The point of this category is opening them in a browser tab — no install, no account, and the file never leaves your device. Filing them under generic image utilities would bury that.
