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.
Lines, arcs, splines, text, dimensions, hatches and blocks, rendered as SVG that stays sharp at any zoom. Toggle layers, open the paper layout, measure, export SVG or PNG.
Launch DXF Viewer
No. Drop the file on this page. The viewer reads the drawing in your browser, so you need no CAD program and no account. It opens DXF files saved from AutoCAD, LibreCAD, QCAD, FreeCAD, SolidWorks, Fusion, Inkscape and other drawing programs.
No. DWG is AutoCAD's own binary format, and this viewer reads DXF only. In AutoCAD, use Save As and pick a DXF file type, or run the DWG through a DWG-to-DXF converter, then open the DXF here.
ASCII DXF, the text form that AutoCAD and most programs write by default. Binary DXF is not supported, so save the drawing again as ASCII DXF if it fails to open. The viewer draws lines, arcs, circles, polylines, splines, ellipses, text, multiline text, dimensions, hatches, solids, 3D faces (seen from above), points and block inserts.
True 3D objects such as meshes, ACIS solids and regions, raster images, and leader lines. Pattern hatches show as a light solid fill rather than the pattern itself. When the viewer reads an object but cannot draw it, such as a hatch or a layout viewport it cannot parse, a notice in the side panel says how many were skipped.
Yes. When a file has a paper-space layout, switch from Model to Paper. You see the sheet with its title block and notes, and each viewport shows the model at its own scale.
Press M, then click two points. Each distance is listed in the Measure panel. Distances are in drawing units, the same numbers the drawing was made in. A DXF does not always record which unit that is, so check the title block when it matters.
Open the Export panel. Export SVG saves the current view as vectors you can scale or edit in Inkscape or Illustrator. PNG snapshot saves an image of the view. Print to PDF saves a one-page sheet with that image plus the entity count, layer count and drawing size.
No. The DXF is parsed and drawn in this browser tab, and the file never leaves your device. That makes it safe to open a client's drawing on a shared computer.
Yes. It runs in a current browser on Windows, Mac and Linux, and on phones and tablets, with nothing to install.
