CAD, BIM and drawing file converters

Drop a DXF and get a PDF sheet back. The drawing is parsed and rendered inside your own browser tab, so the file never leaves your machine — which matters when the drawing is under an NDA.

Turn CAD geometry into a web-ready vector you can drop straight into a website, a report or Figma. Lines stay lines, so the result scales without pixelation.

Get a clean raster preview of a DXF for a proposal, an email or a portfolio page. Rendered locally in the browser at high resolution.

DWG is a closed binary format, so no browser can read it and any site that claims to convert it in-page is uploading your drawing to a server. Here is how to do it correctly in AutoCAD — and how to get a browser-side conversion if the drawing is not confidential-critical.

DXF is the documented cousin of DWG: once a drawing is DXF, open-source tools, browsers and non-Autodesk software can read it — including the converters on this site.

Going the other way is simple, but the details decide whether the drawing behaves like a native one or like imported line spaghetti.

A PDF made from CAD contains vectors that can come back as geometry. A scanned PDF contains pixels and needs tracing. Knowing which one you have saves hours.

OBJ is one of the few 3D formats that is plain text and fully documented, so this conversion runs entirely in your tab: the mesh is parsed here and written out as DXF 3DFACE entities that AutoCAD, BricsCAD, Civil 3D and Revit all import. Nothing is uploaded and nothing is queued.

STEP carries real solids; DWG expects drawing entities. Nothing in a browser can read an ISO 10303 solid model, so every honest route runs through a CAD package — and which one you pick decides whether the DWG arrives as an editable 3D solid or as flat plotted linework.

IGES stores surfaces; STEP stores solids. Converting is not a re-save but a repair job: the surfaces have to be stitched into a closed body first, which is why the conversion belongs in a CAD kernel rather than in a web uploader.

Scan and print meshes often have to end up in a CAD drawing. This page parses the STL locally and writes each triangle as a DXF 3DFACE entity, which AutoCAD, BricsCAD, Civil 3D and Revit all import without a plug-in.

Illustrator artwork — logos, title-block graphics, site diagrams — often has to end up in CAD. AI is a PDF variant with private Adobe data, so the reliable route goes through a format both sides genuinely agree on.

Turn drawing sheets or a submittal PDF into lossless images, one per page, without uploading anything. Handy for marking up a sheet or pasting a detail into a report.

Render each PDF page to a compact JPEG, entirely in your browser. Good for renders, photo reports and anything headed into a slide deck.

Wrap an image into a PDF at its own pixel dimensions — the quickest way to send a screenshot, a detail crop or a scanned sketch as a document.

Turn a photo, render or scan into a one-page PDF locally. Nothing is uploaded, so site photos with client information stay private.

Rasterise a vector at a generous resolution for slides, documents and anything that will not accept SVG.

Put a vector graphic on a PDF page for issuing, printing or attaching to a submittal.

Shrink screenshots and renders for email and web use. Runs locally, no upload.

Re-encode a JPEG as PNG when a tool or template refuses JPEG input.

Cut image weight on a portfolio or company site. WebP keeps transparency and is typically 25–35% smaller than PNG.

Turn a downloaded WebP into a PNG that older software and CAD raster imports accept.

EPS is PostScript — a printing language, not a data format — so turning it into SVG means interpreting a program, which needs a PostScript engine rather than a browser tab. Inkscape does it free in two clicks.

IFC export is a mapping exercise, not a file conversion. The settings you pick decide whether the receiving team gets a usable federated model or a bag of generic solids.

Consultants who still work in AutoCAD need DWG. Done carelessly, the export arrives with 400 layers and hatches that will not plot; done properly it matches your office standard.

IFC holds a 3D model, DWG holds drawings — so this is a modelling-to-documentation step, not a file swap. There are three practical routes depending on what you need.

SketchUp exports DWG natively, but only in the Pro versions — and the export needs preparing if the result is going to be draftable.

FBX is a closed Autodesk scene container — meshes plus cameras, lights, materials and animation. OBJ is a plain mesh list. The conversion is a deliberate simplification, and the free tools that do it run on your desktop.

3DS is a 1990s mesh format with hard limits — 65,536 vertices per mesh and eight-character material names — which is why asset libraries full of 3DS files need converting before they are usable in modern visualisation or CAD work.

Both formats are openly documented plain text, so this conversion runs entirely in your tab: the OBJ vertices and faces are parsed here, polygons are triangulated and written out as ASCII STL with a computed normal per facet. Nothing is uploaded.

STL is documented in both its ASCII and binary forms, so this page reads either one on your machine and writes a Wavefront OBJ. Useful when a print-ready mesh has to go into a renderer or CAD package that will not take STL.

ASCII PLY — the format photogrammetry and laser-scan pipelines export — is plain text, so it is parsed and rewritten as Wavefront OBJ right here on your machine.

Turn an ASCII PLY scan mesh into print-ready ASCII STL without installing anything. The parsing and the facet-normal maths both run in your tab.

GLB is a documented container: a JSON chunk plus an optional binary buffer. Unpacking it back to readable .gltf is lossless, and it happens entirely in your tab — the binary buffer is embedded as a data URI so the .gltf file stands on its own.

SKP is a closed format, so no browser can read it. SketchUp itself exports OBJ — but which version you have decides the route, and there is a free path either way.

This is not a file conversion — it is a remodelling job. STL holds triangles, STEP holds exact solids and surfaces. Anything that claims a one-click STL to STEP is either wrapping the triangles in a useless faceted solid or rebuilding the shape for you.

FBX is Autodesk's closed scene format, so a browser cannot read it — but the conversion to glTF is well-trodden and free, and it matters because glTF is what web viewers and real-time engines actually want.

DAE is open XML, but a full COLLADA reader is a large piece of software — scene graph, transforms, skinning, libraries — so this is a job for Blender rather than a browser tab. It is free and takes about a minute.

X_T is the native transmit format of the Parasolid kernel, so only Parasolid-based CAD can read it. The good news: those packages all export STEP, and because both formats carry exact solids the conversion is genuinely lossless in geometry terms.

Both formats are open XML in WGS 84, so this is a direct, honest rewrite done on your machine: Google Earth placemarks become GPX waypoints, and paths become tracks with elevation kept where it exists.

Turn GPS tracks and waypoints into a KML you can open in Google Earth or hand to a client, without uploading survey data anywhere. Tracks become LineStrings, waypoints become Points, elevations are kept.

A shapefile is a set of files, carries a coordinate reference system and holds attributes as well as geometry — so this is a GIS-to-CAD translation, not a format swap. Getting the projection right matters more than the export itself.
