How to Convert a Vector File with Vector Express

Updated

Vector Express converts vector files directly in your browser: open vector.express, make sure JavaScript is enabled, drop your file into the upload area, and download the converted result. It accepts AI, CDR, DWG, DXF, EPS, HPGL, PDF, PLT, PS, and SVG files. The site describes the conversion as free and also offers an API, with a separate pricing page for API details.

Before you start

  • A supported source file. The listed input formats are AI, CDR, DWG, DXF, EPS, HPGL, PDF, PLT, PS, and SVG. If your file is in another format, convert it to one of these first.
  • JavaScript enabled. The site states plainly that JavaScript is required to run the app, so a script blocker or a hardened browser profile will leave you staring at a blank page.
  • A stable connection and enough time for large files. Vector files with heavy geometry or many embedded objects take longer to process than a simple logo.

Step-by-step conversion

  1. Open the site. Go to vector.express. If you see a message about enabling JavaScript instead of the upload interface, turn JavaScript on for the site and reload.
  2. Add your file. Use the drop area labeled "Drop a file here," or click it to browse for the file on your device. The interface is built around a single drag-and-drop target, so one file at a time is the expected workflow.
  3. Choose the output format. Select the format you want the file converted to. Because the tool handles ten input formats, the practical question is usually which output your downstream software needs — for example, SVG for web use or a CAD-friendly format for drafting tools.
  4. Start the conversion. Trigger the conversion and wait for processing to finish. The page gives no fixed time estimate, so treat duration as dependent on file size and complexity.
  5. Download the result. Save the converted file to your device, then open it in the target application to confirm geometry, layers, and text survived the conversion.

What to check after converting

Conversion between vector formats is rarely lossless in every respect. Verify these before relying on the output:

Check Why it matters
Paths and shapes Some formats handle curves and compound paths differently
Text Fonts may be substituted or converted to outlines
Layers and groups Layer structure often does not map one-to-one between formats
Colors Spot colors and gradients may shift or flatten
Units and scale CAD-oriented formats can carry different unit assumptions

If something looks wrong, try a different target format — for instance, SVG output for editing versus PDF output for sharing — rather than assuming the source file is broken.

Common snags

  • Blank page or no upload area. Almost always JavaScript being disabled or blocked.
  • Unsupported file rejected. Confirm the extension is one of the ten listed formats; anything else needs a prior conversion.
  • Large or complex file stalls. Reduce complexity in the source application first, or split the artwork.
  • Output opens but looks different. Expected in cross-format conversion; check the table above and adjust the target format.

If you need this repeatedly

Vector Express also offers an API, and the site points to its pricing page and documentation for details. That is the route to take if you are converting files programmatically or in batches rather than one at a time through the browser. Pricing and access terms for the API are set out on the site's own pricing page — check there rather than assuming the browser tool's free status extends to API use.
