Why can't I convert INDD to PDF online here?

INDD is Adobe's proprietary, closed file format. Only Adobe InDesign can open and read these files, and Adobe's licensing terms prohibit online services from converting INDD files for third parties without special licensing (InDesign Server or a paid commercial SDK). That is why no serious free online service offers reliable INDD conversion.

So how do I convert my INDD file to PDF?

If you have Adobe InDesign: open the file, choose File → Export, select "Adobe PDF (Print)" for printing or "Adobe PDF (Interactive)" for digital use, and save. It takes 5 seconds and produces perfect quality.

What if I don't have InDesign?

Your options: (1) ask the original designer to export the PDF for you, (2) try Adobe's 7-day free Creative Cloud trial, (3) try Photopea (a free web app that can open INDD — quality and reliability vary), or (4) hire a freelancer on Fiverr or Upwork for a one-off fee.

What is the difference between INDD and IDML?

INDD is InDesign's binary working file format. IDML is the documented, XML-based interchange format. But both can only be exported from InDesign — so if you do not have InDesign, IDML does not help either.

Once I have exported the PDF — what next?

That is where PDF.dk comes in. Use our prepress tools to make the PDF print-ready: outline fonts, add bleed and trim marks, compress for email/web, create N-up layout for professional printing, or convert to a CMYK colour profile. All free and no signup.

Is a PDF exported from InDesign immediately print-ready?

Almost — but not always. Printers often require: outlined fonts (so missing fonts don't cause errors), correct bleed and trim marks, CMYK colour profile, and optionally compression. Use PDF.dk's prepress tools for these steps after exporting from InDesign.

Why don't you just license InDesign Server?

At PDF.dk's current scale, the cost of an InDesign Server licence (or a commercial INDD-conversion SDK) — typically several hundred to several thousand euros per year — is not justified by the demand we see for this tool. We would rather be honest about the limitation than ship a brittle hack that fails when you need it most. If demand grows, we will reconsider.
