idmly vs Markzware PDF2DTP
Last updated June 2026 · by Kelly Fraser, maker of idmly
idmly and Markzware PDF2DTP both get content into editable InDesign, but they start from opposite ends. PDF2DTP converts a finished PDF back into InDesign (a paid plugin, typically from around $199/year). idmly converts a live HTML/CSS design into a native .idml ($49 once, web-based).
If your only source is a PDF, PDF2DTP is your tool. If you have the HTML, idmly is cleaner, because it never round-trips through a flattened PDF.
I'll be straight, because I make idmly and you can smell a rigged comparison. These two aren't really fighting over the same job. The honest question isn't "which is better," it's "what's your starting file."
The core difference: where you start
Markzware PDF2DTP (and its newer standalone sibling, PDFMarkz) takes a PDF and reconstructs it as InDesign content. It's genuinely good at recovering text, tables, colours and images from a finished file. But it's working backwards from a flattened document, so results depend on what the PDF preserved, and usually need a cleanup pass.
idmly takes the HTML of a live design, an AI-generated layout, a coded page, a browser export, and builds the InDesign file directly from the rendered layout. There's no PDF in the chain, so the structure is created fresh rather than recovered.
| idmly | Markzware PDF2DTP | |
|---|---|---|
| Source file | HTML / CSS design | Finished PDF |
| Output | Native .idml | InDesign document (in-app) / IDML via PDFMarkz |
| Where it runs | Web, nothing to install | InDesign plugin / standalone app (Mac, Windows) |
| Editable result | Clean, built from the live layout | Editable, often needs cleanup |
| Fonts & styles | Bound by name, real named styles | Recovered from the PDF, can be substituted |
| Pricing | $49 once, lifetime | From ~$199/year (one-time options exist) |
| Best for | AI, web and coded designs you have as HTML | Recovering content from PDFs you can't re-make |
When Markzware PDF2DTP is the right call
If the only thing you have is a PDF, a client sent one, you're reviving an old print job, the original design is long gone, PDF2DTP or PDFMarkz is the tool that fits. idmly can't help there, because it doesn't convert PDFs.
When idmly is the right call
If your design exists as HTML, made in an AI tool, coded by hand, or exported from the browser, idmly gives you a cleaner result for far less: a native .idml with real named styles and editable charts, no PDF round-trip, no subscription, and nothing to install. The first two pages convert free so you can judge it on your own file.
