Taia translates Adobe InDesign IDML files directly, with no conversion step, because IDML (InDesign Markup Language) is already a native, editable XML format. AI or a professional linguist translates the text in place using your translation memory, glossary, and style guide, and the file comes back with its text frames, layers, master pages, and paragraph and character styles exactly where you left them.
How Does InDesign IDML Translation Work?
Translating an IDML file takes three steps, and — unlike a PDF — none of them involve converting the file to a different format first.
- Export IDML from InDesign and upload it at translate.taia.io. IDML is InDesign’s XML-based interchange format, so Taia reads the file directly — there’s no intermediate conversion step like the one PDF files require.
- AI or a professional linguist translates the text in place, using your translation memory, glossary, and style guide as reference, so terminology and tone match your previous translations.
- Download the translated IDML file and open it in InDesign. Text frames, layers, master pages, and styles carry straight through, because translation happens at the segment level — only the text is replaced, not the surrounding layout structure.
Because IDML doesn’t need converting first, this is a direct, native translation, not a reconstruction — the same advantage native formats like DOCX and PPTX have over PDF.
What Gets Preserved When You Translate an IDML File?
A translated IDML file keeps the original document’s layout because only the text inside each frame is replaced — the frames, layers, master pages, and styles around that text stay untouched. This is a native translation, not a rebuild of the design.
- Text frames: Each text frame keeps its position, size, and shape; only the text inside it changes.
- Layers: Layer structure and layer order are preserved exactly as they were in the source file.
- Master pages: Master page layouts and any elements inherited from them stay applied after translation.
- Paragraph and character styles: Named styles carry over, the same way they do in a DOCX file, so headings and body text keep their formatting.
- Linked images: IDML typically references linked image files rather than embedding them, and translation doesn’t touch those links — images stay linked to the same files and need to be relinked in InDesign the same way they would after any file move, not because of translation.
One honest, InDesign-specific caveat: translated text can run longer or shorter than the source language, and because InDesign text frames are often a fixed size, this can cause text overset. Text overset is InDesign’s own term for text that no longer fits its frame and gets visually cut off, shown in InDesign with a red plus icon on the frame. [NEEDS DATA: language-pair-specific expansion/contraction figures] — as a general rule, some target languages produce longer text than the English source, which increases the risk of overset in a frame that was sized for the original text. This is worth checking in InDesign after translation, especially on frames with little extra space — see “What is text overset, and does it happen with IDML translation?” below.
AI vs. Professional Translation for InDesign IDML Files
Use AI translation for internal layout drafts or fast-turnaround design iterations; use professional translation for client-facing brochures, packaging, or any InDesign project where a linguist should review terminology and phrasing before a designer finalizes the layout. Both options translate the same uploaded IDML file, so there’s no need to convert or re-upload anything to switch between them.
Instant AI translation is subscription-based. Every plan shares the same translation memory, glossary, and style guide:
- Free — 5,000 words/month
- Basic — €9/month, 20,000 words/month
- Pro — €39/month, 100,000 words/month
- Enterprise — custom pricing
IDML translation requires the Pro plan or higher — unlike Word, Excel, or PowerPoint, InDesign IDML is not included in Free or Basic, since it’s one of the specialized localization formats reserved for Taia’s top AI subscription tier.
Professional translation is always pay-per-word, never a subscription. Three tiers are available, all combining machine translation with human post-editing:
- Essential — one linguist reviews and edits the machine translation, from €0.06/word
- Enhanced — a translator plus a revisor, ISO 17100-certified process, from €0.09/word
- Ultimate — full TEP (translation, editing, and proofreading by three separate linguists), from €0.12/word
Professional translation is especially worth it for InDesign projects going to print, where a linguist reviewing the translated text inside the actual layout can catch both terminology issues and text-overset problems before the file goes to a printer.
How Much Does It Cost to Translate an InDesign IDML File?
AI translation of an IDML file is included in your subscription starting with the Pro plan; professional translation is billed per word on top of that subscription, with no separate “InDesign fee.” For AI translation, that means the Pro plan (€39/month for 100,000 words) or custom Enterprise pricing — Free and Basic don’t include IDML. For professional translation, that means from €0.06/word (Essential), from €0.09/word (Enhanced), or from €0.12/word (Ultimate), scaled to the word count of translatable text extracted from the IDML file.
Taia is an AI-first localization platform that combines instant AI translation in 204 languages and 65+ file formats, a built-in CAT editor and translation management system (TMS), and ISO 17100-certified professional linguists — with translation memory, glossary, and style guide shared across all three. IDML translation runs on the same platform, so a translated InDesign file has access to every one of those resources, including the translation memory that keeps terminology consistent across recurring publications like catalogs, packaging, or annual reports.
Neither DeepL nor Google Translate can translate an IDML file at all — both are limited to a handful of office formats, so InDesign projects have to be exported to Word or PDF first, which loses the native layout preserved here. See the AI Translator for the AI side of IDML translation, or professional localization services for the human side.

Frequently Asked Questions
Can an InDesign IDML file be translated?
Yes. Upload an IDML file at translate.taia.io and it’s translated directly, with no conversion step, using AI or professional linguists. The translated file comes back as an IDML you can open directly in InDesign.
Do I need to export IDML, or can I upload the native .indd file?
Export IDML. IDML (InDesign Markup Language) is InDesign’s XML-based interchange format, built for round-tripping through translation tools — it’s a native, editable format, so no conversion step is needed before translation, unlike a fixed, print-ready format such as PDF.
Does the InDesign layout stay intact after translation?
Yes. Because IDML is a native, editable format, the text is translated in place inside the existing file. Text frames, layers, master pages, and paragraph and character styles all stay exactly as they were — only the text changes.
What is text overset, and does it happen with IDML translation?
Text overset is InDesign’s term for text that no longer fits its frame and gets visually cut off, shown with a red plus icon on the frame. It can happen after translation because translated text can run longer or shorter than the source language, and InDesign text frames are often a fixed size. Checking for overset in InDesign after translation is the recommended step, particularly on frames with little extra space.
Are linked images affected by translation?
No. IDML typically references linked image files rather than embedding them, and translation doesn’t touch those links — the image references carry over into the translated file exactly as they were in the source.
Is InDesign IDML translation included in the free plan?
No. IDML translation requires the Pro plan or higher. Taia’s Free and Basic plans cover office and developer formats; the Pro plan adds IDML along with XLIFF and other specialized localization formats.
How much does it cost to translate an InDesign IDML file?
AI translation of an IDML file is covered by the Pro plan (€39/month for 100,000 words) or custom Enterprise pricing. Professional translation is billed per word, from €0.06/word for Essential, from €0.09/word for Enhanced, or from €0.12/word for Ultimate.
Can I get an InDesign project professionally translated by a human linguist?
Yes. Three professional tiers are available, all pay-per-word: Essential (one linguist, from €0.06/word), Enhanced (translator plus revisor, ISO 17100-certified, from €0.09/word), and Ultimate (full TEP — translation, editing, and proofreading — from €0.12/word). This is especially useful for print-bound InDesign projects, where a linguist can review the translation inside the actual layout before it ships.
