Can You Translate InDesign Files Without Breaking the Layout?
This page is for designers, marketing managers, and production leads who are commissioning a multilingual version of an InDesign document and want to understand what happens to the layout during translation. It covers how the DTP translation process works, what file types are supported, how text expansion is managed, and what to expect when working with non-Latin scripts — including Arabic, Mandarin Chinese, and Japanese.

Frequently Asked Questions
Can you translate an InDesign file and return it in the same format?
Yes. LingvoHouse accepts native InDesign files — both .indd and .idml formats — translates the content, and returns the file in the same format with the layout intact. The translation workflow extracts text from the source file into a CAT tool, handles translation and review, and then places the translated text back into the original InDesign document. Paragraph styles, character styles, master pages, and image placement are preserved throughout. The client receives editable InDesign files alongside press-ready PDFs if required.
What actually happens to the layout when text expands in translation?
Text expansion is managed during the typesetting stage, after translation is complete. When content is translated from English into French or German, body text typically expands; the DTP specialist adjusts text frame dimensions, tracking, and point size to accommodate this within the existing design structure. LingvoHouse works within the original paragraph and character styles rather than overriding them, which preserves the visual hierarchy of the document. Where expansion is significant enough to affect the design in a way that requires a client decision — a heading becoming two lines, for instance — the project manager flags this before finalising, not after delivery.
Which file formats does LingvoHouse accept for multilingual DTP projects?
LingvoHouse accepts InDesign (.indd, .idml), Illustrator (.ai), PDF, PowerPoint (.pptx), Word (.docx), and Publisher files. Native source files always produce the cleanest DTP result, because the text is fully editable and the layout can be adjusted precisely. For PDF-only projects where no InDesign source exists, work can proceed directly from the PDF, though the project manager will note any limitations at the assessment stage. Supplying the native file wherever possible reduces both turnaround time and the risk of layout inconsistencies.
Can machine translation be used for InDesign documents to speed up the process?
Machine translation alone is not appropriate for branded documents, marketing materials, or any content where tone, terminology, and presentation quality matter. LingvoHouse uses human translators for all DTP projects, working under an ISO 17100-certified workflow that requires translation followed by independent review. Machine translation post-editing (MTPE) is available for high-volume, lower-sensitivity content where the client specifically requests it and understands the quality trade-offs — but it is not the default, and it is not recommended for client-facing brochures, annual reports, or campaign materials.
How are non-Latin scripts such as Arabic, Mandarin Chinese, or Japanese handled in InDesign?
Each non-Latin script requires specific technical handling in InDesign. Arabic and Farsi are right-to-left languages; LingvoHouse manages text direction, layout mirroring, and Arabic-specific OpenType features using the Middle Eastern or World edition of InDesign. Mandarin Chinese, Japanese, and Korean require font substitution where the source font does not include CJK character support, and careful tracking adjustment because these scripts typically condense relative to an English source. A post-typesetting linguistic review is carried out by a translator for each language version, confirming that no characters have been substituted incorrectly or lost during typesetting.
What is included in a multilingual DTP service — and what is not?
A multilingual DTP service from LingvoHouse includes text extraction, ISO 17100-certified translation and review, typesetting and layout adjustment, font sourcing or substitution for non-Latin scripts, a post-typesetting linguistic review, and delivery in the agreed file format. It does not include redesigning the source document, recreating charts or infographics from scratch, or supplying photography or illustration. If the source file has significant structural issues — missing fonts, uneditable PDFs, or broken links — the project manager will flag these at the assessment stage before work begins, so the client is not presented with unexpected work at the delivery stage.
How should files be packaged and supplied for an InDesign translation project?
Supply the InDesign file packaged using the InDesign Package function, which collects the .indd or .idml file, all linked images, and all fonts into a single folder. This prevents font substitution and missing-link errors during typesetting. If fonts cannot be supplied due to licensing restrictions, notify the project manager at the brief stage so alternatives can be identified in advance. Alongside the packaged file, supply the target languages, any existing glossary or brand terminology guide, and the delivery deadline. LingvoHouse confirms file receipt and raises any technical issues before translation begins.
How long does it take to translate and typeset an InDesign brochure?
Turnaround depends on word count, page count, language count, and file complexity. A 16-page brochure translated into French, German, Spanish, and Italian — including typesetting and post-typesetting review — is typically deliverable within five to seven working days. Projects involving Arabic, Mandarin Chinese, Japanese, or Korean may require additional time for right-to-left layout adjustment or CJK font handling. For time-critical projects, LingvoHouse can assess whether an accelerated timeline is achievable once the file and scope have been reviewed. Deadlines should be stated at the brief stage so the project manager can confirm feasibility before work begins.
For InDesign translation and multilingual DTP projects, submit source files and target languages via lingvohouse.com. LingvoHouse will assess the files, confirm the workflow, and provide a quote — with no obligation to proceed until the scope and timeline are agreed.

I was so impressed at the quick turnaround and the quality of the output. Not only was the text I provided translated into Bengali and Spanish but the formatting of the PowerPoint I shared was exactly as the English version, so I didn't have to tidy it up at all. I am really pleased with the service provided by LingvoHouse.

Reviews
I was recommended LingvoHouse by a colleague, and I am thrilled to say that choosing them was an excellent decision. LingvoHouse delivered an outstanding service from start to finish. Their team not only provided precise translations but also ensured that every technical term was thoroughly verified and appropriately localised for each target language.
Moreover, the project required full DTP (Desktop Publishing), and LingvoHouse produced beautifully designed translations, maintaining consistency and format across all languages, which was critical for the professional presentation of the manual.
Communication with LingvoHouse was seamless and efficient. They kept me informed throughout the process and were always responsive to any queries or concerns. Their professionalism and dedication made the entire experience smooth and hassle-free.
I am one happy customer!
They demonstrated a deep understanding of what brand's voice is and asked me questions to make sure their ideas were matching mine. Keyword research ensured that my content was not only accurately translated but also optimized for search engines in each target market, which initially was a pain for us and we were desperate to solve it. I just needed to boost our visibility and engagement across diverse regions, and this is exactly what they helped us to do.
We had a couple of catch up calls which gave me confidence as well as peace of mind.
Happy to recommend to anyone who requires professionalism, attention to detail, and prepared to be commited to deliver quality.
Super happy!
I couldn't recommend them more - special shout out to Federica and Charline - thanks so much!
