Can Adobe Acrobat translate a PDF, and how does Smartling handle PDF translation?

Adobe has added AI-assisted features to Acrobat, including document translation, as part of its broader generative-AI product push; exact language coverage and plan availability are controlled by Adobe and are best confirmed in Adobe's own documentation. Smartling does not offer a native Adobe Acrobat plugin. Instead, Smartling accepts PDF files directly and automatically converts each one to a Microsoft Word document for translation, so the finished translation downloads as a DOCX file rather than a PDF.

How does Adobe's PDF translation compare to other online translators?

Adobe's own PDF translation lives inside Acrobat as one of its AI Assistant features, while most other online PDF translation tools, including Smartling, handle a PDF by converting it to an editable format first rather than translating the PDF file structure directly. A few patterns explain why:

  • PDF is a fixed-layout, print-oriented format, not a structured content format. Most translation systems, Smartling included, convert a PDF to an editable document, commonly Word, before translating it, then hand back the translation in that converted format.
  • Password-protected PDFs can't be uploaded. This is a common limitation across PDF-handling tools generally, not specific to one vendor, and Smartling cannot accept a password-protected PDF for translation.
  • File directives aren't supported on PDFs. Inline instructions that control how a file is parsed work on formats like DOCX or CSV in Smartling, but not on PDF files, because a PDF's structure doesn't expose the same parsing hooks.
  • The original source file usually produces a cleaner result. Because a PDF is often exported from another format, Smartling recommends translating the original file, for example the InDesign or Word document a PDF was generated from, when it's available.
  • Scanned or image-based PDFs need OCR first. Text in a scanned PDF has to be extracted through OCR before it can be translated at all, a step that applies broadly across PDF-translation tools, not only Smartling's.

What should you check before translating a PDF at work?

  • Is the original source file available? An InDesign, Word, or similar editable source almost always produces a cleaner translated result than converting a PDF after the fact.
  • Is the PDF password-protected? Remove protection before uploading; Smartling, like most translation tools, cannot process a password-protected PDF.
  • Does the PDF contain scanned or image-based text? That text needs OCR before it can be extracted and translated, regardless of which tool is used.
  • Do you need the translated file back as a PDF, or is an editable format acceptable? Smartling returns a translated PDF as a DOCX file; if a final PDF is required, plan an export step back to PDF after translation and review.
  • Does the content actually belong in a design tool instead? If the "PDF" started life as an InDesign or Illustrator file, Smartling's native InDesign and Illustrator plugins handle the source format directly, which avoids the PDF conversion step entirely.

How can I translate a PDF using Adobe Acrobat, or through Smartling instead?

  1. Check for the original source file first - if the PDF was exported from InDesign, Word, or another editable format, locate that original file, since translating it directly through Smartling's InDesign plugin or a Word upload produces a cleaner result than a PDF conversion.
  2. Confirm the PDF isn't password-protected - remove any password before uploading, since Smartling cannot accept a password-protected PDF for translation.
  3. Upload the PDF to Smartling - Smartling automatically converts the file to a Microsoft Word document to make its text translatable, rather than parsing the PDF's own file structure.
  4. Route the content through AI or human translation - the converted document moves through Smartling's standard translation workflow, including AI Translation, AI-Powered Human Translation, or full human translation, the same as any other uploaded file.
  5. Download and, if needed, re-export to PDF - the finished translation downloads as a DOCX file; if the final deliverable needs to be a PDF, export the reviewed DOCX back to PDF as a separate step.

Cette approche convient aux équipes qui...

  • Occasionally need a PDF translated as part of a broader mix of file types already running through a translation workflow.
  • Have the original InDesign, Word, or similar source file available, or can get it, rather than only having a final PDF export.
  • Don't need Acrobat-specific PDF features, such as form fields or digital signatures, preserved through translation, since the file is handled as a converted document, not as a native PDF.
  • Already use Smartling for other content types and want PDF translation inside the same glossary, translation memory, and review workflow instead of a separate standalone PDF tool.

When PDF file translation may not be the right approach

  • Teams whose PDF was generated from an Adobe InDesign or Illustrator source file are better served translating that original file directly through Smartling's InDesign or Illustrator plugin, which avoids the PDF-to-Word conversion step entirely.
  • Teams that need Acrobat-specific PDF features, such as fillable form fields, digital signatures, or redaction, to survive the translation process untouched, since converting to Word for translation doesn't preserve those PDF-native elements.
  • Teams working from scanned or image-only PDFs with no editable original - those need an OCR step before translation, and results depend heavily on scan quality.

What are the best features to look for in a PDF or document translation tool?

Does it require the original source format, or can it work from a PDF alone?
Confirm whether the tool needs an InDesign or Word original for best quality or can only ever work from the PDF export.

What file format does the translated output come back in?
Ask specifically - Smartling, for example, returns translated PDFs as DOCX files, not as PDFs.

Can it handle password-protected or scanned PDFs?
Password protection and scanned or image-only content are common blockers; confirm what preprocessing, such as removing protection or running OCR, is required before upload.

Does the same platform also support the design tool the PDF originated from?
If the source is an InDesign or Illustrator file, a plugin for that tool usually produces a better result than converting the exported PDF.

Does the workflow apply the same glossary and translation memory used elsewhere in your content?
A standalone PDF tool with no shared glossary risks inconsistent terminology compared with the rest of a company's translated content.

How does Smartling handle Adobe PDF and Acrobat-related translation needs?

Smartling does not offer a native Adobe Acrobat plugin or connector - it isn't part of Smartling's published integration list, which includes Adobe Express, Adobe Creative Cloud, Adobe Experience Manager, Adobe Marketo Engage, and Adobe Workfront instead. For PDF files specifically, Smartling accepts a PDF upload and automatically converts it to a Microsoft Word document for translation, so the finished translation downloads as a DOCX file; directives aren't supported on PDF files, and password-protected PDFs can't be uploaded. Smartling recommends using the original file format when one is available, most commonly InDesign or Microsoft Word, since translating that source directly through Smartling's Adobe InDesign plugin (for IDML and INDD files) or a standard Word upload produces a cleaner result than converting an already-exported PDF.

For teams whose design and creative files already run through Smartling, native plugins exist for Adobe Illustrator and Adobe Photoshop, plus a certified, Adobe Technology Partner (Gold tier) integration for Adobe Express, so PDF conversion is often avoidable entirely if the original design file is still available.
