Which languages are supported for document translation: How to choose the target language

Key points of this article

First determine what language the readers use to read, and then check whether the target language is available in the tool. Do not select the language the other way around.
The language list is based on the actual options available on the translation page. Do not judge whether a certain language is supported based on impressions or old information.
For minor languages, languages written from right to left, and Chinese, Japanese, and Korean characters, additional checks are required to ensure that the font, typesetting, and original text format are retained.
When the same material is intended for readers in multiple countries, it is easier to control terminology by generating and checking each language separately than mixing them in one document.
Machine translation results need to be checked for important content, especially numbers, proper nouns, legal and medical expressions.

Many people search for "language translation software supports various languages". What they really want to know is: can the document in their hand be translated into the language they need, and which one should they choose. Language problems may seem simple, but they are often exposed after uploading. For example, the wrong language is selected, readers cannot understand it, or the overall layout of a certain text is misaligned.

This article is written for people who want to turn over documents such as contracts, papers, courseware, instructions, etc. to others. We do not list the languages one by one, because the language list will change with product updates, and the actual options on the translation page shall prevail. Let me explain three things clearly here: how to judge which target language to choose, how to check whether it is suitable for this document after selecting it, and which languages need to be paid more attention to.

After reading this article, you will have a set of judgment procedures for language selection, know what to look for before uploading, and know where to check before submitting the translation.

Which language do you want to translate into? One sentence conclusion

One sentence conclusion: The target language is determined by the reader, and the tool is only responsible for telling you whether it can be done. Decide on readers first, then check support.

your situation	Recommended practices	reason
The document is only for domestic colleagues or clients to see	Select the reading language of the other party. If the original text is in a foreign language, select the Chinese translation.	Readers can read it directly, eliminating the need for secondary translation.
The same material needs to be sent to readers in multiple countries	Generate a separate copy for each language, do not mix them in one file	The terminology and formatting of each language should be checked separately.
Study or revise according to the original text	Select bilingual comparison output, and the translated text will be kept side by side with the original text.	Able to compare paragraph by paragraph to find omissions or mistranslations
The target language is a minority language or uses a non-Latin alphabet	First use a page or a paragraph to test translation and check the font and punctuation.	Typography and font problems are often visible on a small scale
Documents to be submitted to official bodies	After selecting a language, ask someone who understands the language to review key passages	Mistakes in contracts, medical and academic presentations are costly

How to check the language list? Why can’t I just look at the impressions?

Different tools and different periods have different lists of languages, and the number of languages circulated in online articles can easily become outdated. Before uploading, check the actual available target languages on the translation page. If the language you need is not on the list, don’t just choose a language with similar meaning. Instead, use a tool that supports that language, or leave it to a professional translator.

Also note that "supporting a certain language" does not mean "translating equally well in all professional fields." In the same language, the words used in legal, medical and daily explanations are very different. Choosing the corresponding style of the document (academic, legal, medical, technical, business, literary, etc.) affects the results more than simply changing the language.

The type of source text also affects the choice of language

Scanned PDF versions can be directly uploaded for translation. To determine if a PDF is a scan, you can use the mouse to select a piece of text: if you can't select it, you can only select the entire image—usually it's a scan. The clarity of the scanned copy affects the quality of the translation. If there are obvious identification errors in the translation, you can try a clearer original to retry.

Text direction and font should also be considered in advance. Arabic, Hebrew, etc. are written from right to left, and the layout needs to be checked page by page. The length of the translation also varies: the same content translated into different languages can vary greatly in length, so leave extra space between table cells and margins, otherwise text may spill over.

There are three common misconceptions:

Mistakenly thinking "being able to choose means the translation is equally good": Choosing a language only means the tool can handle it; the quality of the translation should still be verified based on content.
Mistakenly thinking "bilingual comparison means no need to check": The comparison version is easier to check, but readers still need to confirm paragraph by paragraph, especially numbers and names.
Mistakenly thinking "multiple languages can be mixed in one translation": mixing terminology causes terminology inconsistency and makes it difficult for readers to distinguish which paragraph is in which language; it is recommended to generate them separately.

📊 Core Comparison

Output method	Suitable for the scene	Caution is needed
Only the translated text is available	Delivered to readers for reading, with clear purpose of the document	There is no original text comparison; key paragraphs need to be checked separately
Bilingual comparison	Proofreading, teaching, and paragraph comparison with the original text	The pages are longer, so you need to pay attention to the correspondence when reading
Generated separately by language	The same material is distributed to readers in multiple countries or regions	Each language should be individually checked for layout and terminology

How to actually use it

First, write down the reader's reading language and the purpose of the document, such as "quotation sheet for German clients" or "English handouts for classroom students."
Upload files in omnidoc.top. The document format can be PDF (including scans), Word, PowerPoint, Excel, EPUB, Markdown, or subtitle files.
Select one of the target languages. Choose the corresponding style according to the document type (academic, legal, medical, technical, business, or literary). If multiple languages are needed, generate them separately.
Select output method: Bilingual review during proofreading, translation only for delivery.
After downloading, first check the first few pages to check whether fonts, punctuation, tables, formulas, and images are positioned correctly, and whether text overflows due to changes in length.
Verify numbers, dates, personal names, clause numbers, and technical terms item by item against the original text. Please review key paragraphs with someone familiar with the language before submitting them.

❓ Frequently Asked Questions (FAQ)

1. What if I can't find the language I need?

First, check if there are other writing styles in the same language in the list; some languages have writing habits from different regions. If you really don't have one, switch to a tool that supports that language or have a professional translator handle it; do not substitute with a similar language.

2. Will there be differences in the translation of the same language depending on how it is written in different regions?

There are differences, commonly found in word usage, spelling, and units of measurement. If readers are in a specific region, select the corresponding regional format (as provided on the page) and ask local readers to confirm the key terms.

3. Can scanned PDFs be directly translated?

You can upload translations directly. If there are obvious identification errors in the translation, it is usually due to insufficient clarity in the original; you can try a clearer scanned copy and retry. You can also use the desktop client's OCR function to process the text first, then check the translation.

4. Can the results of machine translation be delivered directly?

It is not recommended to submit your manuscript without verification. Numbers, dates, names, clause numbers, and technical terms must be itemized against the original text. Important documents should be reviewed by someone familiar with the language.

📝 Summary

The level of support for languages in the language translation software depends on the actual languages available on the translation page; But which one to choose should start from the reader's perspective. First, identify the reader's language, then check the language, style, and layout, and finally manually review key content to make the translation more reliable.
