Frequently Asked Questions
How much does document translation cost?
The cost of document translation varies significantly. Factors influencing price include the language pair, the document's complexity, the length of text, and the service provider's pricing model (per word, per page, etc.). Automated translation is typically the most affordable, while professional human translation with specialized subject matter expertise is the most expensive.
How quickly can a document be translated?
Turnaround time depends on the chosen method. Automated translation offers instant or very quick results. Human translation turnaround times range from a few hours to several days or weeks, depending on document size, complexity, and translator availability. Rush services are often available at an extra cost.
When should I use automated versus human translation?
Different document translation services cater to varying needs. For simple translations or quick information retrieval, automated services are adequate. For critical documents that require high accuracy, legal or technical documents, or marketing materials, human translation by qualified professionals is essential.
What file formats are supported for translation?
Many document translation services support a wide variety of file formats, including Microsoft Word documents (.doc, .docx), PDF files, text files (.txt), spreadsheets (.xls, .xlsx, .csv), HTML, and others. Always confirm compatibility before submitting a document.
