The Ultimate Guide to PDF Translation: Say Goodbye to Formatting Errors and Garbled Text

If there is a 'most familiar stranger' in the world of digital documents, it has to be the PDF. We encounter it every day: product manuals, academic papers, business contracts, scanned documents... But the moment you try to translate it, this 'old friend' will immediately show you what true despair means.

Have you experienced any of the following:

• Have you ever tried to copy text from a PDF, only to find you can't select it, or that what you copy turns out to be complete gibberish?
• After finally extracting the text and putting it into translation software, when you paste it back, the images are gone, tables are distorted, and the formatting is completely ruined?
• When faced with scanned PDFs (which are essentially just large images), do you feel helpless, as if you've encountered an insurmountable technological barrier?

Don't be discouraged—the challenges you are experiencing stem from the very nature of the PDF format. The good news is that technological advancements have already provided us with an ideal solution.

Why is translating PDFs so challenging?

To address the issue, we must first understand the essence of PDFs. PDF (Portable Document Format) was originally invented to ensure consistent visual presentation across any operating system and device. It acts as a digital 'snapshot,' faithfully capturing the appearance of a printed document, but at the cost of editing flexibility. Want to learn more? Take a look at the official Adobe introduction to PDF.

When you attempt to translate a PDF, you are actually challenging its core design:

• Text extraction difficulties: In many PDFs, text is not a simple stream but consists of character blocks precisely positioned on the page, which can easily lead to errors during extraction.
• Separation of formatting and content layers: Style, layout, and text content are stored separately. Conventional translation tools only replace the text and cannot understand or reconstruct the complex relationships between them.
• Challenges with scanned documents: For scanned PDFs, the machine perceives only an image, not text. It is necessary to first use Optical Character Recognition (OCR) technology to 'translate' the pixels in the image into editable text—a process that itself may introduce errors.
