How To Use It
1. Go to the AI PDF Translator website.
2. Drag and drop your PDF file or click to upload it from your computer. The file size limit is 20MB. For larger files, you might need to split them first using their complementary PDF tools.
3. After uploading, the interface displays two dropdown menus for language selection. Choose your source language (the current language of your document) from the first dropdown. Then select your target language (what you want to translate into) from the second dropdown.
4. Click the “Start Translation” button to begin processing. The system adds your document to a processing queue and displays a progress indicator.
Simple text documents may finish in 5 minutes, while complex files with multiple images and formatting can take up to 7 minutes or slightly longer during high server load.
5. Wait for the translation to complete. The tool processes your document in the background and you’ll see progress updates on screen. Once finished, a download button appears. Click to download your translated PDF file, which maintains the original formatting with translated text.
6. For best results, use clean, clearly scanned PDFs if working with scanned documents. Handwritten notes or unclear elements may affect translation accuracy. If you have a large document, consider testing with a few pages first by splitting your PDF and translating a section to preview the output quality.

FAQs
Q: Can I translate scanned PDF documents or only text-based PDFs?
A: The tool processes both digital PDFs and scanned documents. However, scanned PDFs with poor image quality, handwritten notes, or unclear text may produce less accurate translations. For optimal results with scanned documents, use high-resolution scans with clear, legible text. The AI works better when the source material is clean and well-formatted.
Q: Will my translated document be the same size as the original?
A: File size may vary slightly after translation. Different languages have different character densities. Translating from English to German often produces longer text, while translating to Chinese typically produces shorter text. The tool attempts to maintain the layout, but some spacing adjustments occur naturally. The visual appearance stays similar but isn’t pixel-perfect identical.
Q: Can I translate the same document into multiple languages?
A: Yes, but you need to run separate translation jobs for each target language. Upload your document, select your first target language, complete that translation, then repeat the process with different target languages.
