What PDF Translate helps you do

Translate the text of a PDF into another language using the Haivix AI translation endpoint. The document text is extracted in your browser, then a portion of it is sent for translation and returned as plain text. The PDF layout is not rebuilt, so the translation arrives as a block of text you can copy.

The document text is sent to Haivix AI endpoints for translation. Do not submit confidential or regulated content.

How it works

A PDF stores positioned drawing instructions rather than flowing paragraphs, which is why editing one is different from editing a document. Page content, fonts, images and annotations are separate objects, and a page only carries a text layer if the producer wrote one. Most tools here rebuild or render the file in your browser with pdf-lib and pdf.js; the formats that need a full office engine, such as Word, Excel, PowerPoint, PDF/A and HTML, use the Haivix service and say so in their privacy note. Every tool writes a new file and leaves the original untouched. Because content is placed by coordinates, extraction often returns text runs in visual order rather than sentences, and columns or tables can arrive interleaved.

How to use PDF Translate

Load the PDF and wait for the local text extraction.
Type the target language.
Run the translation and wait for the AI response.
Copy the translated text into a document or editor.

When to use it

Understand a document written in another language.
Produce a rough translation for internal use.
Translate extracted text for further editing.
Get the gist of a foreign contract before a professional review.
Turn a foreign-language article into a working draft.
Translate a short PDF where layout fidelity does not matter.

When not to use it

Do not use it for legal, medical or official documents without human review.
Do not expect a translated PDF with the original layout.
Do not upload confidential text; the extracted content is sent to the AI service.

Example

A two-page English PDF returns a Spanish translation as plain text. Only the first 10,000 characters of the extracted text are sent, so a longer document is translated only up to that point. A scanned PDF with no text layer extracts little or nothing, and the translation is correspondingly empty.

What you can do with PDF Translate

Extract text from the PDF locally.
Translate into a language you type.
Return the translation as plain text.
Show how many characters were extracted.
Report the remaining AI requests.
Leave the original PDF unchanged.

Example: work on a copy and check the output

Keep the original file. These tools produce a download rather than editing in place, so a failed operation never damages the source.

Check whether the PDF has a real text layer before relying on extraction. A scan is an image, so text tools return little or nothing until OCR has run.

Unlock encrypted files first. A password-protected PDF cannot be reordered, cropped or annotated until it has been opened with the correct password.

Review the output before sending it on. Fonts can substitute, overlays do not always remove what is underneath, and page boxes can shift content near the edges.

Note the page size and orientation before laying anything out. A mixed document can contain portrait and landscape pages, and a tool that assumes one size may crop or offset the others.

Keep a note of the operation and its settings. If a recipient questions the result, reproducing it from the original is faster than guessing which options were used.

What to know before you start

Machine translation is approximate and not suitable for legal or official documents without review.
The extracted text is sent to Haivix AI endpoints and usage is limited per day.
Only the first 10,000 characters are translated, and the output is plain text without the PDF layout.
Scanned documents need OCR before translation can work.

Common mistakes

Expecting a formatted translated PDF.
Uploading a scan with no text layer and getting an empty result.
Ignoring the 10,000-character limit on long documents.
Treating machine translation as a certified translation.

Troubleshooting

If the translation is empty, the PDF may be a scan or the text layer may be missing.

If only the first part is translated, the document exceeded the character limit.

If the request fails, the AI quota may be exhausted; check the remaining count.

If the language is not recognized, use the English name of the language.
