Translate PDF.

The tool extracts usable PDF text when available. Missing or clearly corrupted text triggers OCR; enable Force OCR when a scan contains an incorrect text layer that still looks like plausible text. Set the source OCR language to match the scan and choose the language you want for translation.

One request processes one page or selected region with up to 25,000 source characters. The PDF is uploaded for processing; the extracted text from the chosen area is sent for translation. It does not translate every page automatically. Return to the workspace to choose another page or passage.

The source text stays visible while the translation is editable. Check names, specialist terms, quantities and context; errors in the source OCR can carry into the translation. Correcting the translation does not rewrite the source panel or original PDF.

Copy sits beside the translated text and copies its current wording with a brief fading effect. Direct edits update the TXT download. The blue Smart edit button opens a larger editor with AI actions, formatting and revision history. Review that work and use Apply Changes to bring its text back to the result.

Summarize text condenses a passage, Paraphrase text rewrites it, and Fix grammar requests language corrections. These actions replace the selected passage or, with no selection, the entire editor content. Suggest a title adds a heading above the document; a selected passage can guide the title without removing the body.

Each AI request accepts up to 600 words and 12,000 characters, with a 64-KB UTF-8 request limit. Select a shorter passage if a long result exceeds these limits. AI actions send that text to our servers only when you select Apply and request output in the same language.

Review proposed changes before keeping them. AI can omit details, alter meaning or introduce mistakes, especially when the input contains recognition errors. Undo returns to an earlier version. The main result is updated only after Apply Changes; running an AI action alone does not replace it.

Advanced editor provides paragraphs and three heading levels, sans-serif, serif and monospace fonts, font size, bold, italic and underline. Set text color or highlighting, use bulleted or numbered lists, adjust alignment and choose automatic, right-to-left or left-to-right direction. Clear formatting removes styling for a simpler result.

Formatting happens in your browser. Switching to Simple editor does not itself discard the advanced document; editing its plain text removes formatting. AI replacements insert unformatted text in the affected area, so apply final styling after reviewing the wording.

Use Formatted copy to keep this styling in an HTML download. Copy and Apply Changes transfer plain text. Formatting the result does not change the original PDF’s fonts, page layout or text layer.

Remove accents & vowel marks removes Latin accent marks and common Arabic vowel marks from the chosen passage or the whole editor. Normalize numbers standardizes Western, Arabic or Persian digit shapes according to the text’s script; it does not change their numeric values. These cleanup actions run locally in your browser.

Undo and Redo let you review editing steps, including AI changes. Restore OCR text or Restore translation returns the editor to the original result from processing. You can undo that restoration too. Cancel closes the window without applying its current changes to the main result.

Smart edit is a working editor, not a saved project. Download any text or formatted copy you need before reloading the page or starting over.

Apply Changes puts the editor’s plain text back into the translation panel and updates the main TXT download. Copy also transfers plain text. For a styled version, choose Formatted copy inside Smart edit; it downloads HTML that you can open or print from a browser.

The editor supports up to 100,000 characters, while each AI action uses the smaller limits described above. Save the version you need before reloading or starting over; this is not a resumable editing project.

Translation and Smart edit work on extracted text. Neither recreates the original PDF layout nor writes the translation into the source PDF. To prepare a separate PDF from reviewed text, use Text to PDF.
