AI document translation that keeps your original layout intact
Translated text is redrawn into the original document structure, keeping columns, tables, headings and images in place instead of producing a stripped-down text dump.
Recognises text in scanned PDFs, screenshots, photos, menus and posters, then translates it and puts it back into the image at the same position, size and colour.
Read the source and the translation together, which makes reviewing terminology in contracts and academic papers far faster than flipping between files.
Handles PDF, Word, Excel, PowerPoint and common image formats across 90+ languages, with batch processing for multiple files at once.

Free AI-powered PDF editor, converter and reader for every device
Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact.
Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically.
Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate.
