TRANSLATE PDF, WORD, EXCEL AND POWERPOINT — AND KEEP THE LAYOUT Most translators hand you back a wall of text. PDF Translator hands you back your document: the same tables, the same columns, the same letterhead and the same page breaks — in a new language. Try it before you pay. No account, no card. KEEPS YOUR FORMATTING - Tables stay tables and columns stay aligned. - Logos, headers, footers and images stay exactly where they were. - Page layout is preserved, so a translated contract still reads like a contract. - Documents that mix several languages can be translated into one single language. EVERY DOCUMENT YOU ACTUALLY WORK WITH - PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx) and photos. - Scanned paperwork: built-in OCR reads the page first, then translates it. - Long documents: split and translated automatically, however many pages. - Up to 133 languages, with automatic language detection. TRANSLATE WITHOUT LEAVING THE APP YOU ARE IN Share a document straight from Mail, Files, Safari or any other app using the built-in extension, and get the translated file back without switching apps. STRAIGHT ANSWERS ON CREDITS - One page costs one credit, and you see the page count before anything is spent. - If a translation fails, the credit goes back into your balance automatically. - No machine-translation watermark on your translated documents. A FULL PDF TOOLKIT AS WELL - Edit the text and images inside a PDF. - Compress a PDF to reduce its file size. - Split, merge and scan, and convert photos into PDF. - Rename, save and share your files, with full Dark Mode support.

PDF Translator's advantage is ratings volume (478 vs 7) and update cadence (monthly vs every 3 months). On price, device support and iOS requirement there is nothing between them.
