MoyuYa: AI-Driven Next-Gen Lightweight PDF Toolkit 85

摸鱼鸭 (MoYuYa) is an online PDF processing tool that handles a wide range of PDF-related tasks. It supports converting PDFs to and from formats such as Word, PPT, Excel, and images. It also lets you merge, split, compress, add or remove pages, apply watermarks, reorder pages, rotate pages, and add page numbers to PDFs. To address the challenges of scanned PDF conversion and text recognition, the team added OCR (Optical Character Recognition) capabilities, enabling features like image-to-Word and image-to-Excel conversion.

Main Features of 摸鱼鸭

• Format Conversion: PDFs can be converted to and from Word, PPT, Excel, and images. For example, PDF-to-Word preserves the original layout, PDF-to-Excel accurately recognizes tabular data, PDF-to-PPT produces slides, and PDF-to-image produces high-resolution images. Additionally, Word, Excel, and PPT files can also be converted to PDF.

• Document Organization: You can merge, split, and compress PDFs. Multiple PDFs can be combined into one, or split by page range or single pages. Compression uses intelligent methods that reduce file size while largely preserving quality.

• Editing & Processing: You can reorder pages, rotate pages, add or remove pages, insert pages, change page orientation, add page numbers, extract pages, and perform simple editing operations such as splitting, merging, deleting pages, and switching pages.

• Security & Protection: You can add watermarks to PDFs, encrypt and decrypt files, and add watermarks to images. It uses reliable security technology to encrypt files, apply watermarks for protection, and unlock permissions so files can be edited.

• OCR Text Recognition: It can convert scanned PDFs to Word, extract tables, and convert images to Word or Excel. The proprietary OCR algorithm recognizes both printed text and common handwriting, and can automatically detect table borders to generate editable Excel files. As of May 2025, it supports recognition of multiple languages including Chinese, English, and Japanese.
