Master Converter

Master Converter is an online PDF converter that puts common PDF tasks—conversion, optimization, editing, security, and “intelligence” like OCR and data extraction—into one browser-based workflow. Convert between PDFs and formats such as Word (DOCX), Excel (XLSX), PowerPoint (PPTX), EPUB, HTML, and images (JPG/PNG/HEIC/WebP), plus render a web page to PDF using a URL.

Beyond conversion, you can optimize and repair PDFs, then transform them for distribution and archiving. Features include compressing to reduce file size, repairing corrupted PDFs, splitting or merging documents, rotating pages, flattening form fields and annotations, and adding page numbers or text watermarks. You can also convert PDFs to PDF/A for long-term archiving.

For document protection and verification, Master Converter supports encrypting and decrypting PDFs, signing PDFs with an image signature, and comparing results via its security tools. If you need the content to be readable and searchable, OCR recognizes text in PDFs and makes scans searchable.

The platform runs entirely in your browser on desktop or mobile, with encrypted uploads over HTTPS. There’s no subscription; you pay as you go using one-time credit packs—most PDF jobs cost 2 credits, OCR costs 5 credits, and your credits stay valid while your account is active. Files are auto-deleted after processing.

Do I need to install any software to use Master Converter?

No—everything runs in your browser, so there’s no install or plugin required.
