About Image to PDF Converter: what you should know

Office workers, students, and legal professionals handling PDF documents daily. From combining contracts and reports to preparing application packets, this PDF tool processes files locally in your browser — no upload to an external server, no waiting in a queue.

Key features

  • Zero Server Upload — All PDF processing runs locally in your browser using pdf-lib and pdf.js. Confidential contracts and personal documents never touch an external server.
  • Multi-File Support — Upload one or several PDF files and process them together. Drag to reorder if needed — the tool handles batches without choking on large documents.
  • Visual Page Preview — See thumbnail previews of your pages before confirming the action. This prevents mistakes when selecting page ranges or reordering documents.

Common use cases

  • Combining Scans into One File — A multi-page document scanned as separate images needs to become one PDF. Merge them in order so the recipient sees a complete file.
