Upload one or more TIFF images to combine them into a single downloadable PDF.
Note: for multi-page TIFF files, only the first page of each file is converted.
TIFF is a format commonly produced by document scanners and fax software, valued for lossless image quality, but it isn't natively displayed by web browsers the way JPG or PNG images are — most browsers simply can't open a .tiff file directly. That makes TIFF files awkward to share or preview compared to more web-friendly formats, and converting them to PDF is usually the easiest way to make a scanned TIFF document viewable and shareable everywhere.
This tool uses a dedicated JavaScript TIFF-decoding library to read the pixel data out of your uploaded TIFF files directly in your browser, then places each decoded image onto its own page in a new PDF using a PDF-building library, also running locally. The result is a standard PDF that opens correctly in any PDF viewer, without requiring the recipient to have any special TIFF-compatible software.
It's especially useful for anyone dealing with scanned documents from an office scanner or fax machine (both commonly output TIFF), archivists converting older TIFF-based scans into a more universally viewable format, and professionals in fields like law, healthcare, or government where TIFF remains a common document scanning standard. Because processing happens entirely in your browser, your files are never uploaded to a server.
