TIFF (Tagged Image File Format) is the workhorse of professional scanning, medical imaging, and document archival. It preserves every pixel losslessly — perfect for X-rays, blueprints, and legal evidence — but most consumer apps and email clients can't open it. Even when they do, multi-page TIFFs (common output from book scanners and fax machines) often render as just the first page. PDF preserves multi-page documents natively and opens everywhere.
PDFly decodes the TIFF in your browser using a pure-JavaScript decoder (utif), then embeds the resulting raster into a PDF page. Multi-page TIFFs become multi-page PDFs. The original TIFF and the resulting PDF never leave your device.
