The archive-to-inbox conversion
TIFF to PDF traffic comes overwhelmingly from paperwork: a scanner or office copier produced TIFF files years ago, and today an insurer, court, bank or government portal wants those same pages as PDF. The documents involved, medical records, deeds, old contracts, are usually the most sensitive files a person owns, which makes the upload-to-a-server model of most converters a poor fit. Here the TIFF is decoded by UTIF.js, a pure JavaScript TIFF reader, inside your own browser.
Smaller files, same page
Uncompressed or LZW TIFF scans are famously bulky; a single letter-size 300 dpi scan often weighs 20 MB or more. Re-wrapped as a PDF with high-quality JPEG compression, the same page typically lands under 1 MB, small enough to email or upload anywhere, with no visible difference on a document. Need just the image rather than a document? TIFF to JPG and TIFF to PNG extract it directly.
Common questions
Why do scanners produce TIFF and offices demand PDF?+−
TIFF became the scanning standard in the 1990s because it stores pages losslessly and supports fax compression. Modern document systems standardized on PDF instead. The content is the same scanned page; only the wrapper is outdated, which is exactly what this conversion fixes.
What about multi-page TIFF files?+−
Currently the first page is converted; multi-page TIFF support is on our roadmap. Most single-scan files contain one page, but if your fax archive relies on multi-page TIFFs, tell us and we will prioritize it.
Will the scan quality survive?+−
Yes. The TIFF is decoded exactly, then embedded at high JPEG quality on a page matching the scan's own dimensions. For typical 200 to 300 dpi document scans the result is visually identical and dramatically smaller than the source TIFF.
Is this safe for sensitive scanned documents?+−
Safer than any upload-based tool: scans of contracts, medical records and IDs are exactly why this site converts locally. The file is read and processed inside your browser's memory. You can disconnect from the internet after loading the page and it still works.
