JPG to TIFF Converter — Free, Online, No Upload

JPEG works well for sharing photos online, but its lossy compression is a liability in professional workflows. Every time you save a JPEG, it re-compresses and loses a little more detail. For images going into print production, medical imaging systems, or archival storage, TIFF is the expected format because it preserves pixel data exactly.

Desktop publishing applications like Adobe InDesign, QuarkXPress, and professional print workflows default to TIFF for placed images. Photo labs that produce large-format prints often require TIFF files. Scientific journals and academic publishers frequently mandate TIFF at 300 DPI or higher for figures. Geospatial software like ArcGIS and QGIS also uses GeoTIFF (a TIFF variant) as its primary raster format.

One important caveat: converting JPEG to TIFF does not recover detail that JPEG compression already discarded. The TIFF will be losslessly encoded, but the starting point is the already-compressed JPEG data. If the JPEG has visible compression artifacts — blocky shadows, smeared edges — those will be preserved in the TIFF. The benefit is stopping further degradation: no more recompression cycles. File sizes will jump significantly — a 2 MB JPEG may become a 20–30 MB TIFF. That's the cost of lossless storage and print-quality compatibility.

Typical sizes (12MP photo): JPG 2–5 MB → TIFF 20–70 MB.

TIFF will not bring back detail that JPG compression already removed, but it adds no further loss — handy when you need to edit the image.
