JFIF to TIFF, explained
Convert JFIF to TIFF directly on your device. Create a single-image TIFF raster copy for a TIFF-compatible application. Check the decoded photo before conversion. A .jfif extension does not guarantee valid JPEG data, and damaged downloads can still fail.
Choose JFIF files and confirm the preview.
Keep TIFF selected. Review the output behavior below before converting.
Convert and download the TIFF results. Multiple results can be saved together as a ZIP.
Reading your JFIF source
A .jfif download commonly contains JPEG image data. This tool decodes and re-encodes that image; it does more than rename the extension. Existing compression artifacts remain and source metadata is removed.
Settings for TIFF output
TIFF export writes the decoded 8-bit RGBA raster without a quality slider. Decoded alpha can be retained. It does not offer CMYK, print-profile or high-bit-depth export controls.
Dimensions in JFIF to TIFF
Original size keeps decoded raster dimensions. Advanced Settings offers percentage scaling or fit within a maximum width and height, with aspect ratio preserved and no cropping. Input and output safety limits both apply.
What survives the conversion
The TIFF is a raster copy, not a restored archival master. Each result contains one image; multiple outputs are delivered separately or as a ZIP, not merged into a multipage TIFF. Check the decoded photo before conversion. A .jfif extension does not guarantee valid JPEG data, and damaged downloads can still fail.
Batch processing and device limits
Choose up to 50 files, each at most 64 MB. Decoded images must fit 24 megapixels and 16,384 pixels per side; total outputs are capped at 256 MB. All conversion runs on this device. Source metadata is removed, and damaged or unsupported variants can fail without changing the originals.
