Supports: JPG, JPEG, JFIF
A .jfif file is an ordinary JPEG that Windows happened to save with an unfamiliar extension, so this is really a "JPEG to TIFF" conversion: it takes a lossy JPEG image and rewraps its pixels inside TIFF, the lossless raster container built for print, scanning, and archival masters rather than for the web. The reference tables below explain exactly what each format is and what changes when you cross from one to the other. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.

.jfif onto the page or click "+ Add Files" to browse. The uploader also accepts .jpg and .jpeg, and you can queue several images at once.No. JFIF and JPG are the same image format — JFIF (JPEG File Interchange Format, led by Eric Hamilton at C-Cube Microsystems in late 1991 and later formalized as ITU-T T.871) only defines how a JPEG is wrapped, and the bytes inside a .jfif are an ordinary JPEG bitstream under the image/jpeg MIME type. Windows began saving some pasted and downloaded images with the .jfif extension after a change to its JPEG file association, which is why a few apps that balk at .jfif open the identical file fine once it is renamed .jpg. The TIFF you get is the same whether you upload .jfif, .jpg, or .jpeg. If all you wanted was to fix the extension, JFIF to JPG renames it without re-encoding.
No, and no converter can. TIFF is lossless, but it can only preserve the pixels it is handed — it cannot rebuild detail the original JPEG already discarded through lossy compression. Converting JFIF to TIFF gives you a re-editable, lossless master at a much larger file size, which is useful before heavy editing or a print hand-off, but the picture itself will not look sharper than the JFIF you started with. The conversion adds no new loss; it simply stops discarding more.
Both, and on this converter you choose. The lossless options — None, LZW, Deflate (ZIP), and PackBits — keep every pixel intact and differ only in file size and speed; LZW has long been treated as the de-facto standard for TIFF and offers the broadest software compatibility. The format also defines a lossy JPEG-in-TIFF mode. Since your source is already a lossy JFIF, a lossless Compression Type is usually the right pick for an archival or print master.
Considerably larger — often several times the size. JPEG's lossy compression is what made your .jfif small in the first place; a lossless TIFF stores the decoded pixels without that aggressive size reduction, so even a Deflate- or LZW-compressed TIFF will dwarf the original. The exact ratio depends on the image and the Compression Type you choose (None is largest, LZW and Deflate are smaller but still lossless). If you actually need a small file for sharing or the web, TIFF is the wrong target — keep it as JPEG or use JFIF to PNG for a lossless format that browsers display.
Your JFIF is an 8-bit-per-channel image, and the conversion preserves that — it does not invent extra tonal precision the JPEG never carried. TIFF as a format supports up to 16 bits per channel, which matters when the source is a high-bit-depth scan or RAW render, but converting an 8-bit JFIF gives you an 8-bit TIFF. The benefit here is the lossless, widely-supported container, not a deeper bit depth.
Yes — .tif and .tiff are two spellings of the same Tagged Image File Format, and the bytes inside are identical. The three-letter .tif dates back to MS-DOS and early Windows, which capped extensions at three characters under the 8.3 filename rule. Use the TIFF / TIF toggle to match whatever your other software expects; either produces the same file. If your workflow specifically wants the short extension, JFIF to TIF is this exact conversion labeled that way.
TIFF is what print shops, scanners, and desktop-publishing tools expect, and it carries CMYK color that PNG does not — so it is the right pick for a print pipeline or an editing hand-off. PNG is the better lossless choice when the image needs to display in a browser, since per MDN only Safari renders TIFF natively and TIFF is not used for web content. If your copy is headed for the screen rather than a press, JFIF to PNG is usually the more practical lossless format.
Your file is uploaded over an encrypted connection, converted to TIFF on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. The main practical limit is upload size and time, not your device.
