TIFF to JPEG Converter

Q: What if the form also caps the JPEG at 500 KB?

Convert first, then check the size. Run the JPEG through [compress JPEG to 500 KB](/compress-jpeg-to-500kb), which lowers quality and, if needed, dimensions until the file fits.

Change a TIFF from a fax server, document scanner or print workflow into a JPEG that an upload form, a case-management portal or a phone will accept. Each page of a multi-page TIFF comes back as its own JPEG.

How to use this tool

1
Upload the TIFF files
Add up to 20 .tiff or .tif files of up to 95 MB each.
2
Choose gray for text pages
For faxes and black-and-white scans, set Color space to Grayscale under Advanced settings.
3
Convert to JPEG
Press Convert to JPG; the files are standard JPEG. Rename the extension to .jpeg if a form insists on that spelling.

TIFF is how fax servers and scanners store pages; JPEG is what upload forms accept. Converting takes one click, and for text pages Grayscale keeps the result small.

Convert TIFF to JPEG when a form or program wants the .jpeg spelling

TIFF was created by Aldus in 1986 for desktop scanners, and its specification is now held by Adobe. JPEG was standardized in 1992 by the Joint Photographic Experts Group. The long spellings, .tiff and .jpeg, are the names the formats were given; .tif and .jpg exist only because MS-DOS limited file extensions to three characters. Software with Mac or Unix roots, including macOS Preview and many document management systems, writes the long forms.

That matters in one practical case: validators that compare the extension as text. Most check the content of the file and accept either spelling, but a few older case-management and e-filing portals keep an allow-list with just ".jpeg" or just ".jpg". The converter writes a standard JPEG; if the form rejects the name, renaming the extension is safe, because the bytes are identical.

Fax TIFF resolutions and the JPEG page size you get

Size	Pixels	cm	in	DPI	Fits
Std	1728 × 1143	21.5 × 29.7	8.5 × 11.7	204 × 98	Standard fax mode; pixels about twice as tall as wide
Fine	1728 × 2287	21.5 × 29.7	8.5 × 11.7	204 × 196	Fine fax mode; near-square pixels, converts cleanly
S-fine	1728 × 4572	21.5 × 29.7	8.5 × 11.7	204 × 391	Superfine; sharp text, larger JPEG
300	2550 × 3300	21.6 × 27.9	8.5 × 11	300	US Letter from a typical document-feeder scanner

TIFF

Tagged Image File Format

TIFF was created by Aldus in 1986 and is now maintained by Adobe. It is a flexible container that can store images uncompressed, with lossless LZW or ZIP compression, or with lossy JPEG compression, and it supports layers, multiple pages, high bit depths and transparency. Printers, publishers, scanners and archives rely on it because it preserves full quality and colour information. The downside is very large files and inconsistent support for some of its options between programs. Browsers do not display TIFF, but most image editors and operating system viewers do.

Compression: Lossy or lossless
Transparency: Yes
Animation: No

JPG

JPEG image

JPEG (or JPG) is the most widely used photo format, standardised by the Joint Photographic Experts Group in 1992. It uses lossy compression that discards fine detail the eye is unlikely to notice, which keeps photos small enough for the web, email and phone storage. It handles smooth gradients and natural scenes well, but sharp text, line art and flat colours pick up visible blocky or fuzzy artefacts. JPEG has no transparency and no animation, and every re-save loses a little more quality. Every browser, phone, camera and image editor can open it.

TIFF to JPEG is requested by people holding fax pages or scanner output in the full-length TIFF spelling who must submit to a portal or document system that names JPEG; the opposite trip, JPEG to TIFF, only happens when a printer or archive demands TIFF.

Group 4 and other fax TIFFs: what changes in the JPEG

Fax software stores pages as TIFF Class F, a profile of TIFF that uses the ITU-T fax codecs: Group 3 (T.4, 1980) or the more efficient Group 4 (T.6, 1984). Both encode a page as runs of pure black and pure white. JPEG has no notion of a 1-bit page, so letters gain a thin gray edge and the file grows.

Scanner TIFFs are different. A color scan saved with LZW compression or no compression at all is often tens of megabytes,, and the JPEG is a small fraction of that. For a multi-page contract that will be read rather than viewed as pictures, a PDF is often the better container; how to scan documents to PDF covers that route.

Before you upload the JPEG

Open one page and check that it is not squashed to half height
Use Grayscale for fax and text pages
Rename to .jpeg only if the form rejects .jpg
Compare the file size with the form's limit
Keep the original TIFF; faxes are often evidence

TIFF to JPEG questions for fax and form users

Why do some programs save .tiff and .jpeg while others save .tif and .jpg?

The three-letter spellings come from MS-DOS and early Windows, which allowed only three characters after the dot. Mac and Unix software had no such limit and used the full names, and macOS Preview still exports .jpeg by default.

Why is a tiny Group 4 fax TIFF a much bigger JPEG?

CCITT Group 4 stores a 1-bit page as runs of black and white and can squeeze a text page into a few dozen kilobytes. JPEG has no 1-bit mode, so the page becomes 8-bit grayscale and JPEG's blocks spend bytes on every letter edge. A page several times larger than the TIFF is normal.

Should I pick Grayscale for a faxed or scanned text page?

Yes. A fax has no color to keep, and a grayscale JPEG stores one channel instead of three, so it is smaller and loads faster in a portal's preview. Keep sRGB for photos, color charts and anything with a stamp or highlighter mark that matters.

Why does my faxed page look squashed after conversion?

Standard-mode faxes are scanned at 204 × 98 dpi, so each pixel is about twice as tall as it is wide. Viewers that ignore the TIFF's separate horizontal and vertical resolution show the page at roughly half its height. If the JPEG looks flattened, ask the sender to resend in fine mode, which is close to square.

What happens to the transparent areas of a TIFF cut-out?

JPEG has no transparency, so transparent pixels are filled with white, or with black or a custom color chosen under Transparent areas. Choose TIFF to PNG if the cut-out has to stay transparent.

What if the form also caps the JPEG at 500 KB?

Convert first, then check the size. Run the JPEG through compress JPEG to 500 KB, which lowers quality and, if needed, dimensions until the file fits.
