Browsers do not render TIFF. Safari is the only exception, because macOS decodes the format for every app on the system.
Windows Photos opens a multi-page TIFF and shows the first page only, with no indication that there are others. Use Windows Photo Viewer, or convert the file to PDF and the pages become pages.
A TIFF arrives from a scanner, a fax gateway or a records office, and the machine treats it as something exotic. Double-clicking produces an app you have never opened, a grey window, or a single page out of a document you know runs to forty.
Why the browser refuses
Drag a TIFF into Chrome and it downloads rather than displays. Firefox and Edge behave the same way. None of them ship a TIFF decoder and none of them intend to. The format never became a web format, and the ones that did cover everything a page needs.
Safari is the exception, and it is an exception by accident rather than by decision. macOS decodes TIFF at the system level, through the same imaging framework that Preview and Quick Look use, so Safari inherits the support without doing anything. iOS works the same way.
That asymmetry explains a situation people run into constantly. Someone on a Mac opens the link, watches the file render in their browser, and reports that it works fine. On Windows it has never worked for anyone, and both parties are telling the truth.
What opens a TIFF, platform by platform
- Windows PhotosOpens it. First page only
- Windows Photo ViewerAll pages, arrow keys to move
- Windows PaintFirst page, and offers to flatten it
- macOS PreviewAll pages, thumbnails in the sidebar
- iPhone, Files or PhotosAll pages, swipe between them
- Android, out of the boxNo built-in handler at all
- GIMP, IrfanView, XnViewAll pages, free, any platform
Windows Photo Viewer is still present in Windows 11, just no longer wired to anything. Right-click the file, choose Open with, then Choose another app, and it appears in the list on most machines that were upgraded rather than clean-installed. On a clean install it needs a registry change to show up, which is more effort than the file is worth.
The trap: page one, and no sign of the rest
TIFF was designed as a container rather than a picture. A file holds a chain of image directories, each one a complete image with its own dimensions, colour depth and compression, each pointing at the offset of the next. A forty page fax is forty entries in that chain inside one file.
Most viewers read the first entry and stop. They are not broken and they do not warn you, because as far as the format is concerned a file with one image in it is entirely valid. Microsoft Q&A carries the same answer for the Photos app: it shows the first page and offers no way to reach the others.
File size is the quickest way to catch it. A black and white page scanned at 300 dpi with Group 4 compression lands somewhere between 30 and 80 KB. If a file you believe is one page weighs 6 MB, it is not one page. On Windows, Properties then Details will sometimes report the page count outright. On a Mac, Preview shows every page in the sidebar without being asked.
The compression decides whether anything can open it
TIFF permits several compression schemes and no decoder implements all of them. That is the other reason the same file opens on one machine and fails on the next.
- CCITT Group 4Bitonal fax and document scans. Tiny, and read everywhere
- LZWGeneral purpose, lossless, effectively universal
- DeflateBetter ratios than LZW, slightly less widely handled
- JPEG, scheme 7Photographic pages inside a TIFF. Broadly supported
- Old-style JPEG, scheme 6Deprecated in the 1990s. Still emitted by some scanners, read by almost nothing
- JPEG 2000 and vendor codecsSpecialist imaging equipment. Not readable outside it
If a file refuses to open in everything, including Preview on a Mac, old-style JPEG or a proprietary codec is the likely explanation. The TIFF 6.0 specification deprecated the former more than thirty years ago and scanners still produce it. There is no fix at your end. Go back to whatever wrote the file and ask for it in a scheme from the top of that list.
The answer that works on every machine
Converting to PDF settles both problems in one pass. Every directory in the chain becomes a page in the document, the page count is visible in every reader, and the result opens in a browser, on a phone, in an email client and on the machine of whoever you send it to.
The thing a converter has to get right is the resolution tag. A TIFF records the number of pixels per inch it was scanned at, and that number is what decides the paper size at the other end. An image of 2550 by 3300 pixels at 300 dpi is US Letter. The same pixels at 96 dpi is close to a poster, which is how a perfectly ordinary scan ends up as a PDF nobody can print.
Fax is the awkward case, because fax pixels are not square. ITU-T T.4 sends 204 pixels per inch across the page and 98 down it, or 196 down in fine mode. A converter that assumes square pixels squashes the page to roughly half its height. That is the difference between a converted fax that merely looks rough, which is the format's fault, and one that looks compressed, which is the converter's.
Turn a multi-page TIFF into a multi-page PDF
Every page in the file becomes a page in the document, at the size the scanner recorded. Nothing is uploaded.
Common questions
Pages, platforms and the files that refuse to open anywhere.
01Why will my TIFF not open in Chrome?
Chrome ships no TIFF decoder, and neither do Firefox or Edge. Safari is the exception because macOS decodes the format for every application on the system, so it gets the support for free.
02How do I see all the pages of a multi-page TIFF on Windows?
Right-click the file, choose Open with, and pick Windows Photo Viewer, which pages through the whole chain. The modern Photos app shows the first page and gives no way to reach the rest.
03Is .tif different from .tiff?
Same format, two extensions, left over from the days when extensions were limited to three characters. Nothing treats them differently.
04Why is my TIFF so large?
Either it is uncompressed, or it holds far more pages than your viewer is showing. A bitonal page at 300 dpi compresses to well under 100 KB with Group 4, so anything in the megabytes is carrying colour, high resolution or a stack of pages.
05Why does a converted fax look stretched?
Fax pixels are not square. The standard sends 204 across and 98 down, so a converter that assumes square pixels halves the page height. The fix is on the converter's side, not yours.
06Can I open a TIFF on a phone?
An iPhone opens one through Quick Look in Files or Photos and swipes between the pages. Android has no reliable built-in handler, so converting to PDF first is the shorter route.
