A TIFF does not open in a browser by itself. Chrome, Firefox and Edge have never rendered the format, and Safari is the only common exception, which is why a TIFF you were sent tends to land in your downloads folder and stay there.

Upload it to the TIFF viewer — .tiff and .tif, up to 25 MB — and it renders as pages you can read, with nothing installed and no account. The file is deleted when you close the tab.

Why Choose Doconut.app for TIFF Files?

It is a container, not a picture. One TIFF can hold a whole scanned contract, page after page, which is why a document from a scanner or a fax gateway arrives as one file instead of twenty. The pages render in the order they were written into the file.
The compression is usually why another program refused it. LZW, ZIP, PackBits, CCITT Group 4 and JPEG inside a TIFF are all legal in the same format, and a reader that handles one may not handle the next. That is what a "damaged file" message about a TIFF normally means — so try opening it here before you go looking for a repair tool.
No installation, no account, and the file deleted afterwards.
Up to 25 MB. For scale: an A4 page scanned at 300 dpi in colour and left uncompressed runs to roughly that on its own. Compressed with LZW it is a fraction of it, so most real scans have room to spare.

Industries That Benefit from TIFF Viewing

Legal and administrative: multi-page scans of contracts, filings and correspondence — the most common reason a TIFF reaches anybody.
Engineering and construction: scanned schematics and record drawings.
Publishing and graphic design: TIFF compression is lossless, so re-saving never softens an image the way JPEG does, which is why print shops and archives ask for it.
Healthcare: scanned reports and exported stills, but not DICOM — .dcm and .ima are deliberately excluded from the free viewers, because a DICOM file carries patient identifiers alongside the image.

Upgrade Your Workflow with Doconut .NET Library

If it needs to happen inside your own software

That is a different product rather than an upgrade path: the Doconut SDK, a licensed .NET component installed in your environment, rendering on your servers with no calls back to us. It covers the same TIFF handling plus 75 extensions in total.

For one file today, open the TIFF viewer and drop it in. If your image turns out to be an EPS, a CDR or a camera raw instead, the vector and raw image viewer takes those.
