Open a TIFF online, free
Chrome, Firefox and Edge will not display a TIFF. Upload a TIFF or TIF up to 25 MB and read every page of it in the browser.

Two kinds of TIFF: scans and masters
A scan or a fax is usually bilevel — one bit per pixel, black or white, with no gray in between. Zoomed out, the text looks ragged; at full size it sharpens up. Judge whether a scanned page is legible at full size, not from the thumbnail.
A photographer's or print shop's TIFF is the opposite: 16 bits of color per channel, often CMYK rather than RGB, kept in TIFF precisely because nothing is discarded. Your screen shows 8-bit RGB, so you are seeing a close conversion of a CMYK master, not the ink it will become. Viewing the file changes nothing inside it.
If the rest of what you were sent is DNG, EPS or SVG, the advanced image viewer on this site opens those.
Layers, and where they went
Photoshop writes TIFF layers into a private tag that only Photoshop reads. Every other program shows the flattened composite the file was saved with, and so does this one.
Up to 25 MB
A letter or A4 page scanned at 300 dpi in color, uncompressed, runs to about 25 MB. Compressed with LZW or ZIP it is a fraction of that, so most scans have room to spare.
Zoom to the pixel
Pan across a scan and zoom until individual pixels show — enough to read a stamp, a signature or fine line work.
Nothing is thrown away
TIFF compression is lossless, so re-saving never softens the image the way JPEG does. That is why print shops and archives ask for it.
Deleted after viewing
Your TIFF is removed from the server once you have viewed it. It is not stored, indexed or passed on.
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, so a TIFF you were sent tends to land in your downloads folder and stay there. Upload it here and it renders as pages you can read, up to 25 MB, with nothing installed.
What you are opening is a container rather than a single picture. One TIFF can hold a whole scanned contract, page after page, which is why a document from a scanner or a fax gateway reaches you as one file instead of twenty. The pages are shown in the order they were written into the file.
If another program has already refused your TIFF, the compression is the usual reason rather than damage. 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 usually means, so open the file here before you go looking for a repair tool.
TIFF and TIF are the same format
One specification, two spellings of the extension. Either one opens on this page.
Tagged Image File Format, written out in full.
A container rather than a single image: one file can hold several pages, each with its own compression, color space and bit depth.
The same format shortened to three letters, left over from eight-character filenames.
Nothing inside the file distinguishes it from a TIFF. Renaming between the two changes nothing at all.
Frequently Asked Questions
Didn't find your answer in the FAQ? Contact our sales team
Is it safe to view my TIFF document online?
The upload travels over HTTPS, and your TIFF file is reachable only through a random identifier your browser holds and nothing links to. It is deleted once you have viewed it, which is the part that matters most.
Does Doconut store uploaded TIFF files?
It's important to note that we do not store uploaded TIFF files after processing. It gets deleted as soon as it is viewed. You are requested to avoid uploading invalid format, corrupt or infected documents here.
Are there any limits to using Doconut.app to view TIFF files?
One TIFF file at a time, up to 25MB. That ceiling is set per format, so another viewer here may take more or less than this page does.
