How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
TIFF is the format of scanners, print shops and archives. It can hold a picture with no loss at all, sixteen bits per colour, CMYK inks and several pages, and it pays for that in size: tens of megabytes for a single scan are normal. Browsers do not display TIFF, and few websites accept it.
Converting to JPG typically brings a scanned photograph or document down to a small fraction of its size. The page starts at a high quality setting, where a scan shows no visible change at normal viewing. Colours are converted to sRGB, the colour space screens expect, using the profile in the file when it has one, so a CMYK print file does not come out with inverted or dull colours.
A few things are reduced on the way, because JPEG cannot hold them: sixteen-bit files become eight-bit, transparency is filled with white or a colour you choose, and of a TIFF with several pages the first is converted. For line art, text and drawings, PNG is the better target and can be chosen in the editor. Keep the TIFF as your master copy. TIFF files are sent over an encrypted connection, converted on our own servers and deleted within one hour.
TIFF is a container, and what is inside varies
Two TIFF files of the same picture can differ in size tenfold, because the format allows several ways of packing the pixels. Uncompressed is the simplest: an A4 page scanned in colour at 300 dpi is 2480 by 3508 pixels at three bytes each, 26 MB. LZW and ZIP compression are lossless and roughly halve that for a typical scan. A TIFF can even contain JPEG-compressed data, which makes it small and lossy at once. Scanner software usually picks one of these without telling you.
Whatever is inside, the picture is decoded in full and encoded again as a JPG, so the starting compression affects only the size of the upload and not the result.
Black-and-white scans are the exception
There is one kind of TIFF that a JPG conversion makes worse. Office scanners and fax systems save text pages as one-bit images, pure black and pure white, packed with a method designed for exactly that. Such a page is often only 30 to 50 KB. JPEG has no one-bit mode. It has to store the page in shades of grey, the file grows to several hundred kilobytes, and the letters gain a soft halo.
If your TIFF is a text document scanned in black and white, choose PNG in the Format menu instead. PNG keeps the hard black-and-white edges and stays small.
Size limits worth knowing before a big scan
Scans get large fast, and two ceilings apply here. A file may be up to 20 MB without an account and 200 MB with Pro. And a picture may have up to 50 megapixels. A4 at 600 dpi is about 35 megapixels and fits. A3 at 600 dpi is about 70 and does not, so scan an A3 original at 400 dpi or below if it is going to be converted here. For anything that will be viewed on a screen, 300 dpi is already more than enough, and the smaller file uploads in a fraction of the time.
Frequently asked questions
How much smaller will the file be?
It depends on the picture, but a scan saved as uncompressed TIFF usually shrinks to a small fraction of its size.
Does it handle CMYK TIFF files?
Yes. They are converted to sRGB so that they look right on screens.
What about multi-page TIFF files?
The first page is converted.
Is anything lost?
JPEG is lossy and holds eight bits per colour. At the default quality the change is not visible at normal size; keep the TIFF for archiving and printing.
Is there a difference between .tif and .tiff?
None. It is one format with two spellings of the ending, and both are accepted here.
My TIFF has layers from Photoshop. What do I get?
The flattened picture. A layered TIFF stores the merged image as its main picture, and that is what is read. Layers are not kept in a JPG.
