Convert PNG to TIFF

To convert PNG to TIFF, select or drop the PNG on this page and press Convert to TIFF. There are no settings to choose. The TIFF is made in your browser, so the PNG is not uploaded, and it keeps the name: logo.png comes back as logo.tiff.

Both formats store every pixel without loss, so nothing is smoothed or guessed on the way. The route is a single step, graded Exact, and in our tests in Chrome and Firefox a screenshot, a photo and a typed A4 page all came through with every pixel identical. What is a TIFF file explains why printers and archives still ask for the format.

Only the picture itself is copied. Camera details (EXIF), the colour profile and the print resolution stay behind, which matters for print, as the sections below show. Have a photo saved as JPG instead? Convert JPG to TIFF.

A PNG squeezes its pixels without losing any. The TIFF made here is not compressed at all: it stores four bytes for every pixel (red, green, blue and transparency), so its size depends only on the width and height, never on what the picture shows. This PNG to TIFF converter has no compression setting.

Flat colours pack down well in a PNG, so the screenshot grew more than fiftyfold while the photo grew about three times. If nobody has asked you for a TIFF, keep the PNG: JPEG vs PNG helps you choose between those two.

A see-through background stays see-through. The TIFF has a transparency channel (alpha), and in our tests every pixel kept its exact level of transparency, with solid pixels unchanged.

Partly see-through pixels, such as a soft shadow or a glow, keep their colour too. The TIFF labels its transparency the way the PNG stores it (straight, not mixed into the colours), so an image reader that follows the label shows a half see-through shadow in its own colour. In our test a half see-through blue bar read back in the same blue.

• Colour profile: not copied, so the colours are changed to sRGB first. A PNG with no profile, or the usual sRGB one, comes out unchanged, and one saved in a wider colour space (Display P3 or Adobe RGB) keeps its colours as closely as sRGB allows.
• Deep colour: a PNG with 16 bits per colour becomes a TIFF with 8, so 256 shades of each colour instead of 65,536. You will rarely see it, but keep the 16-bit PNG for heavy colour editing.

Need the PNG again later? Convert TIFF to PNG: our screenshot and photo came back with every pixel identical, and the logo’s shadow came back dark blue.

• Print size: the PNG’s resolution is not carried over. Our A4 page saved at 300 DPI came out with its resolution set to 1 and no unit, which a Mac reads as 1 DPI. Every pixel is there, so set 300 DPI, or the print size you want, in the program you print or lay out from.
• Colour: the TIFF is in RGB, like the PNG. This page cannot make a CMYK TIFF.
• An extra channel: every TIFF made here carries a transparency channel, even from a PNG with nothing see-through, such as a screenshot.
