PNG is a lossless format that is widely supported across all platforms and applications. Converting a TIFF to PNG reduces file size while maintaining pixel-perfect quality — no image data is lost. PNG is also much more widely supported than TIFF, making it the right format for sharing, web use, and cross-platform workflows. Dockitt uses the tiff library to decode the image entirely in your browser.

How to use

  1. Click 'Choose TIFF' and select the TIFF image you want to convert.
  2. Click 'Convert to PNG' and wait while the image is decoded and processed.
  3. Download the PNG file.

FAQ

Is there any quality loss converting TIFF to PNG?

No. PNG is lossless — every pixel from the source TIFF is preserved exactly in the output PNG. This makes TIFF-to-PNG a safe, lossless conversion.

Will the PNG be smaller than the TIFF?

It depends on the TIFF compression. Uncompressed TIFFs will produce significantly smaller PNGs. LZW-compressed TIFFs may produce PNGs of similar size. For photographic content, PNG files are generally much smaller than uncompressed TIFF.

What TIFF formats are supported?

This tool supports grayscale (1-channel), RGB (3-channel), and RGBA (4-channel) TIFF images at 8-bit and 16-bit per channel. The first page of multi-page TIFFs is converted.

Is the conversion done in my browser or on a server?

The conversion runs entirely in your browser using the tiff JavaScript library and the Canvas API. Your image is never uploaded to any server.
