Why Convert TIFF to PNG?
When you need to convert a TIFF file while preserving every pixel of detail, PNG is the right target. PNG uses lossless compression that keeps your image quality intact while reducing file size compared to uncompressed TIFF. This is ideal for scanned documents, medical images, and professional graphics that need exact pixel reproduction.
PNG also supports transparency, which TIFF may include. Your transparent areas will be preserved in the converted file. PNG works in every browser, every editor, and every operating system — far wider compatibility than TIFF.
LeanImg converts your TIFF files to PNG right in your browser without uploading them anywhere. Your images stay on your device throughout the entire process — completely private, free, and instant.
If file size matters more than pixel-perfect quality, consider TIFF to JPG for much smaller files. After converting to PNG, you can compress your PNG for additional savings while keeping lossless quality.
