How to convert TIFF to PNG
TIFF files are the preferred format for professional photography, print publishing, and archival scanning. They are lossless and can contain high bit-depth image data, ICC color profiles, and even multiple layers. The problem is that TIFF files are rarely supported by web browsers, social media platforms, or standard image sharing tools. Converting to PNG preserves lossless quality in a universally compatible format.
BoltConverter converts TIFF to PNG entirely in your browser using WebAssembly. Your TIFF files never leave your device. Alpha channel transparency and color data are fully preserved in the output PNG.

Frequently asked questions
Is the PNG output lossless?
Yes. TIFF and PNG are both lossless formats. Converting between them involves no quality loss.
Are multi-page TIFF files supported?
Multi-page TIFFs (common for scanned documents) will produce the first page. If you need all pages as separate PNGs, you may need a desktop application.
Does the PNG preserve the alpha channel from the TIFF?
Yes. If the TIFF contains an alpha channel, it is preserved in the PNG output.
Are my files kept private?
Yes. The conversion runs entirely in your browser using WebAssembly. Your TIFF files are never uploaded to any server.
What is the maximum file size supported?
Because conversion runs locally in your browser, there is no server-side size limit. Very large TIFF files may be slow to process depending on your device's available memory.
