Are my images uploaded to a server?

No. The entire conversion runs inside your browser using the HTML5 Canvas API. Your image file never leaves your device.

Why would I use TIFF instead of PNG?

TIFF is the preferred format for professional print workflows, prepress, and archival imaging. Many professional applications, scanners, and print services require or strongly prefer TIFF. Both PNG and TIFF are lossless, but TIFF has broader support in professional and legacy imaging software.

What color depth does the output use?

The output uses 24-bit RGB (8 bits per channel). Transparency from the PNG is composited onto the background color you choose before conversion, since this tool produces an RGB TIFF without an alpha channel.

Does TIFF support transparency?

The TIFF format supports an alpha channel, but this tool outputs a standard 24-bit RGB TIFF for maximum compatibility. Any transparent pixels in your PNG are composited onto the background color you select.

Is there a file size limit?

The limit is your browser's available memory. Very large images may be slow to process on low-end devices. Images under 4000 × 4000 pixels work reliably in all modern browsers.

Which browsers are supported?

All modern browsers — Chrome, Edge, Firefox, and Safari 14+. The Canvas API, Blob downloads, and Uint8Array typed arrays used for TIFF encoding are universally supported.

Summary

This tool converts PNG images to TIFF (Tagged Image File Format) entirely inside your browser using the HTML5 Canvas API. No files are ever uploaded to a server — all processing happens locally on your device. TIFF is a lossless, flexible raster format widely used in professional photography, print prepress, document scanning, and medical imaging. The output is a baseline TIFF with 24-bit RGB color, compatible with Photoshop, GIMP, macOS Preview, Windows Photo Viewer, and virtually every professional imaging application.
