Pro Tips
- •TIFF files are uncompressed here, preserving full quality at the cost of larger file sizes than PNG
- •The output includes a proper alpha channel, so transparency from your PNG is preserved
- •Browsers can't preview TIFF files directly, so there's no thumbnail - download the file to view it in an image editor
- •The whole file is converted locally in your browser - nothing is uploaded anywhere

Most users convert print-bound artwork or scans that need TIFF's high fidelity
When to Use This Tool
Convert PNG images to TIFF for professional print workflows that require the format's high fidelity and wide software compatibility.
Export PNG content as TIFF for use in professional photo editing or publishing software that expects high-quality raster input.
Store PNG images as TIFF for long-term archival, since TIFF is a long-established, well-documented format for document and image imaging.
Convert PNG images to uncompressed TIFF before running OCR software, since many OCR tools work natively with TIFF input.
How It Works
Read the uploaded PNG file and decode it using the browser's native image support
Draw the image onto a canvas, preserving its alpha transparency channel
Read the canvas's raw pixel data and manually encode it into the TIFF file format, building the image file directory (IFD) with the required tags
Display the resulting TIFF, ready to download

Frequently Asked Questions
Why can't I see a preview of the TIFF image?
Web browsers don't natively support displaying TIFF images, unlike PNG, JPG, or BMP. The file is still generated correctly - you'll need to open it in an image editor to view it.
Is the TIFF file compressed?
No, this tool produces uncompressed TIFF files for maximum compatibility and to avoid any lossy compression, though this means larger file sizes than compressed formats.
Does the TIFF preserve transparency?
Yes. The output is RGBA with the standard ExtraSamples tag marking the fourth channel as alpha, so transparent areas from your PNG are preserved.
Is my image uploaded to a server?
No. The entire file is read, converted, and encoded locally in your browser. Your image never leaves your device.
Will this TIFF open in Photoshop or other editors?
Yes. The file follows the baseline TIFF 6.0 specification with standard tags, which is supported by virtually all image editing software.
