🖼️ TIFF to PNG: Preserve Every Pixel & Transparency Channel

TIFF (Tagged Image File Format) is the gold standard for professional imaging — used in scanning, printing, medical imaging, and high-end photography. However, TIFF files are often too large for web sharing or incompatible with many online platforms. Converting TIFF to PNG gives you lossless quality, full alpha transparency, and universal compatibility across all devices and browsers.

✨ Key Benefits of TIFF to PNG Conversion

• Complete Transparency Support: Preserves alpha channels from TIFF images (e.g., layered graphics, logos).
• Lossless Compression: Zero quality degradation — ideal for archiving scanned photos, documents, and medical images.
• Universal Compatibility: PNG works on Windows, Mac, Linux, iOS, Android, and all web browsers without plugins.
• 100% Client-Side Security: Your TIFF files never leave your device — no uploads, no servers, complete privacy.
• Free & Unlimited: Convert as many TIFF/TIF images as you need without registration or watermarks.

🔄 How Our TIFF to PNG Converter Works

We use Tiff.js (a port of LibTIFF) to parse and decode TIFF files entirely within your browser. When you select a TIFF file, the tool reads all image directories (IFDs), extracts pixel data, color profiles, and alpha transparency, then renders the image on a hidden canvas. The canvas is then exported as a PNG blob with native lossless compression — all locally, no server involved.

❓ Frequently Asked Questions

Q: Does this tool preserve transparency from TIFF?
A: Yes! If your TIFF includes an alpha channel (e.g., from Photoshop or GIMP), it is fully preserved in the output PNG.

Q: Is my image uploaded to any server?
A: Absolutely not. Tiff.js runs client-side. Your files stay on your device — 100% private.

Q: What TIFF compressions are supported?
A: Uncompressed, LZW, PackBits, Deflate (ZIP), and CCITT G3/G4 for bi-level images are supported through Tiff.js.

Q: Will I lose quality converting to PNG?
A: No — PNG uses lossless compression. The output will be visually identical to the original TIFF data.

Q: Can I convert multi-page TIFFs?
A: Currently the tool converts the first page of multi-page TIFFs. For multi-document conversion, repeat for each page.
