Convert TIFF to PNG — Free Online Converter

TIFF to PNG conversion transforms professional-grade, high-fidelity images into web-ready files that every browser, application, and device can display. TIFF (Tagged Image File Format) is the gold standard for professional photography, print production, medical imaging, and archival storage — but its large file sizes and inconsistent viewer support make it impractical for everyday sharing, web publishing, and cross-platform workflows. PNG bridges this gap by delivering lossless quality in a universally compatible package.

Our converter uses the Sharp library to decode TIFF files — including multi-page TIFFs, 16-bit-per-channel color depths, and various compression schemes (LZW, ZIP, CCITT, uncompressed) — and encode the first page as an optimally compressed PNG. The conversion preserves all visual information within PNG's capabilities: 8-bit or 16-bit channels, full alpha transparency, and embedded color profiles.

TIFF files from professional cameras (Canon, Nikon, Sony), scanners (Epson, Fujitsu, Brother), and design software (Photoshop, Lightroom, Capture One) all convert cleanly. The resulting PNG maintains the original's visual quality while becoming shareable via email, uploadable to websites, and viewable on any device without specialized software.

TIFF files are impractical for sharing and web use. A single uncompressed TIFF from a 24-megapixel camera can exceed 70 MB, while the equivalent PNG typically weighs 15–30 MB and a further-optimized version even less. Email clients reject attachments over 25 MB. Social media platforms do not accept TIFF uploads at all. Web browsers have inconsistent TIFF support — Safari can display some TIFFs, but Chrome, Firefox, and Edge cannot.

Converting to PNG solves these accessibility problems while maintaining lossless quality. Unlike JPG conversion, which introduces lossy compression artifacts, PNG preserves every pixel value from the source TIFF. This makes PNG the right intermediate format for images that may need further editing — you can always convert the PNG to JPG later, but you cannot reverse JPG compression.

PNG's universal compatibility is a decisive advantage. Every web browser, every mobile operating system, every image editor, every email client, and every social media platform handles PNG natively. By converting TIFF to PNG, you make your images accessible to everyone without requiring specialized software like Photoshop, IrfanView, or GIMP.

For web developers and content managers, PNG is the standard lossless web image format. TIFF-to-PNG conversion is a routine step in content pipelines that receive assets from photographers and designers in TIFF format and need to publish them online.

Sharp handles all major TIFF variants: uncompressed, LZW-compressed, ZIP/Deflate-compressed, CCITT Group 3/4 (fax), and JPEG-in-TIFF. Multi-page TIFFs are supported — the converter extracts the first page by default. Color spaces including RGB, CMYK, grayscale, and palette-indexed are decoded and converted to RGB or RGBA for PNG output.

16-bit TIFF images (common in professional photography and scientific imaging) can be output as 16-bit PNG for maximum fidelity or downsampled to 8-bit PNG for broader compatibility. Embedded ICC color profiles (sRGB, Adobe RGB, ProPhoto RGB) are preserved in the PNG's iCCP chunk, ensuring color accuracy across color-managed workflows.

PNG encoding uses compression level 9 with adaptive filtering for optimal file size. Despite being lossless, PNG's DEFLATE compression typically achieves 30–60% size reduction compared to uncompressed TIFF. Compared to LZW-compressed TIFF, PNG files are usually similar in size or slightly smaller.
