เกี่ยวกับการแปลง TIFF เป็น PNG
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.
ทำไมต้องแปลง TIFF เป็น PNG
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.
