How to Convert TIFF to PNG While Preserving Quality
TIFF is the professional standard for lossless image storage, but it is poorly supported outside of specialized software. Web browsers do not display TIFF files, most email clients cannot preview them, and many applications refuse to import them. PNG offers a universally compatible lossless alternative that preserves every pixel from the TIFF source.
If you need to share a high-quality image without any lossy compression, TIFF to PNG conversion is the right path. The output files are smaller than raw TIFF while maintaining full fidelity.
Step-by-Step Instructions
- Open the TIFF to PNG converter
Go to imageconvert.co/tiff-to-png in your web browser. Works on any device without installation or account creation.
- Add your TIFF files
Drag and drop one or more TIFF images onto the page, or click to browse your file system. Batch conversion is fully supported.
- Download the PNG output
PNG is always lossless, so there is no quality setting to adjust. Each TIFF is decoded and re-encoded as PNG locally in your browser. Download individually or as a ZIP.
Why Convert TIFF to PNG Instead of JPG
Both PNG and JPG are valid targets for TIFF conversion, but they serve different purposes. JPG applies lossy compression, which reduces file sizes dramatically but discards some image data. PNG uses lossless compression, preserving every pixel from the decoded TIFF at the cost of larger files.
Choose PNG when you need to preserve quality for further editing, when the image contains transparency (some TIFF files have alpha channels), or when the image has sharp text and line art that JPG compression would damage. Choose JPG when file size is the priority and the image is photographic content where lossy compression is visually undetectable.
File Size Comparison: TIFF vs PNG
PNG files are generally smaller than uncompressed TIFF files because PNG uses DEFLATE lossless compression. A 50 MB uncompressed TIFF might produce a 15-25 MB PNG depending on image complexity. If the TIFF already uses LZW compression, the PNG will be roughly similar in size since both are lossless compression schemes.
The key advantage of PNG is not file size reduction but compatibility. PNG opens in every browser, every image editor, every office application, and every operating system. TIFF is supported mainly by professional software.
Preserving Color Depth and Quality
TIFF files from professional cameras and scanners often use 16-bit color depth per channel. Standard PNG supports up to 16 bits per channel as well, so the full color depth of the TIFF can be preserved during conversion. This makes PNG suitable for professional workflows where color accuracy matters.
By contrast, JPG is limited to 8 bits per channel. Converting a 16-bit TIFF to JPG reduces the color depth, potentially losing subtle tonal gradations. For color-critical work, TIFF to PNG is the safer conversion path.
Handling Scanned Documents
Scanners frequently output TIFF files, especially in office and archival environments. Converting scanned documents to PNG maintains the full quality of the scan while producing files that can be easily shared, emailed, and inserted into documents. For text-heavy scanned documents, PNG is strongly preferred over JPG because lossy compression creates visible artifacts around text characters.
Frequently Asked Questions
Is TIFF to PNG conversion lossless?
Yes. Both TIFF and PNG support lossless compression. The conversion decodes the TIFF pixel data and re-encodes it as PNG without any quality loss.
Why are PNG files still large after converting from TIFF?
PNG uses lossless compression, so photographic content remains large. If you need dramatically smaller files, convert to JPG instead and accept the minor lossy quality trade-off.
Does the conversion preserve TIFF metadata?
Basic image data (pixels, dimensions, color depth) is preserved. TIFF-specific metadata like EXIF data, ICC color profiles, and custom tags may not carry over to the PNG format.
Can I convert multi-page TIFF files to PNG?
The converter processes the first page of multi-page TIFF files. For documents with multiple pages, split the TIFF into individual files first, then batch convert to PNG.
