TIFF and PNG are both lossless image formats — they compress image data without discarding any information. A TIFF and PNG derived from the same original image will look identical on screen at the same bit depth. The differences are in what each format can contain, where it can be used, and what professional workflows expect.
PNG (Portable Network Graphics, 1996) was designed as a web-safe, patent-free replacement for GIF. It handles transparency, supports up to 16-bit color depth, and uses DEFLATE compression. It's the dominant lossless format for web graphics, UI design, and screenshots.
TIFF (Tagged Image File Format, 1986) was designed for professional print and photography. It supports multiple subfiles in a single file (multi-page TIFFs), 8/16/32-bit color, floating-point data, LAB and CMYK color spaces, multiple compression algorithms (LZW, ZIP, JPEG, uncompressed), and a rich metadata structure that Photoshop and Lightroom use to store layer data. These features make TIFF the standard for scanner output, professional photography archives, and commercial printing.
Technical Comparison: TIFF vs PNG
| Feature | TIFF | PNG |
|---|---|---|
| Color modes | RGB, CMYK, LAB, Grayscale, Indexed, Bitmap | RGB, Grayscale, Indexed |
| Max bit depth | 32-bit per channel (128-bit total) | 16-bit per channel (48-bit total) |
| Transparency | Alpha channel support | Full 8-bit alpha (256 levels) |
| Layers | Yes (Adobe TIFF extension) | No |
| Multi-page | Yes (multiple images in one file) | No (APNG for animation only) |
| Compression options | None, LZW, ZIP, JPEG, PackBits, CCITT | DEFLATE only (level 0-9) |
| CMYK support | Yes (essential for print) | No |
| Embedded ICC profiles | Yes | Yes |
| EXIF metadata | Yes (full) | Limited (basic metadata in chunks) |
| IPTC / XMP metadata | Yes (full) | Limited |
| Web browser support | Very limited (no native browser support) | Full (universal browser support) |
| File size (typical) | Larger (less efficient compression) | Smaller (better DEFLATE compression) |
File Size Comparison
Both formats are lossless, but their compression approaches differ. PNG generally achieves better compression for images with large flat-color areas. TIFF with LZW or ZIP compression is comparable, but uncompressed TIFF files are dramatically larger. Your mileage will vary significantly based on image content.
| Image Type | Dimensions | TIFF (LZW) | TIFF (uncompressed) | PNG |
|---|---|---|---|---|
| 12MP photograph | 4000×3000 | ~18–25 MB | ~34 MB | ~16–22 MB |
| Screenshot (UI) | 1920×1080 | ~2–4 MB | ~6 MB | ~300–800 KB |
| Scanned document (300dpi) | 2550×3300 | ~3–8 MB | ~25 MB | ~600 KB–5 MB |
| Logo with transparency | 800×400 | ~200–500 KB | ~1 MB | ~20–100 KB |
PNG's DEFLATE compression is particularly efficient for images with large uniform areas (screenshots, logos, graphics) — it can be 5-10x smaller than uncompressed TIFF for these cases. For photographs with continuous tonal variation, TIFF with LZW and PNG produce similar sizes. Uncompressed TIFF should only be used when maximum read/write speed is required and storage isn't a concern.
Use Case Decision Matrix
| Use Case | Best Format | Why |
|---|---|---|
| Web graphics (logos, icons) | PNG | Universal browser support; alpha transparency; small size |
| Screenshots | PNG | Lossless, small, universally openable |
| Professional photography archive | TIFF | 16-bit color preservation; full EXIF/IPTC metadata; Lightroom/Photoshop integration |
| Commercial printing | TIFF | CMYK color mode; print shops require TIFF or PDF for raster images |
| Scanner output (documents) | TIFF | Multi-page TIFF is standard; lossless; batch scanning workflows |
| Multi-page document image | TIFF | Single TIFF file can hold multiple pages; no PNG equivalent |
| Image with layers (Photoshop) | TIFF | Adobe TIFF saves Photoshop layer data; PSD also works but TIFF is more portable |
| Web favicon / icon | PNG | PNG at 32-bit with alpha is the standard web icon format |
| Medical imaging | TIFF | 32-bit float TIFF used for radiological data |
| Source file for web delivery | TIFF (master) → WebP/PNG/JPG (delivery) | Keep TIFF as archive; convert to web format for delivery |
Software and Browser Compatibility
| Software / Platform | TIFF | PNG |
|---|---|---|
| Chrome / Firefox / Edge | No native support | Full native support |
| Safari (macOS) | Limited (Safari 17 added basic support) | Full native support |
| Windows Photos app | Full | Full |
| macOS Preview | Full | Full |
| Adobe Photoshop | Full (preferred format) | Full |
| Adobe Lightroom | Full (round-trip editing) | Export only |
| Figma / Sketch / design tools | Import only (limited) | Full (native) |
| Microsoft Office | Import supported | Full |
| Print shops / RIP software | Full (industry standard) | Generally supported but TIFF preferred |
When to Use TIFF vs PNG
Use TIFF When...
- Working in professional photography post-processing — Lightroom exports to TIFF for round-trip editing with Photoshop; layers and 16-bit depth are preserved
- Preparing images for commercial printing — Print shops use TIFF for high-res raster images; CMYK color mode support is essential
- Scanning documents or photos — Scanners default to TIFF (often multi-page); preserve maximum scan quality
- Archiving 16-bit or 32-bit images — HDR photography, medical imaging, satellite imagery — all require more than PNG's 8-bit per channel for web (PNG supports 16-bit but most web workflows ignore the extra depth)
- Multi-page image documents — TIFF can hold multiple pages in one file (fax, scanned documents, multi-page artwork)
Use PNG When...
- Web graphics, logos, icons — Universal browser support, small file size, full alpha transparency
- Screenshots — Lossless capture without JPEG artifacts; everyone can open it
- Graphics with text or hard edges — PNG's lossless compression avoids JPEG's ringing artifacts around text
- Sharing images with general audiences — TIFF won't open in browsers; PNG opens everywhere
- Source for web delivery pipeline — PNG is the standard input format for web image optimization (compress to WebP for delivery)
Convert TIFF to PNG (or PNG to TIFF) with ChangeThisFile
ChangeThisFile supports TIFF ↔ PNG conversion via /tiff-to-png and /png-to-tiff. Both conversions are lossless (both formats are lossless). TIFF to PNG reduces file size significantly; PNG to TIFF increases file size but gains TIFF's professional metadata and CMYK support.
