Short answer: both are lossless, but solve different problems. PNG is the web-native lossless format — universal browser support, alpha transparency, ZIP compression, 8 or 16-bit depth. TIFF is the print/archival/professional editing format — multiple color spaces (CMYK!), layers, 32-bit float, multi-page support, and the industry standard for digitization workflows.
For screen use (websites, apps, screenshots, icons): PNG. For print, photo editing masters, archival, or CMYK workflows: TIFF. PNG files are typically 2-5× smaller than the equivalent TIFF for the same content.

When should you use PNG vs TIFF?
.PNG Use when…
- Screenshots and screen captures — universal web display, smaller than TIFF
- Logos and icons — sharp edges preserved, alpha transparency
- UI mockups for client review — looks identical on every browser
- Diagrams, charts, infographics — solid colors compress well in DEFLATE
- Web hero images with transparency — overlay graphics, watermarks
- App icons (mobile, desktop) — required format for many app stores
.TIFF Use when…
- Print preparation — CMYK color space native, no compression artifacts at large scale

Strengths Comparison
.PNG Strengths
- Lossless compression — every save preserves the original pixels perfectly.
- Full 8-bit alpha channel for smooth transparency.
- Excellent for text, UI screenshots, logos, and line art.
- Royalty-free and an ISO standard (ISO/IEC 15948).
- Supports 16-bit color depth for high-fidelity work.
.TIFF Strengths
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Limitations
.PNG — Limitations
- Much larger than JPEG for photographs (no perceptual compression).
- No native animation in most software (APNG support is inconsistent).
- No CMYK support — web and screen only, not print.
- Metadata capabilities are less rich than JPEG's EXIF.
.TIFF — Limitations
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.
- Weak animation support — designed for still imagery.
Technical deep dive: PNG vs TIFF
Two lossless formats for very different audiences
PNG (Portable Network Graphics, 1996) and TIFF (Tagged Image File Format, 1986) are both lossless raster image formats that preserve every pixel exactly. But they evolved for opposite ecosystems and have very different feature priorities. PNG is the web's lossless image format: lightweight, with alpha transparency, designed for online distribution. TIFF is the print/photography lossless format: heavyweight, with extensive metadata support, designed for professional production workflows.
The choice between them depends on your audience: web users (PNG) vs print/production professionals (TIFF).
When PNG is the right choice
-
Any web image needing lossless quality: graphics, logos, screenshots, charts, technical diagrams, UI mockups. PNG is the web standard for lossless raster.
-
Images needing transparency: PNG-32 supports full alpha channel transparency. Essential for icons, logos overlaid on varied backgrounds, design composition layers.
-
Cross-platform sharing: every browser, every OS, every email client opens PNG natively. TIFF support varies — many web browsers don't display TIFF inline.
-
Smaller file sizes for web content: PNG's compression (DEFLATE) is more efficient than TIFF's typical compression options for web-style graphics. A web screenshot is usually 30-50% smaller as PNG than as TIFF.
-
Email attachments: PNG attachments preview inline in Gmail, Outlook, Apple Mail. TIFF often triggers "file format not previewed" or downloads instead.
-
Embedding in documents: PNG embeds well in Word, PowerPoint, Google Docs, web pages. TIFF embedding is patchy in many tools.
-
Modern web optimization: while WebP and AVIF beat PNG in compression for new content, PNG remains the universal lossless fallback that works everywhere.
When TIFF is the right choice
-
Professional photography: photographers archive RAW files and export TIFF for editing in Photoshop, Lightroom, Capture One. TIFF preserves every nuance from RAW conversion.
-
Print and prepress: commercial printing standardizes on TIFF for high-quality reproduction. Magazines, books, posters, brochures — print shops expect TIFF.
-
Scientific imaging: astronomy (FITS-like data), medical imaging, satellite imagery, microscopy. TIFF supports unusual color depths (16-bit, 32-bit per channel), multiple color spaces (RGB, CMYK, LAB), and extensive metadata for scientific accuracy.
-
CMYK color space: TIFF natively supports CMYK (the color space used in printing). PNG only supports RGB. For print workflows where CMYK matters, TIFF is essential.
-
High bit-depth images: 16-bit per channel images for HDR photography, scientific imaging, or professional editing where banding in 8-bit color would be visible. TIFF handles 16-bit natively; PNG supports 16-bit but with less universal tool support.
-
Layered editing files: TIFF can store Photoshop-style layers, alpha channels, and editing history. PNG is single-layer only.
-
Long-term archival of important images: TIFF has 35+ years of guaranteed support and is the format of choice for national archives, museums, libraries digitizing collections.
-
Multi-page documents: TIFF can hold multiple pages in a single file (used in fax workflows and document scanning). PNG is single-page only.
The compression difference
Both formats support multiple compression options, with very different defaults:
PNG compression:
- Always lossless (no quality loss possible)
- Uses DEFLATE algorithm (same as ZIP) with PNG-specific optimizations (palette quantization, line filtering)
- Typically 30-50% smaller than uncompressed for web-style graphics
- Always-on, no decision required
TIFF compression:
- Multiple options: uncompressed, LZW (lossless), ZIP (lossless), JPEG (lossy), PackBits (lossless)
- Often used uncompressed in production workflows for maximum editing performance
- LZW or ZIP for moderate compression with no quality loss
- JPEG for smaller files when some quality loss is acceptable
- Choice matters: an uncompressed TIFF can be 5-10× larger than the same image as PNG
For web sharing, PNG's standardized compression is more predictable. For production work, TIFF's options give professionals control.
Conversion mechanics: PNG → TIFF
The conversion is straightforward and lossless: PNG's pixel data is preserved exactly. KaijuConverter's PNG → TIFF supports:
- Compression options: LZW (default, good balance), ZIP (best lossless compression), uncompressed (maximum editing performance), JPEG (smaller files with some quality loss)
- Bit depth preservation: 8-bit PNG → 8-bit TIFF; 16-bit PNG → 16-bit TIFF
- Transparency: PNG alpha channel preserved as TIFF alpha
- Color space: RGB preserved; conversion to CMYK requires explicit setting (since TIFF supports both but PNG only RGB)
- Metadata: ICC color profiles, EXIF data preserved
Conversion mechanics: TIFF → PNG
Also lossless and straightforward, with caveats:
- Standard TIFF (RGB, 8-bit): converts to PNG perfectly. No quality loss.
- CMYK TIFF: must be converted to RGB for PNG. Color shifts may occur (CMYK has wider gamut for print colors than sRGB). KaijuConverter uses standard ICC profile-aware conversion to minimize differences.
- 16-bit TIFF: converts to 16-bit PNG (preserved) or 8-bit PNG (some banding may appear in gradients).
- Multi-page TIFF: KaijuConverter generates one PNG per TIFF page, packaged as ZIP.
- Layered TIFF: layers are flattened into a single composite image (PNG is single-layer).
- Compression: TIFF compression is decoded and PNG re-compresses with its own algorithm.
File size comparison reality
For the same lossless quality:
- Web screenshot, 1920×1080: PNG ~400 KB, TIFF (LZW) ~600 KB, TIFF (uncompressed) ~6 MB
- Photographic image, 4000×3000: PNG ~12 MB, TIFF (LZW) ~18 MB, TIFF (uncompressed) ~36 MB, JPEG (Q90) ~3 MB
- Logo with transparency, 512×512: PNG ~30 KB, TIFF (LZW) ~50 KB
For identical quality, PNG is consistently smaller for graphics. TIFF's larger size buys you metadata richness, multi-page support, and broader bit-depth/color-space options.
Pro tip: which to use for what
- Distributing or sharing: PNG every time (smaller, more compatible)
- Editing professionally in Photoshop: TIFF (preserves layers, metadata, color spaces)
- Printing professionally: TIFF (CMYK support, high bit-depth, print workflow expects it)
- Web display: PNG (always, until WebP/AVIF reaches 100% browser support)
- Archival of important images: TIFF (more metadata) or PNG-16 (smaller, also very long-term safe)
- Scientific data with unusual color spaces: TIFF (only viable choice)
Frequently Asked Questions
For sharing and web use, PNG (smaller files, universal compatibility). For professional editing in Photoshop or printing, TIFF (better metadata, layer support, CMYK color space, broader bit-depth support). For long-term archival, both work well; TIFF has slightly better metadata richness.
TIFF is often used uncompressed by default in production workflows for maximum editing performance. PNG is always compressed (lossless). Save your TIFF with LZW or ZIP compression to get similar size to PNG. For web sharing, PNG is consistently smaller for graphics.
No. Both are lossless — every pixel is preserved exactly. The conversion just rewraps the same pixel data in a different container. TIFF gains you metadata richness (ICC profiles, EXIF, layers if writing them) but doesn't add quality. The original PNG's quality is the ceiling.
Generally no, despite TIFF being older than the web. Most browsers (Chrome, Firefox, Edge) don't display TIFF inline — they trigger downloads. Safari has limited TIFF support. For web display, convert TIFF to PNG, JPEG, or WebP first. PNG is the most universal lossless option.
Three reasons: (1) TIFF supports CMYK color space natively (the color model printers use), (2) TIFF supports high bit-depth (16-bit per channel) for smooth gradients, (3) TIFF is the established standard in prepress workflows. PNG is fine for office printers but professional printing pipelines expect TIFF.
Usually but not always. TIFF supports multiple compression options including JPEG-compressed TIFF which is lossy. Most professional TIFFs use LZW (lossless), ZIP (lossless), or no compression. Always check compression settings if you need lossless quality. KaijuConverter defaults to LZW for new TIFF outputs.
PNG (Portable Network Graphics) is a lossless raster image format created in 1996 as a patent-free alternative to GIF. It supports transparency, making it ideal for logos, icons, and web graphics.
PNG files open natively in all modern operating systems, web browsers, and image editors including Photoshop, GIMP, Paint.NET, and Canva.
