Frequently Asked Questions
- Does converting TIFF to PNG lose quality?
- No. Both TIFF and PNG support lossless compression. The converted PNG is pixel-identical to the source TIFF — every pixel value is preserved exactly.
- Why is my PNG smaller than the original TIFF?
- PNG uses Deflate compression which typically achieves 40–60% size reduction compared to uncompressed TIFF. The data is all there — just stored more efficiently.
- Why can't I open my TIFF file in a browser?
- Chrome, Firefox, Edge, and Opera do not render TIFF files — they trigger a download instead. TIFF has zero browser support. PNG is the lossless alternative with universal browser compatibility.
- Does PNG support the same color depth as TIFF?
- PNG supports 8-bit and 16-bit per channel, which covers standard photography workflows. TIFF additionally supports 32-bit floating-point per channel, used in HDR and scientific imaging — PNG cannot represent this data, so 32-bit TIFFs convert to 16-bit PNG.
- How are multi-page TIFFs handled?
- Multi-page TIFFs extract to separate PNG files — one per page. A 10-page scanned document TIFF produces 10 PNG files.
- Does TIFF to PNG preserve transparency?
- Yes. Transparency from TIFF files is preserved in the PNG output with full alpha channel support.
- Can I convert multiple TIFF files to PNG at once?
- Yes. Convertify supports batch conversion — upload up to 10 TIFF files and download them all as PNG simultaneously.
Why convert TIFF to PNG?
TIFF is the professional standard for editing and archiving — but no mainstream browser renders it. Chrome, Firefox, Edge, and Opera all trigger a file download prompt when encountering a TIFF. PNG solves this completely: universal browser support, lossless quality, full transparency, and files 40–60% smaller than an equivalent uncompressed TIFF. A 36 MB TIFF typically converts to a 15 MB PNG — pixel-identical, with no quality loss. PNG is also the standard interchange format for design tools: Figma, Sketch, Photoshop, and every web platform accept PNG without configuration.

File size: what to expect after conversion
PNG uses Deflate compression — the same algorithm as ZIP files. On photographic content, a TIFF converted to PNG is typically 40–60% smaller. A 36 MB uncompressed 24-megapixel TIFF becomes roughly 15 MB as PNG. A 144 MB 16-bit TIFF (same photo at full editing depth) produces a PNG around 60–80 MB — still large, because PNG stores all 16-bit channel data losslessly. For comparison, a JPEG of the same image would be 5–8 MB. PNG is the right target when you need lossless quality; if file size is the priority over quality, JPEG or WebP are more efficient. LZW-compressed TIFFs are already partly compressed, so the reduction to PNG is smaller — expect 15–30% rather than 40–60%.
TIFF compression types and how they affect PNG size
TIFF files can be uncompressed, LZW, ZIP/Deflate, or JPEG-in-TIFF. Uncompressed TIFFs produce the largest size reductions when converting to PNG — the PNG compression algorithm typically achieves 40–60% savings on photographic data. LZW-compressed TIFFs are already 1.5–2× smaller than uncompressed, so PNG conversion produces a smaller relative gain. ZIP-compressed TIFFs and PNG use the same underlying Deflate algorithm, so the resulting PNG may be similar in size to the source TIFF or only marginally smaller. JPEG-in-TIFF files have already undergone lossy compression; converting to PNG preserves the degraded data losslessly — the file will be larger than the TIFF source but the image quality cannot be restored.
16-bit TIFF to PNG: preserving editing depth
Professional photographers export 16-bit TIFFs from Lightroom, Capture One, and Photoshop to preserve the full tonal range for editing. PNG supports 16-bit per channel, so the conversion is lossless — all 65,536 tonal values per channel are preserved. A 16-bit TIFF of a 24-megapixel photo weighs 144 MB uncompressed; the converted 16-bit PNG is typically 60–80 MB. Some web and email contexts only support 8-bit PNG — if you need an 8-bit PNG, the conversion will discard the extra depth, which may cause slight banding in images with extreme tonal gradients. Convertify preserves bit depth during conversion.
Multi-page TIFF conversion to PNG
Multi-page TIFF stores multiple images in a single file through chained Image File Directories — a standard format for scanned documents, fax archives, and medical imaging stacks. PNG supports only a single image per file. When converting a multi-page TIFF, Convertify extracts each page as a separate PNG file. A 10-page scanned document TIFF becomes 10 individual PNG files. Document scanning TIFFs often use CCITT Group 4 compression optimized for black-and-white content — these convert to PNG at roughly 1:1 ratio in file size since both formats compress bilevel data efficiently.
TIFF transparency and PNG alpha channel
TIFF supports transparency through an extra alpha channel stored as an additional sample per pixel. PNG also supports an 8-bit alpha channel with smooth semi-transparency. Transparency from TIFF files converts cleanly to PNG. The TIFF transparency model maps directly to PNG's alpha channel — the only difference is that TIFF can store 16-bit alpha while PNG's alpha is 8-bit. In most practical cases this difference is invisible. Convertify preserves transparency during TIFF to PNG conversion.
How Convertify converts TIFF to PNG
Convertify uses a Rust backend with libvips for TIFF to PNG conversion. libvips uses a demand-driven streaming pipeline that processes images without loading the full file into memory — important for large TIFF files that can exceed 100 MB. Color profiles are preserved during conversion. Multi-page TIFFs extract each page as a separate PNG. Files are processed server-side over HTTPS and deleted immediately after download. No account required.
