How to Convert TIFF to PNG

TIFF is a lossless professional format used in print workflows, scientific imaging, and photography. PNG is also lossless but far more compatible — every app and browser supports it. Converting TIFF to PNG preserves image quality while making the file universally usable. Transparency is preserved in both directions.

Step-by-step instructions

  1. 1

    Convert on Mac with Preview

    Open the TIFF in Preview. Go to File → Export. Choose PNG from the Format dropdown. Click Save. Preview handles multi-layer and multi-page TIFFs — it exports the visible state. For CMYK TIFFs from professional workflows, Preview converts to RGB automatically.

    Convert on Windows with Paint or Photos

    Right-click the TIFF → Open With → Paint → File → Save As → PNG picture. Or open in Photos and save as PNG. For better control and transparency preservation, use GIMP (free) or FFmpeg: `ffmpeg -i input.tiff output.png`.

  3. 3

    Batch convert with FFmpeg or ImageMagick

    FFmpeg: `ffmpeg -i input.tiff output.png`. Batch on Linux or Mac: `for f in *.tiff; do ffmpeg -i "$f" "${f%.tiff}.png"; done`. ImageMagick: `convert input.tiff output.png` or batch: `mogrify -format png *.tiff`. ImageMagick handles multi-page TIFFs by creating numbered PNG files.

  4. 4

    Verify the conversion

    Check that colours look correct — CMYK-to-RGB conversion may shift colours slightly. If the TIFF had layers from Photoshop, only the flattened image appears in PNG. For TIFF files with embedded ICC colour profiles, ensure your converter preserves or converts the profile to sRGB for correct web display.

Why convert TIFF to PNG?

TIFF files from scanners, cameras, or print workflows are enormous and incompatible with web browsers. Converting to PNG gives you a lossless, universally compatible file that's 30–50% smaller than TIFF while preserving every pixel.

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Does TIFF to PNG lose quality?
No — both TIFF and PNG are lossless formats. Converting TIFF to PNG preserves every pixel exactly. The only potential change is colour space conversion (CMYK TIFF → RGB PNG) which may alter colours slightly but without adding compression artefacts.
What is the difference between TIFF and PNG?
Both are lossless raster formats, but TIFF is primarily used in professional and print workflows and supports features PNG doesn't: multiple layers, pages, CMYK colour space, and high bit-depth. PNG is designed for web and screen use — universal compatibility, smaller files, and transparency support. For web use, always prefer PNG over TIFF.
Can I convert a multi-page TIFF to PNG?
Yes — ImageMagick converts each page to a separate numbered PNG file: `convert multipage.tiff page_%d.png`. FFmpeg converts only the first frame. For multi-page TIFF documents common from scanner output, ImageMagick or Ghostscript give the most control.
