What TIFF to PNG does
Convert TIFF images to PNG without losing a pixel. TIFF is the lossless format that scanners, cameras and print workflows produce; PNG is the lossless format that browsers, web pages, chat apps and office software actually open. This tool decodes each TIFF in your browser — including multi-page files, which become one PNG per page in a ZIP — and writes PNGs with transparency preserved. Nothing is uploaded.
Why PNG rather than JPG
| Choose PNG when | Choose JPG when |
|---|---|
| The TIFF has transparency (alpha channel) | It is a photograph and size matters |
| It is a scan of text, line art, a diagram or a map | It will be emailed or uploaded with a size limit |
| Every pixel must survive (archival, legal, medical) | A little loss is fine and files must be small |
| It is a screenshot or rendered graphic | The recipient asked for JPG |
For photographs, PNG files are large — a 300 dpi A4 colour scan is 15–20 MB as PNG and 1–2 MB as JPG. Use TIFF to JPG for those unless losslessness is required.
What is preserved
- Exact pixel values for 8-bit images. 16-bit TIFFs are scaled to 8-bit PNG (browsers cannot write 16-bit PNG).
- Transparency (alpha channel) — kept as PNG alpha.
- Pixel dimensions, exactly.
- Every page of a multi-page TIFF.
- Not preserved: layers (flattened), CMYK (converted to RGB), the dpi tag, EXIF and GeoTIFF metadata, and ICC colour profiles.
Supported TIFF variants
Uncompressed, LZW, PackBits, ZIP/Deflate, CCITT Group 3 and 4 (fax and bilevel scans) and JPEG-in-TIFF. Greyscale, RGB, RGBA, palette and bilevel colour models. Tiled and stripped layouts. Unusual scientific formats (floating-point samples, more than four channels) are not supported.
Common uses
- Placing scanned drawings, floor plans or maps on a web page or in a presentation.
- Converting fax TIFFs so they display in a browser.
- Getting a transparent logo out of a designer's TIFF for use in a document.
- Preparing archival scans for a viewer that supports PNG but not TIFF.
- Extracting pages from a multi-page TIFF as separate images.
