Why convert TIFF to PNG
PNG is the natural replacement for TIFF when you need a lossless image that works everywhere. Browsers, websites, presentation apps and document editors all handle PNG, while TIFF support is patchy outside professional software. PNG is usually smaller too, because its compression is more efficient than the uncompressed or lightly compressed TIFFs that scanners produce.
Choose PNG over JPG when the image is:
- a scanned document, form or page of text
- a line drawing, map, diagram or chart
- a graphic with transparency
- something you’ll keep editing, where JPG would add loss each time
How to use it
Choose your TIFF files or drop them on the box above. Each is converted on your device; download them one by one or as a ZIP. Click a preview to compare it with the original.
What changes
- Pixels: identical for 8-bit RGB images.
- Bit depth and colour: 16-bit and CMYK become 8-bit RGB.
- Pages: the first page only.
- Layers from editing software are flattened into the visible image.
- Dimensions: unchanged.
Large scans
High-resolution scans can be tens of megapixels. They convert fine on a computer; on a phone, very large images may run out of memory. If a PNG is still bigger than you’d like, the PNG compressor can shrink scans of text dramatically.
Privacy
The conversion runs in your browser with ImageMagick. Your images are never sent anywhere.
TIFF compression versus PNG
Scanners usually save TIFFs uncompressed or with LZW compression. PNG uses DEFLATE compression with filtering tuned for images, which typically gives smaller lossless files for the same pixels. Both are lossless, so the image is identical; you simply get a smaller, more widely supported file.
Converting many scans
Select a whole folder of TIFFs at once. Files are converted one after another so the page stays responsive, and you can download every PNG together in one ZIP. Only the first file waits for ImageMagick to load.
Questions
Is TIFF to PNG lossless?
Yes, for ordinary 8-bit RGB images. PNG stores every pixel exactly. Images with 16 bits per channel or CMYK colour are converted to 8-bit RGB, which looks the same on screen.
Is transparency kept?
Yes. TIFFs with an alpha channel become PNGs with the same transparent areas.
What happens to multi-page TIFFs?
You get the first page as a PNG. To keep all pages in one file, use TIFF to PDF.
Why is the first conversion slower?
The page loads ImageMagick, about 15 MB, the first time a TIFF is converted. It's then cached by your browser.
