TIFF to PNG Converter

Your TIFF will not display in a browser or a web tool, but you do not want to throw away detail by saving a JPG. PNG is the lossless option that almost every site and design program accepts. This converter reads the first page of your TIFF and writes it as a PNG without sending it anywhere.

How to convert TIFF to PNG

  1. Add your TIFF files by dropping them, clicking the drop zone or pasting.
  2. The output format is already set to PNG. Adjust quality or size if you need to.
  3. Press Convert and compare the original and new size for each file.
  4. Download each file or all of them as a ZIP.

When to convert, and when not to

  • You need a web-friendly copy of a scan, diagram or screenshot stored as TIFF, without adding lossy compression.
  • A design tool, content system or form accepts PNG but not TIFF.
  • The TIFF has a transparent area you want to keep.
  • Do not expect a small file: a PNG from a photographic TIFF can be large, and JPG or WebP is lighter if some loss is acceptable.

What changes

  • Only the first page of a multi-page TIFF is converted.
  • Pixels are stored without loss, so the PNG matches what the tool read from the TIFF.
  • Sixteen-bit files are reduced to the eight-bit range this converter writes.
  • If the TIFF carries an alpha channel, its see-through areas are kept in the PNG.
  • There is no quality slider, and metadata and colour profiles are not written.

Why a PNG is the safe web copy of a TIFF

Browsers do not display TIFF files, so a TIFF placed on a web page shows nothing or offers a download. PNG is built for the web and supports transparency, which is why it is the usual stand-in for diagrams, logos and screenshots that were stored as TIFF. The pixels are copied across exactly, with no new compression loss.

For photographs the trade-off is size. Lossless storage of detailed photographic pixels takes more space than lossy storage, so a PNG may end up close to, or even larger than, a compressed TIFF. Check the sizes shown beside each file on your own images.

Keeping transparency

TIFF files can carry an alpha channel for see-through regions. When this tool finds one, it carries it into the PNG, so a cut-out logo keeps its edges. If the file has no alpha channel, the PNG is fully opaque. You can open the result on a coloured background in any viewer to confirm which parts are transparent.

Resizing before you publish

The options panel can scale the image by percent or to a maximum width and height. TIFF scans are often far larger than a web page needs, and reducing the pixel size is the dependable way to shrink a PNG, since there is no quality dial. Test with one file first, then run the batch.

When to pick another format

If the picture is a photograph meant for a web page, JPG or WebP will usually give a lighter file. PNG makes most sense for sharp edges, text, flat colours and anything with transparency. You can change the output format in the same options panel and convert again without adding the file a second time.

Archiving and sharing at the same time

Many teams keep the TIFF as the archive and publish a PNG beside it. The PNG is easy to link, preview and attach, while the TIFF stays untouched for print. This tool keeps your original file name and changes only the extension, so the two files are easy to tell apart.

Privacy: your files stay on your device

  • The tool decodes, resizes and encodes your pictures with your browser. The files are never sent to a server.
  • To check it yourself: open the browser developer tools (F12), open the Network tab, convert a file, and look for any request that carries your image. You will see none.

Frequently asked questions

Does PNG lose any quality compared with the TIFF?

No new loss comes from the format change. The PNG holds the pixels the tool read, although sixteen-bit values are reduced to eight-bit.

Why is my PNG bigger than I expected?

Lossless storage of photographic detail needs more space than lossy storage. Compare the sizes, or try WebP or JPG if a small loss is fine.

Why did I get one page from my multi-page TIFF?

Only the first page is read. Split the pages in a scanning program first, then convert each file.

Can this keep a transparent background?

Yes, when the TIFF has an alpha channel. A TIFF without one gives a fully opaque PNG.

Which TIFF files can it read?

Common 8-bit and 16-bit files with the usual compressions. Unsupported ones give a clear message rather than a damaged picture.

Is the PNG a good archive copy?

It is lossless for the 8-bit data the tool read, but it drops metadata and page information. Keep the TIFF as the archive and use the PNG for sharing.
