Convert TIFF to PNG

PNG keeps a TIFF scan's full detail without loss, but in a format every browser, document editor and website understands.

  • Never uploaded
  • Instant, no sign-up
  • Works offline

Drop images here

Files stay in your browser — nothing is uploaded.

About this tool

The TIFF is decoded in your browser with a built-in TIFF reader, then saved as a lossless PNG. Large, uncompressed scans often get noticeably smaller too. Drop your TIFF files below: each one is decoded and re-encoded as PNG by your own browser, so even private images never leave your device.

How it works

  1. 1

    Add one or more TIFF files (or try the sample).

  2. 2

    They're converted to PNG automatically.

  3. 3

    Download each PNG or everything as a ZIP.

  • Batch conversionConvert dozens of files at once; work runs in background workers so the page stays responsive.
  • No size capsThere are no upload limits — only your device's memory sets the ceiling.
  • Private by designEverything runs on your device. No uploads, no account, no watermark, and EXIF/GPS data is stripped from the result.

Supported formats

Input: TIFF (and other common image formats). Output: PNG.

Frequently asked questions

How do I convert TIFF to PNG?

Drop your TIFF files onto the converter. They're converted straight away; press Download to save the PNG files or a ZIP.

Is TIFF to PNG lossless?

Yes for 8-bit images. 16-bit TIFFs are reduced to 8 bits per channel, which is what PNG viewers and the web use.

Can I convert several files at once?

Yes. Add as many as your device can hold in memory and download them together as a ZIP.

Are my images uploaded to a server?

No. Files are decoded, processed and re-encoded by your browser using the canvas API and Web Workers. Nothing is sent to any server, and there is no account or storage. Closing the tab discards everything.
