PNG compression

Lossless. Higher effort finds smaller files but takes longer.

Transparency

Transparent areas are filled with this colour, so the result has a solid background.

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

How to use the TIFF to PNG

  1. Click “Choose Files” or drop your images into the box above. Whole folders work too.
  2. Adjust the Advanced settings if you need to, then click “Convert”.
  3. When the row shows Done, click “Download” — or “Download all” for a ZIP.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

This page opens the Image Converter pre-set to PNG with TIFF decoding built in.

Conversion is lossless and local — archival files never leave your device.

This is a pre-set view of the Image Converter. Every option in the toolbar can still be changed.

Frequently asked questions

TIFF to PNG or JPG?

PNG for documents, line art and anything you’ll edit again — it keeps every pixel. JPG for photographs headed to the web or chat, at a fraction of the size.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
