Convert TIFF to PNG
Convert TIFF to PNG online, free and 100% in your browser. No upload, no signup. All the work happens on your device, so files can be as large as it can handle.
How to convert an image
- Drop or pick your TIFF file, or paste it with Ctrl/⌘+V.
- PNG is already selected: output is lossless, fully optimized.
- Convert, compare the before/after, and save, all on your device.
Why convert to this format?
TIFF is a lossless format used in print and scanning workflows, high quality but far too large for the web. PNG is a lossless format with an alpha channel, pixel-perfect for logos, screenshots and line art.
OptImg runs the same high-quality engines desktop tools use, so you get desktop-grade PNG output at a sensible default (lossless output), adjustable at any time, without ever uploading your image.
Your TIFF is decoded, re-encoded to PNG and handed straight back, ready to save, all in an instant on your device: no server sees a single byte, which is why there's no queue and files can be as large as your device can handle.
Frequently asked questions
- Is my TIFF uploaded to a server?
- The TIFF-to-PNG conversion runs at native speed entirely in your browser: nothing is uploaded, your file never leaves your device, there is no queue, and no size limit beyond your device's memory.
- Will converting to PNG change the image?
- PNG output is lossless, so every pixel the decoder reads is preserved exactly, and the file is fully optimized for the smallest lossless size. A “smaller file” toggle can quantize to a palette when you want extra savings.
- Is the TIFF to PNG converter free?
- Yes: completely free, with no signup, no watermark and no cap on how many files you convert. There is nothing to install; it runs in your browser.
