About converting TIFF to PNG
TIFF (.tiff) files can be converted to PNG entirely in your browser — no software to install, no file upload, and no account required. The conversion runs on a WebAssembly build of ffmpeg directly on your device.
Technical comparison
| TIFF | PNG | |
|---|---|---|
| Category | image | image |
| Compression type | Lossless (or uncompressed) | Lossless (DEFLATE) |
| Typical file size | Large — high bit depth and often lossless compression | Moderate — larger than JPEG for photos, smaller for flat-color graphics |
| Transparency support | Yes | Yes (full 8-bit alpha channel) |
How to convert TIFF to PNG privately
Every step below runs on a WebAssembly build of ffmpeg inside this browser tab. Your .tiff file is never uploaded to a server — there's no network request carrying it anywhere.
Add your TIFF file
Drag and drop, or click to select, a file (.tiff). It's read straight from disk into browser memory — no upload step exists.
Convert locally
FreePrivateConvert converts it to PNG using a WebAssembly build of ffmpeg, entirely within this browser tab.
Download the result
Save your converted .png file. It only ever existed in this tab's memory — closing the tab without downloading discards it completely.
Convert TIFF to PNG with ffmpeg (command line)
Prefer the terminal? This is the exact ffmpeg command this page runs for you:
ffmpeg -i input.tiff output.png- -i input.tiff
- Your TIFF file.
- output.png
- The PNG file to create. ffmpeg picks the container from this extension.
Don't have ffmpeg installed? You don't need it: use the converter at the top of this page. It runs the same conversion on your own device, and your file is never uploaded.
FAQ
- Is my file uploaded anywhere?
- No. Your file is read and processed inside this browser tab and never leaves your device. You can confirm it in your browser's developer tools: the Network tab shows no upload.
- Does converting TIFF to PNG reduce quality?
- No. PNG is lossless, so the TIFF's pixels are kept exactly.
- Is there a file size limit?
- Yes: 500MB per file. There's no account and no limit on how many files you convert.
- What's the difference between TIFF and PNG?
- TIFF (Tagged Image File Format) and PNG (Portable Network Graphics) store data differently. TIFF: lossless (or uncompressed). PNG: lossless (DEFLATE). PNG is a lossless, compressed image format with full alpha transparency — the standard choice for graphics, screenshots, and anything with sharp edges or text.
- Why convert TIFF to PNG?
- Common uses for PNG: Screenshots; Logos and icons; UI/design assets requiring transparency. Lossless DEFLATE compression means no artifacts around text, logos, or hard edges, unlike JPEG.
- What MIME type does a .png file use?
- image/png, the standard type for Portable Network Graphics.
- What is the ffmpeg command to convert TIFF to PNG?
- Run: ffmpeg -i input.tiff output.png. This is the exact command FreePrivateConvert runs for this conversion, so you can use this page instead of installing ffmpeg: it runs the same conversion inside your browser.
