TIFF to PNG: Two Different Files Hiding Behind the Same Extension
A .tiff file could mean two fairly different things depending on where it came from, and which one you have changes what to expect from converting it. Check which situation actually applies before you run anything through the tool.
If it's a single scanned photo or a camera export
This is the straightforward case, and PNG is a solid destination for it. Both TIFF and PNG are commonly used without throwing away image data, so unlike converting to JPG, you're not trading quality for size here. The size reduction you'll see going from TIFF to PNG is real but modest, since TIFF files are frequently saved with light or no compression at all, while PNG always runs its DEFLATE compression on the way out. It shrinks the file without touching a single pixel, just nowhere near as dramatically as switching to a lossy format would.
One place PNG actually keeps up with TIFF that JPG can't: bit depth. If your TIFF was exported at 16 bits per color channel, common on professional camera raw workflows and scanning equipment built for archival quality, PNG can store that same 16-bit depth. JPG caps out at 8 bits and would flatten that extra tonal detail away. If preserving that range matters for what you're doing, PNG is the format that keeps it, not JPG.
If it's a scanned multi-page document
This is the case worth pausing on. TIFF is one of the few image formats that can hold multiple pages inside a single file, which is exactly why scanners default to it for multi-page documents instead of producing a folder full of separate images. PNG has no equivalent concept. It's one image, period. So converting a multi-page TIFF to PNG pulls out a single page, typically the first one, and the rest of the document doesn't come along for the ride.
If that's not what you expected, the fix isn't a setting inside this converter, it's recognizing that PNG was never going to be able to hold the rest of the pages in the first place. A multi-page scan that needs to stay multi-page belongs in a format built to keep pages together, like PDF, not a single-frame image format.
One converter, more than one destination
If PNG turns out not to be the right destination for what you're trying to do, whether that's needing something smaller for the web, needing transparency support you don't have yet, or just needing a different format entirely, the same upload queue on the TIFF converter lets you pick a different output from the dropdown next to your file: JPG, WebP, AVIF, SVG, JFIF, GIF, ICO, or another TIFF, without starting over from scratch.
Lossless Fidelity
PNG uses byte-exact DEFLATE compression to pack uncompressed TIFF bitmap channels into compact files with zero generation loss.
Format Highlights
- 16-Bit Color Depth: Preserves deep tonal gradations without 8-bit clipping.
- Full Transparency: Retains alpha channels from layered graphic workflows.
- Broad Compatibility: Compatible with all operating systems, design apps, and web browsers.
Single-Frame Output
Multi-page TIFF documents will extract the primary cover frame. If multi-page binding is required, consider PDF export.
Large archival TIFF files are decoded and re-encoded locally in your browser memory. No data is ever sent across the network.
