Free TIFF to PNG Converter Online — Lossless, No Upload

Converting TIFF to PNG is a genuinely lossless operation — both formats store image data without discarding any pixels, so the conversion preserves every detail exactly. The main reason to convert is compatibility: TIFF files aren't supported in web browsers, most CMSs, or apps on iOS and Android, while PNG is universally understood everywhere.

Drop your .tiff or .tif file into the converter above and get a PNG that's identical in quality — often 2–5x smaller than the original TIFF, with full support everywhere it needs to go.

TIFF to PNG: what happens to the quality?

Nothing is lost. TIFF and PNG are both lossless formats. Converting between them is like moving a file from one folder to another — the content doesn't change, only the container.

The file size reduction comes from PNG's more efficient compression algorithm, not from discarding image data. Uncompressed TIFFs compress well to PNG because PNG's DEFLATE compression is designed for exactly this type of data. LZW-compressed TIFFs may produce PNGs of similar size since both are already using lossless compression.

A practical example: a 50MB uncompressed TIFF might become a 10–20MB PNG. A 20MB LZW-compressed TIFF might become an 18MB PNG. Both are smaller, neither loses any image quality.

This is the key advantage over TIFF-to-JPG conversion: you get universal compatibility without the quality trade-off. If you need to edit the PNG later, there's no accumulating quality loss from repeated saves.

How to convert TIFF to PNG (step by step)

1. Open the converter above in any browser.
2. Drop your .tiff or .tif files into the drop zone, or click to select them.
3. Click Convert. The conversion runs locally in your browser — no upload occurs.
4. Download each PNG file. If you converted multiple files, use "Download All" for a zip archive.

The entire process takes under 10 seconds for most files. A 50MB TIFF typically converts in 3–8 seconds on a modern device. Very large files (200MB+) may take 30–60 seconds.

Nothing you convert is stored, logged, or accessible by anyone else. When you close the browser tab, the session is gone.

For batch conversion of many files at once, see the batch TIFF to PNG guide.

TIFF vs PNG: when PNG is clearly the better choice

PNG wins over TIFF in almost every web and sharing scenario:

Scenario	TIFF	PNG
Website / CMS upload	Not supported	Universal support
iOS or Android viewing	No native support	Supported everywhere
Email attachment preview	Doesn't inline	Displays inline
Image with transparent background	Supported but rare	Designed for this
Screenshot or UI graphic	Unnecessarily large	Ideal format
Lossless archival	Industry standard	Acceptable alternative
Print production (commercial)	Required at 300 DPI	Sometimes accepted

The short version: convert TIFF to PNG when the file needs to be usable in the web ecosystem. Keep the TIFF when you're in a print or archival workflow.

CMYK TIFF handling — automatic conversion to RGB

CMYK TIFFs are common outputs from Photoshop, InDesign, and print production workflows. PNG doesn't support CMYK — it's an RGB format. The converter handles this automatically: CMYK TIFFs are converted to RGB before being encoded as PNG.

The result looks correct on screen. Some colors, particularly vibrant reds and certain saturated hues, may shift slightly because the CMYK and RGB color gamuts don't overlap perfectly. For standard photos and graphics, this difference is negligible. For critical color matching between print and screen, use Photoshop with ICC profile management.

The converter also handles grayscale TIFFs (output as grayscale PNG, smaller file size) and RGB TIFFs (straight format conversion, no color space change needed).

When to convert to JPG instead of PNG

PNG keeps every pixel but produces larger files than JPG for photographic content. For photos going to the web, JPG is usually the better choice:

• A portrait photo as PNG: 8–15MB. The same photo as JPG quality 90: 3–6MB. Both look identical on screen.
• A product shot with a white background as PNG: 4–8MB. As JPG quality 88: 1–2MB.

Use PNG over JPG when:

• The image needs transparency (logos, icons, UI elements with transparent backgrounds)
• The image contains text, sharp lines, or flat graphics where JPG artifacts would be visible
• You'll continue editing the file and want to avoid any quality degradation
• The image is a screenshot, diagram, or chart

For photos without transparency that need maximum web compatibility, see the TIFF to JPG converter for the smaller file size option.

Frequently Asked Questions

Does TIFF to PNG conversion lose any quality?

No. Both TIFF and PNG use lossless compression. Every pixel in the TIFF is preserved exactly in the PNG output. The file size reduction comes from PNG's more efficient compression algorithm, not from discarding image data.

How much smaller will the PNG be compared to the TIFF?

For uncompressed TIFFs, expect 2–5x smaller as PNG. A 50MB uncompressed TIFF typically becomes 10–25MB PNG. For LZW-compressed TIFFs, the PNG may be similar in size since both are already using lossless compression. The reduction varies significantly by image content — flat graphics compress much better than complex photographic detail.

Can I convert .tif files as well as .tiff files?

.tif and .tiff are the same format — just different file extension conventions. The converter accepts both. You may encounter .tif (four letters, older convention) and .tiff (five letters, more common today). Either works.
