Turn your ICO images into TIFF right in the browser — this tool will grow each file and hand it back in seconds, with nothing uploaded to any server. ICO is the Windows icon and favicon format, holding one or more small square images up to 256×256. TIFF is the print and archival standard, storing images losslessly at high bit depth for professional workflows. The conversion keeps your image faithful while switching it into the TIFF container. Free, private, unlimited, and watermark-free.
How to Convert ICO to TIFF
Add your ICO files
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.
Convert to TIFF
Press Convert. TIFF is lossless, so every pixel is preserved exactly.
Download
Save each TIFF file, or grab them all as a ZIP. Nothing was ever uploaded, so nothing needs deleting.
Why convert ICO to TIFF?
The main reason is printing, scanning and archival, where maximum quality matters more than file size. ICO excels at favicons and Windows application icons, but when you need pixel-perfect quality, TIFF is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
TIFF is a lossless format, so the conversion preserves your image exactly — no detail is discarded in the TIFF encoding itself.
A note on file size
Note that TIFF files are usually larger than ICO — TIFF stores up to 48-bit colour, often uncompressed, so this trades size for compatibility.

Tips & Things to Know
Check the file size after converting
Note that TIFF files are usually larger than ICO — TIFF stores up to 48-bit colour, often uncompressed, so this trades size for compatibility. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Transparency is preserved
Both formats support an alpha channel, so any transparent regions in your ICO stay transparent in the TIFF — nothing is flattened onto a solid background.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your ICO files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
The conversion is faithful
TIFF is lossless, so every pixel is preserved exactly as it was in your ICO, meaning you do not have to worry about settings — just convert and download.
Frequently Asked Questions
How do I convert ICO to TIFF for free?
Add your ICO file above and press Convert. The TIFF download appears in seconds. It is completely free, with no signup, no limits and no watermark.
Is my ICO uploaded to a server?
No. The entire conversion runs inside your browser using your device's own processor, so your images never leave your computer. That matters for private photos and confidential work.
Can I convert multiple ICO files at once?
Yes. Add as many as you like and they are converted in one batch, then offered individually or as a single ZIP download.
Will converting to TIFF reduce quality?
No. TIFF is lossless, so the conversion keeps every pixel. Any quality limit comes only from the original ICO, not from this step.
Does TIFF support transparency?
Yes, TIFF supports an alpha channel, so transparent areas in your image are preserved.
Why is my TIFF file larger than the ICO?
TIFF stores up to 48-bit colour, often uncompressed without lossy compression, so it is naturally larger than ICO. This is expected and the image quality is fully intact.
What is the difference between ICO and TIFF?
ICO is the Windows icon and favicon format, holding one or more small square images up to 256×256. TIFF is the print and archival standard, storing images losslessly at high bit depth for professional workflows. That difference is what this conversion is really about.
Is there a file size limit?
Because processing happens in your browser, very large images depend on your device's memory, but typical photos convert instantly. Nothing is capped by an upload limit.
Do I need to install anything?
No. This works in any modern browser on any device — Windows, Mac, Android or iPhone — with nothing to install.
Is this ICO to TIFF converter really free?
