How do I convert ICO to JPG?

Add your ICO file to the upload area above, then press Convert. The JPG file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to JPG reduce quality?

JPG uses lossy compression, so some data is discarded. At the default quality the difference is very hard to see or hear; raise the quality setting if you need to be certain, at the cost of a larger file.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

ICO and JPG explained

ICO is a container that holds several versions of the same icon at different sizes, so the operating system or browser can pick the one that fits. It is capped at 256×256 pixels.

JPEG is a lossy image format designed for photographs. It works by discarding detail the human eye is least likely to notice, particularly in colour and in smooth gradients, which is why it compresses photos far better than it compresses text or line art.

Where ICO files come from: Website favicons and Windows application icons.
Where JPG is used: Digital cameras, phone screenshots on Android, and essentially every photo on the pre-2015 web.

ICO vs JPG

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

ICO compared with JPG
Property	Source	Target
Compression	Lossy or lossless	Lossy
Transparency	Yes	No
Animation	No	No
Introduced	1985	1992
Browser support	Browsers and Windows. Sizes are capped at 256×256.	Opens everywhere — every browser, OS and device.

ICO is stronger at: Holds multiple resolutions in one file. The format browsers expect for favicon.ico. Supports transparency.
JPG is stronger at: Opens on literally every device, browser and application ever made. Small files for photographic content. Adjustable quality, so you control the size/fidelity trade-off.

Why convert ICO to JPG?

People make this switch when they run into the limits of ICO: anything else. JPG is the better fit when you are sharing a photograph and compatibility matters more than squeezing out the last few kilobytes.

ICO limitations that prompt the switch: Capped at 256×256. Not a general-purpose image format. Awkward to edit.
What you give up: No transparency — there is no alpha channel at all. Visible artefacts around sharp edges and text.

Does converting ICO to JPG reduce quality?

ICO stores your data exactly; JPG does not. Some detail is discarded permanently in exchange for a much smaller file, which is usually the right trade for sharing and publishing. Keep your ICO original if it is the only copy — the conversion cannot be undone.

Saving a JPEG at 100% quality is still lossy — it is a large file that has been through the same discarding process, not a lossless copy.
