How do I convert ICO to SVG?

Add your ICO file to the upload area above, then press Convert. The SVG 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 SVG reduce quality?

The result is a reconstruction rather than a perfect copy. It is genuinely useful for reading and reuse, but review it before relying on it for anything important.

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 SVG 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.

SVG is not a picture of an image — it is XML describing shapes, paths and text. Because it stores instructions rather than pixels, it renders perfectly at any size, from a favicon to a billboard.

Where ICO files come from: Website favicons and Windows application icons.
Where SVG is used: Design tools like Figma and Illustrator, and icon libraries.

ICO vs SVG

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

ICO compared with SVG
Property	Source	Target
Compression	Lossy or lossless	None
Transparency	Yes	Yes
Animation	No	Yes
Introduced	1985	2001
Browser support	Browsers and Windows. Sizes are capped at 256×256.	All browsers and design tools.

ICO is stronger at: Holds multiple resolutions in one file. The format browsers expect for favicon.ico. Supports transparency.
SVG is stronger at: Infinitely scalable with no quality loss. Tiny files for logos and icons. Editable as text, and styleable with CSS.

Why convert ICO to SVG?

People make this switch when they run into the limits of ICO: anything else. SVG is the better fit when logos, icons, diagrams and anything that must stay sharp at every size.

ICO limitations that prompt the switch: Capped at 256×256. Not a general-purpose image format. Awkward to edit.
What you give up: Useless for photographs. Complex illustrations can be slower to render than a bitmap.

Does converting ICO to SVG reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

Converting a photo to SVG does not make it vector. It embeds the same bitmap inside an SVG wrapper — the file gets bigger and gains nothing.

About these formats

Source

Windows Icon

Multi-resolution icon container for favicons and apps.

Extensions: .ico
MIME type: image/x-icon
Best for: Favicons · Windows application icons
Compatibility: Browsers and Windows. Sizes are capped at 256×256.

Target

Scalable Vector Graphics

XML-based vector graphics that scale to any size.

Extensions: .svg
MIME type: image/svg+xml
Best for: Logos and icons · Illustrations · Infinite scaling
Compatibility: All browsers and design tools.

This embeds the picture inside an SVG wrapper at its original resolution. It does not trace the image into editable vector paths — nothing can do that faithfully for a photograph.
