Top 5 SVG to ICO Converters Every Developer Should Know

If you’ve ever shipped a website, browser extension, or desktop app, you’ve probably run into this:

“My logo is an SVG… but I need a proper ICO file.”

SVG is perfect for design.

ICO is still required for favicons, Windows apps, and some legacy systems.

I tested a handful of SVG to ICO converters and ranked them based on what actually matters to developers:

speed, simplicity, and correct output.

1. svg-to-ico.org — Clean, Practical, and Developer-First ⭐⭐⭐⭐⭐

👉 https://svg-to-ico.org

This is the one I keep coming back to.

It’s not just a converter — it feels like a small toolbox for getting icons right.

Why it stands out

  • One-click recolor

    Quickly adjust icon colors to match your brand, without opening a design tool.

  • Round corners & simple cropping

    Helps icons look polished and consistent across browsers and operating systems.

  • Smart preview

    See how your icon looks in real places — like browser tabs or app shortcuts — before exporting.

  • All-in-one favicon package

    Generates everything you need in one go, instead of making each size manually.

About icon size (yes, 256×256 matters)

The tool includes 256×256 icons, which is important because:

  • High-DPI screens need larger source icons to stay sharp
  • Windows 10/11 uses 256×256 as a standard size
  • macOS scales icons better from high-resolution sources
  • Web apps and PWAs rely on larger icons for install prompts

Why it’s #1

No accounts.

No distractions.

No guessing.

You upload an SVG and get an ICO that actually works everywhere.

Best for:

Favicons, Windows apps, PWAs, and everyday development work.

2. ConvertICO — Solid for Multi-Size ICO Files ⭐⭐⭐⭐

ConvertICO is a long-standing option and still does its job well.

Pros

  • Supports multiple icon sizes in one ICO
  • Simple workflow
  • Good Windows compatibility

Cons

  • File size limits
  • Interface feels dated

Still a good choice if your main goal is multi-resolution ICO output.

3. MiConv — Fast, Cloud-Based Conversion ⭐⭐⭐

MiConv focuses on speed and simplicity.

Pros

  • Very fast
  • Easy to use
  • Handles large files

Cons

  • Files are uploaded to a server
  • Minimal control over output

Good for quick tasks when customization isn’t important.

4. ImageTool SVG to ICO — More Options, Less Focus ⭐⭐⭐

This tool offers many image utilities, including SVG to ICO.

Pros

  • Batch support
  • Adjustable size and background
  • Runs in the browser

Cons

  • Busy interface
  • Not tailored specifically for developers

Useful, but not as focused as svg-to-ico.org.

5. QuillBot SVG to ICO Converter — Simple but Basic ⭐⭐

A surprisingly clean tool, but very minimal.

Pros

  • Easy to use
  • No setup
  • Clean interface

Cons

  • Limited control
  • Not ideal for production assets

Works fine for one-off conversions.

Quick Comparison

Tool Ease of Use Control Dev-Friendly
svg-to-ico.org ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐⭐
ConvertICO ⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐
MiConv ⭐⭐⭐⭐ ⭐⭐ ⭐⭐⭐
ImageTool ⭐⭐⭐ ⭐⭐⭐ ⭐⭐⭐
QuillBot ⭐⭐⭐ ⭐⭐ ⭐⭐

Final Thoughts

Most SVG to ICO converters work.

But svg-to-ico.org feels like it was built by someone who’s actually shipping software:

  • quick tweaks
  • real previews
  • correct sizes
  • no friction

If you just want an ICO file that looks right everywhere —

this is the easiest recommendation.
