SVG to ICO Converter

Convert an SVG into a Windows ICO icon with 16, 32, 48 and 256 pixel versions inside. Of every conversion on this site, this is the one where the source format is exactly right for the job: each size is drawn from your original shapes rather than shrunk from a bitmap.

How to convert SVG to ICO in 3 steps

Format comparison

SVG vs ICO

SVG (Scalable Vector Graphics)

Vector

Describes shapes and text as instructions rather than pixels, so it can be drawn sharply at any size.

  • Crisp at any size, from favicon to billboard
  • Very small files for logos, icons and diagrams
  • Cannot represent a photograph, and many apps cannot import it

ICO (Windows Icon)

Multi-size icon

Bundles several sizes of the same small image in one file, for Windows icons and website favicons.

  • Several icon sizes in a single file
  • Understood by every browser as a favicon
  • Only for small images — each entry is at most 256 × 256 pixels

Why a vector source is genuinely better here

Every other route to an icon starts with a bitmap and shrinks it. Shrinking averages pixels together, and at the sizes icons live at — 16 and 32 pixels — that averaging is brutal. A crisp one-pixel line in a 256-pixel image becomes a faint grey suggestion at 16.

An SVG is not pixels; it is instructions. So the 16-pixel entry is drawn at 16 pixels, with the renderer deciding how to place edges at that scale, rather than being derived from a larger picture. Lines land on whole pixels, shapes stay closed, and contrast survives.

The difference is clearly visible on a browser tab, and it is why designers keep icons as vectors and export bitmaps last.

Transparency is preserved properly

SVG artwork is almost always drawn on transparency, and that carries straight through. Where your artwork does not cover, the icon is genuinely transparent — so it sits correctly on a light tab, a dark tab, a coloured taskbar, or anything else.

Non-square artwork is centred on a square canvas with transparent padding rather than being stretched, so proportions are kept and no background is introduced.

What still needs care

Detail that is invisible at 16 pixels is worse than useless — it turns into noise that muddies the shape. If your logo has fine strokes, small text or a thin outline, they will not read, however well they are rendered.

Professional icon sets solve this by drawing separate simplified artwork for small sizes: fewer elements, thicker strokes, sometimes just an initial. If your icon matters, that is worth doing — export a simplified SVG, make an ICO from it, and use it for the small sizes.

Fonts are a trap. If your SVG names a font instead of embedding the letter shapes, the renderer substitutes whatever it has and your wordmark may come out in something else entirely. Convert text to outlines in your editor before exporting.

Quality

Quality and file size

There is no quality setting. Each size is rendered from the vector and stored losslessly, which is the best result available from any source.

Design rules that actually matter at 16 pixels

  • One idea. A mark, a letter, a silhouette. Not a scene, not a wordmark, not a logo with a tagline.
  • Strokes no thinner than about 1/16 of the width. Anything finer disappears at the smallest size.
  • Strong contrast against both light and dark. Browser tabs come in both, and an icon that vanishes on one of them is failing half the time.
  • Leave a little breathing room — art that runs to the very edge looks cramped beside other tabs.

Test it small, on both themes

Look at the 16-pixel version at actual size against white and against near-black. Most icon problems are invisible at any other size and obvious at that one.

For a website, get the whole set

An ICO alone has not been enough for years. The favicon generator takes the same SVG and produces the full modern set — the ICO plus the PNG sizes Apple and Android look for, and the manifest entries — which is what a site actually needs.

Is uploading an SVG safe?

A reasonable question, because SVG is the one image format that is really a program: it can contain scripts and references to external resources.

Every SVG is screened before anything parses it. Files declaring document types or entities, containing scripts, or referencing external resources are refused outright rather than sanitised, and the renderer separately ignores external references. Because the output is a rendered bitmap, nothing from your file could ever execute anywhere.

Where to put the file

Name it favicon.ico and put it at the root of your site — /favicon.ico — not in an assets folder. Browsers request that exact path without being told to, and so do feed readers, chat apps building link previews, and bookmark managers.

You can additionally declare it in your HTML, but the root file is what catches every client that does not read your markup first.

Why not just use an SVG favicon?

You can, and modern browsers support it — <link rel="icon" href="/icon.svg"> works in Chrome, Firefox and Safari, and it stays sharp at any size, including on displays that do not exist yet.

What it does not cover is everything that is not a modern browser: Windows shortcuts, installers, older clients, and the automatic /favicon.ico request. The usual answer is both — an SVG icon declared in HTML, and an ICO at the root as the fallback. This tool makes the second from the first.

Recovering artwork from an old icon

Going the other way, ICO to PNG extracts the largest image from an existing icon. That will give you a bitmap, not vectors — an ICO contains no shape information to recover — but it is often enough to redraw from.

What happens to your file

Browsers cannot write the ICO container, so this runs on our server. Your upload is deleted the moment conversion finishes, the result is deleted as you download it, and anything abandoned is swept automatically.

Privacy

What happens to your file

This tool runs on our server, so it works the same on every phone and computer. Your file is uploaded, and this is exactly what happens to it:

  • Stored outside the public web root under a random name, never under your file's name.
  • Processed, with the original upload deleted immediately — whether it succeeded or failed.
  • The result sits behind a signed link that only you receive, which stops working after 20 minutes, and the file is deleted the moment you download it.
  • Anything never collected is deleted automatically within 30 minutes.
  • The image itself is never logged or kept. If a conversion fails, we record the formats involved and the error — not the file.
  • Camera metadata, including any GPS coordinates recording where a photo was taken, is removed from the result. Only the rotation needed to show the image the right way up is kept.

Questions & answers

SVG to ICO: frequently asked questions

Why is an SVG a better icon source than a PNG?

Because each size is drawn from your original shapes rather than shrunk from a bitmap. Shrinking averages pixels together, and at 16 pixels that is brutal — a crisp one-pixel line in a 256-pixel image becomes a faint grey suggestion. Rendering at 16 lets edges land on whole pixels and keeps contrast intact. The difference is visible on a browser tab.

Is transparency preserved?

Yes, properly. SVG artwork is nearly always drawn on transparency and that carries through, so the icon sits correctly on a light tab, a dark tab or a coloured taskbar. Non-square artwork is centred with transparent padding rather than stretched.

My logo has fine detail. Will it work?

Probably not at 16 pixels, however well it is rendered — fine strokes and small text become noise that muddies the shape. Professional icon sets draw separate simplified artwork for small sizes: fewer elements, thicker strokes, sometimes just an initial. If the icon matters, export a simplified SVG and make the small sizes from that.

My text came out in the wrong font.

Your SVG names a font rather than embedding the letter shapes, so the renderer substituted what it had. Convert text to outlines in your editor before exporting — worth doing for any artwork that leaves your machine.

Can I just use an SVG favicon instead?

Partly. Modern browsers support <link rel="icon" href="/icon.svg"> and it stays sharp at any size. It does not cover Windows shortcuts, installers, older clients, or the automatic /favicon.ico request browsers make on their own. The usual answer is both — an SVG declared in HTML and an ICO at the root.

Is uploading an SVG safe?

Every SVG is screened before anything parses it: files with document type declarations, entities, scripts or external references are refused rather than sanitised, and the renderer separately ignores external references. Since the output is a rendered bitmap, nothing from your file could execute anywhere.
