EPS to ICO Converter
Convert EPS to ICO in your browser. The converter uses the preview image saved inside the EPS, not its vector artwork, because no browser can run PostScript. You get a multi-size ICO with PNG-compressed icons (16, 32, 48 and 256 px by default). Nothing is uploaded.

Why use Aback Images for eps to ico
Where the ICO goes next
ICO opens in every browser (as a favicon), Windows and most Linux desktops.
ICO next to EPS
The ICO is built from the preview stored in the EPS, so its size follows that preview's resolution rather than the complexity of the artwork.
Written without a lossy pass
The ICO is written losslessly, so the pixels decoded from the EPS arrive unchanged.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
EPS vs ICO
What changes from EPS to ICO
Encoding: the EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview; ICO uses each size stored as a headerless BMP or as a complete PNG, and the download is a multi-size ICO with PNG-compressed icons (16, 32, 48 and 256 px by default).
Bit depth: resolution-independent artwork, with previews usually 8-bit in the EPS; ICO allows 1 to 32 bits per pixel, set per size, and the ICO written here has 32 bits per pixel.
Colour: CMYK, RGB and spot colours in the EPS; ICO supports RGB or a palette, per image, written here as 8-bit sRGB.
Metadata: the EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title; ICO can carry only a directory of the sizes inside, with no EXIF, but nothing is copied across.
About EPS
EPS is a PostScript drawing packaged for placing inside other documents. It was the exchange format of print and logo design for decades; most EPS files also carry a raster preview so layout software can show them.
An EPS is a PostScript program with DSC comments ('%!PS-Adobe-3.0 EPSF-3.0', %%BoundingBox). Files from Illustrator, Photoshop and CorelDRAW usually start with a 30-byte binary header (C5 D0 D3 C6) that points to a TIFF preview; others carry an EPSI hex preview between %%BeginPreview and %%EndPreview.
EPS files usually come from Illustrator, CorelDRAW, InDesign, TeX figures and stock vector libraries.
About ICO
ICO is a container that bundles several sizes of the same icon (16, 32, 48, 256 px) into one file. It is still the most compatible format for website favicons and Windows app icons.
An ICO starts with a 6-byte ICONDIR (type 1 for icons) and a 16-byte entry per image giving width, height, colour count and offset. Each image is either a BMP without its file header plus an AND mask, or a complete PNG.
When converting EPS to ICO makes sense
ICO is the better choice for favicons and Windows icons, while EPS suits print artwork and logos for professional layout software.
ICO strengths: Multiple sizes in one file; Required by Windows and supported by every browser as a favicon. Drawbacks to weigh: Max 256×256 per image; Not for photos.
Limitations
- The preview image stored inside the EPS is converted, not the vector artwork, so the output resolution is whatever the preview was saved at, often screen resolution. Raster EPS files, an image wrapped in PostScript, are read at full resolution.
- An EPS with no embedded preview (Inkscape's default and hand-written PostScript, for example) cannot be converted here, because a browser cannot run PostScript.
- Each size inside the ICO is scaled from your image, and detailed artwork loses legibility at 16 and 32 px, so simplify logos first.
- Non-square images are centred on a transparent square for each icon size.

Frequently asked questions
Does converting EPS to ICO lose quality?
ICO is written losslessly, so the pixels are stored exactly as decoded.
Does this render the vector artwork in the EPS?
No. Browsers cannot run PostScript, so the converter uses the preview image that Illustrator, Photoshop, CorelDRAW and similar apps save inside the EPS, which is usually screen resolution. An EPS that simply wraps a raster image is read at full resolution. For full-resolution vector artwork, export from the original design app, or render the EPS with Ghostscript or Inkscape.
Which icon sizes are included?
16, 32, 48 and 256 px by default, the set Windows and browsers expect. You can choose other sizes. Non-square images are centred on a transparent square.
Which apps open ICO files?
Every browser (as a favicon), Windows and most Linux desktops.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
