Why use Aback Images for ico to eps
Where the EPS goes next
EPS opens in Illustrator, CorelDRAW, InDesign, Affinity Designer, Ghostscript, and Inkscape through Ghostscript.
EPS next to ICO
The EPS is written uncompressed, so expect it to be several times larger than the ICO, which stores each size stored as a headerless BMP or as a complete PNG.
Written without a lossy pass
The EPS is written uncompressed, so the pixels decoded from the ICO 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.
ICO vs EPS
What changes from ICO to EPS
Encoding: the ICO uses each size stored as a headerless BMP or as a complete PNG; EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview, and the download is an EPS that wraps the pixels as a PostScript image; it contains no vector paths.
Bit depth: 1 to 32 bits per pixel, set per size in the ICO; EPS allows resolution-independent artwork, with previews usually 8-bit, and the EPS written here has 8 bits per channel.
Colour: RGB or a palette, per image in the ICO; EPS supports CMYK, RGB and spot colours, written here as 8-bit sRGB.
Transparency: the ICO stores it as 8-bit alpha in 32-bit and PNG entries, or a 1-bit mask in old icons; the EPS has none, so transparent areas are filled with the colour you choose.
Other images: the ICO can hold several sizes of the same picture, typically 16, 32, 48 and 256 px; only the main image is converted.
Metadata: the ICO can carry only a directory of the sizes inside, with no EXIF; EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title, but nothing is copied across.
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.
ICO files usually come from website favicons, Windows programs and installers.
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.
When converting ICO to EPS makes sense
EPS is the better choice for print artwork and logos for professional layout software, while ICO suits favicons and Windows icons.
EPS strengths: Vector artwork that prints at any size; Accepted by print shops and older layout software; CMYK and spot colours. Drawbacks to weigh: Browsers and phones cannot display it; Needs a PostScript interpreter to render the vector data; Superseded by PDF and SVG.
Limitations
- The largest image in the icon is the one converted; smaller sizes that were hand-tuned for 16 px are not carried over.
- The EPS holds pixels inside a PostScript wrapper, so it prints at the resolution of your image and will not get sharper when enlarged.
- Transparency is flattened onto the background colour, because the EPS image has no alpha channel.

Frequently asked questions
Does converting ICO to EPS lose quality?
EPS is written uncompressed, so the pixels are stored exactly as decoded. Not carried over: any several sizes of the same picture.
What happens to transparency when converting ICO to EPS?
ICO stores transparency as 8-bit alpha in 32-bit and PNG entries, or a 1-bit mask in old icons. EPS has no alpha channel, so transparent pixels are composited onto a solid colour, white unless you pick another. To keep transparency, convert to PNG, WebP or AVIF instead.
Is the EPS a vector file?
No. The EPS wraps the pixels as a PostScript image, which is what layout and print software need to place it, but it has no vector paths, so it does not get sharper when enlarged. For real vectors, trace the image to SVG first.
Which apps open EPS files?
Illustrator, CorelDRAW, InDesign, Affinity Designer, Ghostscript, and Inkscape through Ghostscript. It does not open in web browsers.
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.
