BMP to EPS Converter
Convert BMP to EPS in your browser. BMP files usually come from Windows Paint, legacy Windows programs, embedded displays and some scanners; EPS is the better fit for print artwork and logos for professional layout software. You get an EPS that wraps the pixels as a PostScript image; it contains no vector paths. Nothing is uploaded.

How to use BMP to EPS
- 1
Add your BMP files: drop them here, choose them, or paste from the clipboard.
- 2
Pick the colour that replaces transparent areas, since EPS has none.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.
- 4
Download the .eps files one at a time or together as a ZIP.
Why use Aback Images for bmp to eps
Where the EPS goes next
EPS opens in Illustrator, CorelDRAW, InDesign, Affinity Designer, Ghostscript, and Inkscape through Ghostscript.
EPS next to BMP
The EPS is written uncompressed, so expect it to be several times larger than the BMP, which stores usually none; RLE for some 4 and 8-bit files.
Written without a lossy pass
The EPS is written uncompressed, so the pixels decoded from the BMP 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.
BMP vs EPS
What changes from BMP to EPS
Encoding: the BMP uses usually none; RLE for some 4 and 8-bit files; 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, 4, 8, 16, 24 or 32 bits per pixel in the BMP; EPS allows resolution-independent artwork, with previews usually 8-bit, and the EPS written here has 8 bits per channel.
Colour: RGB or an indexed palette in the BMP; EPS supports CMYK, RGB and spot colours, written here as 8-bit sRGB.
Transparency: the BMP stores it as an optional fourth byte in 32-bit files, which many programs ignore; the EPS has none, so transparent areas are filled with the colour you choose.
Metadata: the BMP can carry nothing beyond the header's resolution fields (and a colour profile in rare V5 headers); EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title, but nothing is copied across.
About BMP
BMP stores raw, uncompressed pixels. Files are huge but trivially simple, which is why some legacy Windows software, embedded displays and printers still ask for it.
A BMP is a 14-byte file header ('BM' and the offset to the pixels), a DIB header (40 bytes, or 108 and 124 bytes in the V4 and V5 versions that add colour masks and alpha), an optional palette, then pixel rows padded to 4 bytes and normally stored bottom-up.
BMP files usually come from Windows Paint, legacy Windows programs, embedded displays and some scanners.
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 BMP to EPS makes sense
EPS is the better choice for print artwork and logos for professional layout software, while BMP suits legacy software and embedded systems that require it.
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
- BMP stores nearly every pixel literally, so almost any compressed target is several times smaller.
- A 32-bit BMP can carry an alpha byte that most programs ignore; if the image suddenly gains transparent areas after converting, that byte was set.
- 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 BMP to EPS lose quality?
EPS is written uncompressed, so the pixels are stored exactly as decoded.
What happens to transparency when converting BMP to EPS?
BMP stores transparency as an optional fourth byte in 32-bit files, which many programs ignore. 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.
