EPS to DNG Converter
Convert EPS to DNG 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 Linear DNG: demosaiced 8-bit RGB with the colour matrices raw editors need. Nothing is uploaded.

Add your EPS files: drop them here, choose them, or paste from the clipboard.
- 2
There is nothing to tune: the DNG is written uncompressed. Resizing and rotating are under More options if you need them.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.

Download the .dng files one at a time or together as a ZIP.
Why use Aback Images for eps to dng
Where the DNG goes next
DNG opens in Lightroom, Photoshop Camera Raw, Capture One, darktable, RawTherapee, Affinity Photo and macOS Photos.
DNG next to EPS
The DNG 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 DNG is written uncompressed, 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 DNG
What changes from EPS to DNG
Encoding: the EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview; DNG uses lossless (or lossy) JPEG-compressed sensor data, plus optional JPEG previews, and the download is a Linear DNG: demosaiced 8-bit RGB with the colour matrices raw editors need.
Bit depth: resolution-independent artwork, with previews usually 8-bit in the EPS; DNG allows 8 to 16 bits per channel, and the DNG written here has 8 bits per channel, linearised.
Colour: CMYK, RGB and spot colours in the EPS; DNG supports camera RGB plus the colour matrices that map it to XYZ (demosaiced linear RGB in a Linear DNG), written here as 8-bit sRGB.
Metadata: the EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title; DNG can carry EXIF, XMP and DNG tags for colour matrices, calibration and lens corrections, 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 DNG
DNG is Adobe's openly documented raw format. Some cameras and phones record it directly, Adobe DNG Converter turns other brands' raw files into it, and a Linear DNG holds already-demosaiced RGB that raw editors treat like any other raw file.
DNG is built on TIFF/EP. The raw image sits in a sub-IFD marked as the main image, with tags for black and white levels, colour matrices and the colour filter pattern; a Linear DNG (PhotometricInterpretation 34892) stores demosaiced RGB instead of a mosaic. Previews are optional, and Adobe DNG Converter can write a medium (1024 px), full-size or no preview.
When converting EPS to DNG makes sense
DNG is the better choice for raw editing and archiving raw files in an open format, while EPS suits print artwork and logos for professional layout software.
DNG strengths: Open specification read by every raw editor; Lossless compression and optional previews; Recorded directly by Leica, Pentax, DJI drones and phones. Drawbacks to weigh: Large files; No browser or ordinary photo viewer support on every platform.
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.
- The DNG holds the decoded 8-bit pixels, so it adds no dynamic range or detail beyond the EPS.
- Raw editors apply their own default profile and tone curve to a DNG, so it can look slightly different from the source until you adjust it.
- A Linear DNG has no sensor mosaic, so demosaicing settings in your raw editor have no effect on it.

Frequently asked questions
Does converting EPS to DNG lose quality?
DNG is written uncompressed, 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.
Can Lightroom edit this DNG like a camera raw file?
It opens with the full raw controls in Lightroom, Photoshop Camera Raw, Capture One and darktable, because it is a valid Linear DNG. It holds the decoded 8-bit pixels, though, so it has no more dynamic range or detail than the image it came from.
Which apps open DNG files?
Lightroom, Photoshop Camera Raw, Capture One, darktable, RawTherapee, Affinity Photo and macOS Photos. 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.
