EPS to ARW Converter
Convert EPS to ARW in your browser. You download a Linear DNG (.dng), not a .arw: only a Sony camera can create a genuine ARW, and every editor that opens ARW also opens DNG. Nothing is uploaded.

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.
- 4
Download the .dng files one at a time or together as a ZIP.
Why use Aback Images for eps to arw
Where a ARW would go
ARW files are opened by Sony Imaging Edge, Lightroom, Photoshop Camera Raw, Capture One and darktable, and every one of them opens the DNG too.
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 ARW
What changes from EPS to ARW
Encoding: the EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview; ARW uses Sony's lossy compressed raw, uncompressed (since the A7R II) or lossless compressed (since the A1), 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; ARW allows 12 or 14 bits per channel, and the DNG written here has 8 bits per channel, linearised.
Colour: CMYK, RGB and spot colours in the EPS; ARW supports camera RGB from a Bayer mosaic, written here as 8-bit sRGB.
Metadata: the EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title; ARW can carry EXIF, Sony maker notes, a thumbnail and a full-size JPEG, 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 ARW
ARW is the raw format of Sony Alpha, RX and Cyber-shot cameras. It stores the sensor data (compressed, uncompressed or lossless compressed, depending on the model) with a full-size JPEG preview.
ARW is TIFF-based: the first directory carries EXIF and Sony's JPEG preview and the sensor data sits in a sub-directory. In Sony's classic compressed raw each block of 16 same-colour pixels keeps an 11-bit maximum and minimum plus 7-bit steps for the rest, which can leave artefacts beside high-contrast edges.
ARW files come from Sony Alpha mirrorless and SLT cameras, RX compacts and some Cyber-shot models.
When converting EPS to ARW makes sense
Forms and workflows that ask for ARW usually feed a raw editor, and each of those opens DNG as well, so the DNG can take the ARW's place. Keep the EPS if you only need to view or share the picture.
What ARW offers when it comes straight from the camera: A full-size JPEG preview from the camera; Lossless compressed raw on recent bodies; Wide support across Sony's long Alpha line. Its drawbacks: Sony's classic compressed mode is lossy; Uncompressed files of 60 MB and more on high-resolution bodies; Creative Looks are ignored by most third-party raw editors.
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.

Frequently asked questions
Why do I get a .dng file instead of a .arw?
A real ARW is written by Sony cameras and holds the sensor's own readings (12 or 14 bits per channel, stored as Sony's lossy compressed raw, uncompressed (since the A7R II) or lossless compressed (since the A1)) along with EXIF, Sony maker notes, a thumbnail and a full-size JPEG. An EPS holds no sensor data, so no software outside the camera can create a genuine ARW. The Linear DNG you get instead is Adobe's open raw format, and every editor that opens ARW files opens it with the same raw controls. It holds decoded pixels, so it adds no quality or dynamic range.
Does converting EPS to ARW 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.
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.
