EPS to CR2 Converter
Convert EPS to CR2 in your browser. You download a Linear DNG (.dng), not a .cr2: only a Canon camera can create a genuine CR2, and every editor that opens CR2 also opens DNG. Nothing is uploaded.

Why use Aback Images for eps to cr2
Where a CR2 would go
CR2 files are opened by Canon Digital Photo Professional, 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 CR2
What changes from EPS to CR2
Encoding: the EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview; CR2 uses lossless JPEG-compressed sensor data, cut into vertical slices, 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; CR2 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; CR2 supports camera RGB from a Bayer mosaic, with the Picture Style recorded in the maker notes, written here as 8-bit sRGB.
Metadata: the EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title; CR2 can carry EXIF, Canon maker notes (Picture Style, lens, focus points) and the embedded previews, 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 CR2
CR2 is the raw format of Canon EOS cameras from 2004 until CR3 replaced it in 2018. It holds the sensor's 12 or 14-bit readings, losslessly compressed, plus a large JPEG preview rendered with the camera's Picture Style.
CR2 is TIFF-based: the TIFF header is followed by the letters 'CR' and version 2.0, then four image directories: a large JPEG preview with the EXIF block, a 160×120 thumbnail, a small uncompressed RGB image, and the sensor data as lossless JPEG cut into vertical slices.
CR2 files come from Canon EOS DSLRs made from 2004 to 2018, such as the 5D Mark II and III, 6D, 7D and the Rebel series.
When converting EPS to CR2 makes sense
Forms and workflows that ask for CR2 usually feed a raw editor, and each of those opens DNG as well, so the DNG can take the CR2's place. Keep the EPS if you only need to view or share the picture.
What CR2 offers when it comes straight from the camera: Large embedded JPEG rendered with the camera's Picture Style; Lossless 12 or 14-bit sensor data; Widely supported after fourteen years of Canon DSLRs. Its drawbacks: Replaced by CR3 in 2018, so current Canon bodies no longer write it; 20 to 50 MB per photo; Sliced lossless JPEG data that only raw decoders can read.
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 .cr2?
A real CR2 is written by Canon cameras and holds the sensor's own readings (12 or 14 bits per channel, stored as lossless JPEG-compressed sensor data, cut into vertical slices) along with EXIF, Canon maker notes (Picture Style, lens, focus points) and the embedded previews. An EPS holds no sensor data, so no software outside the camera can create a genuine CR2. The Linear DNG you get instead is Adobe's open raw format, and every editor that opens CR2 files opens it with the same raw controls. It holds decoded pixels, so it adds no quality or dynamic range.
Does converting EPS to CR2 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.
