EPS to JP2 Converter
Convert EPS to JP2 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 lossless JPEG 2000 (.jp2) using the reversible 5/3 wavelet. Nothing is uploaded.

Download the .jp2 files one at a time or together as a ZIP.
Why use Aback Images for eps to jp2
Where the JP2 goes next
JP2 opens in macOS Preview, GIMP, IrfanView, XnView, ImageMagick and the OpenJPEG tools.
JP2 next to EPS
The JP2 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 JP2 is written losslessly, 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 JP2
What changes from EPS to JP2
Encoding: the EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview; JP2 uses wavelet coding: reversible 5/3 for lossless files, irreversible 9/7 for lossy ones, and the download is a lossless JPEG 2000 (.jp2) using the reversible 5/3 wavelet.
Bit depth: resolution-independent artwork, with previews usually 8-bit in the EPS; JP2 allows up to 16 bits per channel is common, more is possible, and the JP2 written here has 8 bits per channel.
Colour: CMYK, RGB and spot colours in the EPS; JP2 supports sRGB, greyscale, YCC or a space described by an ICC profile, written here as 8-bit sRGB.
Metadata: the EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title; JP2 can carry XML, ICC and resolution boxes, 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 JP2
JPEG 2000 is a wavelet-based format that can be truly lossless or lossy, handles very high bit depths and huge images, and is used where long-term fidelity matters: archives, medicine, satellites and digital cinema.
A .jp2 file is a box structure: a 12-byte signature box, an 'ftyp' box, a 'jp2h' header box with the size and colour specification, then the 'jp2c' box holding the codestream, which begins with FF 4F FF 51.
When converting EPS to JP2 makes sense
JP2 is the better choice for archival masters and specialist imaging, while EPS suits print artwork and logos for professional layout software.
JP2 strengths: True lossless mode; High bit depths and very large images; Standardised for archives and digital cinema. Drawbacks to weigh: Browsers do not display it; Slow to encode and decode; Patchy support in everyday apps.
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.
- Lossless JPEG 2000 is larger than a lossy one, but usually smaller than an uncompressed TIFF of the same pixels.
- No current browser displays JP2 by default; archive and imaging software opens it.

Frequently asked questions
Does converting EPS to JP2 lose quality?
JP2 is written losslessly, 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.
Is the JPEG 2000 file lossless?
Yes. It is written with JPEG 2000's reversible 5/3 wavelet, so decoding it gives back exactly the pixels that went in. The trade-off is size: a lossless JP2 is larger than a lossy one, though usually smaller than an uncompressed TIFF.
Which apps open JP2 files?
MacOS Preview, GIMP, IrfanView, XnView, ImageMagick and the OpenJPEG tools. It does not open in web browsers by default.
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.
