EPS to JXL Converter

Convert EPS to JXL 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 JPEG XL encoded with libjxl compiled to WebAssembly, lossy at the quality you choose or lossless. Nothing is uploaded.

Why use Aback Images for eps to jxl

Where the JXL goes next

JXL opens in Safari 17+, macOS 14 and iOS 17, GIMP, Krita, ImageMagick and the libjxl tools.

JXL next to EPS

The JXL is built from the preview stored in the EPS, so its size follows that preview's resolution rather than the complexity of the artwork.

The first lossy pass

The EPS holds resolution-independent artwork, with previews usually 8-bit with nothing discarded yet. This conversion is the first lossy encode these pixels see, and hard edges and flat colour show it first.

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 JXL

What changes from EPS to JXL

Encoding: the EPS uses PostScript program text, with an optional binary TIFF preview or an EPSI hex preview; JXL uses lossy VarDCT or lossless modular coding; existing JPEGs can be repacked without loss, and the download is a JPEG XL encoded with libjxl compiled to WebAssembly, lossy at the quality you choose or lossless.

Bit depth: resolution-independent artwork, with previews usually 8-bit in the EPS; JXL allows 8 to 16 bits per channel, or floating point, and the JXL written here has 8 bits per channel.

Colour: CMYK, RGB and spot colours in the EPS; JXL supports sRGB, Display P3, linear and other spaces described in the codestream, written here as 8-bit sRGB.

Metadata: the EPS can carry DSC comments such as %%BoundingBox, %%Creator and %%Title; JXL can carry EXIF and XMP boxes in the container form, often stripped by encoders, 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 JXL

JPEG XL is a next-generation format designed to replace JPEG. It compresses better than JPEG and WebP, supports lossless, HDR and progressive decoding, and can losslessly repack existing JPEGs.

A JPEG XL file is either a bare codestream starting with FF 0A or an ISO base media container whose 'jxlc' box holds the codestream. A recompressed JPEG keeps a 'jbrd' box that lets the original JPEG bytes be rebuilt exactly.

When converting EPS to JXL makes sense

JXL is the better choice for archiving and future-proof high quality storage, while EPS suits print artwork and logos for professional layout software.

JXL strengths: Excellent lossy and lossless compression; Progressive decoding and HDR; Huge image sizes. Drawbacks to weigh: Browser support is limited (Safari only by default); Few apps can open it yet.

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.
  • Chrome and Firefox do not display JPEG XL by default, so it is not yet a format for websites; it suits archives and apps that support it.
  • Lossless JPEG XL is usually smaller than PNG for the same pixels.

Frequently asked questions

Does converting EPS to JXL lose quality?

JXL is lossy, so detail the eye barely notices is discarded to save space.

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.

Which apps open JXL files?

Safari 17+, macOS 14 and iOS 17, GIMP, Krita, ImageMagick and the libjxl tools. It opens in Safari 17 and later; Chrome and Firefox do not display it 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.
