JP2 to SVG Converter
Convert JP2 to SVG in your browser. The JP2's pixels are traced into vector paths, so the result scales cleanly and can be edited in a vector app. You get an SVG traced into vector paths (or, if you prefer, the pixels embedded in an SVG wrapper). Nothing is uploaded.

How to use JP2 to SVG
- 1
Add your JP2 files: drop them here, choose them, or paste from the clipboard.
- 2
Choose how many colours to trace; fewer colours give simpler paths.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.
- 4
Download the .svg files one at a time or together as a ZIP.
Why use Aback Images for jp2 to svg
Where the SVG goes next
SVG opens in every browser, Illustrator, Inkscape, Figma and most design tools.
SVG next to JP2
A traced SVG describes every patch of colour as a path: logos and flat art stay compact, while photographs turn into very large markup.
The first lossy pass
The JP2 holds up to 16 bits per channel is common, more is possible 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.
JP2 vs SVG
What changes from JP2 to SVG
Encoding: the JP2 uses wavelet coding: reversible 5/3 for lossless files, irreversible 9/7 for lossy ones; SVG uses XML text describing paths, shapes and text, sometimes gzipped as .svgz, and the download is an SVG traced into vector paths (or, if you prefer, the pixels embedded in an SVG wrapper).
Bit depth: up to 16 bits per channel is common, more is possible in the JP2; SVG allows not fixed: coordinates and colours are continuous values, and the SVG written here has vector paths with flat colours. 12 and 16-bit JPEG 2000 files are reduced to 8 bits per channel.
Colour: sRGB, greyscale, YCC or a space described by an ICC profile in the JP2; SVG supports sRGB by default, other spaces through CSS colour functions, written here as flat colour regions.
Transparency: the JP2 stores it as an extra component flagged as opacity; the SVG keeps it as opacity on any element, with anti-aliased edges.
Metadata: the JP2 can carry XML, ICC and resolution boxes; SVG can carry title, description and RDF metadata elements, but nothing is copied across.
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.
JP2 files usually come from libraries and digital archives, medical (DICOM) and satellite imaging, and digital cinema packages.
About SVG
SVG describes shapes, paths and text as XML instead of pixels, so it stays crisp at any size. It is the standard for logos, icons and illustrations on the web.
An SVG is an XML document: a root <svg> element with a viewBox, then paths, shapes, text, gradients and filters. It can also embed raster images and, dangerously, scripts, which is why untrusted SVG is sanitized before rendering here.
When converting JP2 to SVG makes sense
SVG is the better choice for logos, icons and illustrations, while JP2 suits archival masters and specialist imaging.
SVG strengths: Infinitely scalable and sharp; Tiny files for logos and icons; Editable as text and styleable with CSS. Drawbacks to weigh: Not suitable for photographs; Can contain scripts, so untrusted SVG must be sanitized; Many apps and social sites will not accept it.
Limitations
- A JPEG 2000 file may be a lossless master or a lossy derivative; the file does not tell you which at a glance, so keep the original either way.
- Archival scans can be tens of thousands of pixels across, and decoding them needs a lot of memory on a phone.
- Tracing approximates the image with flat-colour shapes, so photographs become poster-like art rather than exact copies.
- Logos, icons and line art with clear edges trace best; raise the colour count for more detail.

Frequently asked questions
Does converting JP2 to SVG lose quality?
SVG is lossy, so detail the eye barely notices is discarded to save space. 12 and 16-bit JPEG 2000 files are reduced to 8 bits per channel.
Is transparency kept in the SVG?
Yes. JP2 stores it as an extra component flagged as opacity, and the SVG is written with an alpha channel, so transparent areas stay transparent.
Is the SVG a real vector or just embedded pixels?
By default the image is traced into true vector paths, so it scales without pixelation and can be edited in Illustrator, Figma or Inkscape. You can switch to embedding the pixels inside an SVG wrapper if you need an exact copy.
Which apps open SVG files?
Every browser, Illustrator, Inkscape, Figma and most design tools.
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.
