Applies to lossy formats: JPEG, WebP, AVIF, HEIC, JPEG XL.

Aspect ratio is preserved. Leave blank to keep the original size.

Automatic tries ImageMagick first and falls back to GD if it cannot handle the pair.

    Files are converted on our server and deleted automatically after 60 minutes.

    Why convert X3F to JPEG 2000?

    • JPEG 2000 supports transparency, so background-free areas of your X3F images survive the conversion.
    • Conversion happens on demand and the result is deleted automatically, so nothing lingers.

    How to convert X3F to JPEG 2000

    1. 1

      Upload your X3F files

      Drag up to 10 files onto the drop zone, or click to browse. The format is verified from the file content.

    2. 2

      Confirm the target format

      JPEG 2000 is already preselected. Adjust quality with the slider, and set a maximum width or height if the files are too large.

    3. 3

      Start the conversion

      Press Convert now. Each file is processed on the server and appears in the result list with its new size and dimensions.

    4. 4

      Download the results

      Save files one by one, or use Download all to grab the whole batch. Links stay valid for a limited time.

    Questions about converting X3F to JPEG 2000

    Is converting X3F to JPEG 2000 free?

    Yes, completely free and without sign-up. There is a per-file size cap for server stability, but no daily quota.

    How long does X3F to JPEG 2000 conversion take?

    Typically under a second per image. Large photos, RAW files and multi-page documents take longer because they must be fully decoded first.

    Which engine handles X3F to JPEG 2000?

    This pair is processed by IMAGEMAGICK. If you explicitly pick the other engine and it cannot handle the pair, the converter automatically falls back to the one that can.

    Does the JPEG 2000 output keep transparency?

    Transparency support in JPEG 2000: Yes. When it is not available, transparent areas are composited onto the background colour you choose, white by default.

    Does converting X3F to JPEG 2000 keep animation?

    JPEG 2000 animation support: Yes. When frames cannot be preserved, only the first frame is written.

    Are my X3F files deleted?

    Yes. Both the upload and the converted output are deleted automatically after 60 minutes, and you can rely on the fact that access requires an unguessable random token.

    About this conversion

    X3F and JPEG 2000 are both well-established image formats, but they were designed for different jobs. Knowing which one wins in which situation saves you both storage and headaches.

    On this server the pair is handled by IMAGICK, which decodes the source fully before writing the target. That matters for two reasons: colour profiles are applied consistently, and metadata such as EXIF orientation is baked into the pixels so the result is upright everywhere.

    If you need to go back the other way, the reverse conversion is available on its own page — and if you are unsure which format suits your use case, the format guides explain the trade-offs in plain language.
