JPEG 2000 to GIF Converter

Convert JPEG 2000 files to GIF. Batch, free and without uploading.

This tool converts JPEG 2000 files to GIF. JPEG 2000 is used in archives, digital cinema and medical imaging.

GIF is an old format limited to 256 colours. It is still used for simple animations and graphics with few colours; photos lose colour quality. GIF is lossless, so nothing is lost from the image during conversion.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your JPEG 2000 files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Optionally set a maximum width and height.
3. Press "Convert" and download the GIF files one by one or as a ZIP.

Frequently asked questions

Will converting to GIF reduce quality?

No. GIF is lossless; the image in your JPEG 2000 is carried over as it is.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

No. Your JPEG 2000 files are converted to GIF inside your browser and never sent to a server.
