A JP2 file is a still image, but some video editors and web platforms require a video file such as WEBM. Converting it makes a clip that displays the image for a chosen duration; it does not add motion.

What the JP2 format is

JP2 is the JPEG 2000 image format, used for scanned, archival, scientific, and other high-resolution images. Image editors and JPEG 2000 tools such as Adobe Photoshop and OpenJPEG can create or export JP2 files, so they may appear when images are moved between imaging workflows.

What the WEBM format is

WEBM is a video container commonly used for web playback. It can contain VP8, VP9, or AV1 video, and is useful when a site or editing workflow accepts video but not still-image formats. A JP2-to-WEBM conversion encodes the image as video frames; it does not create audio.

How to convert JP2 to WEBM

Online on 101convert.com

Open the JP2-to-WEBM converter on 101convert.com and upload the image files. The page supports batch conversion, subject to the per-file size limit shown there.
Before converting, set Show each picture for to choose how long each picture appears.
Start the conversion, then download the WEBM file or files.

Offline with desktop software

FFmpeg is free and runs on Windows, macOS, and Linux. With an FFmpeg build that includes JPEG 2000 decoding and the libvpx VP9 encoder, run this command to create a five-second clip at 25 frames per second:

ffmpeg -loop 1 -framerate 25 -i input.jp2 -t 5 -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2,format=yuv420p" -c:v libvpx-vp9 output.webm

Replace input.jp2 and output.webm with the actual filenames. Change -t 5 to the desired duration in seconds. If FFmpeg reports that the encoder or input format is unavailable, use a build with libvpx and JPEG 2000 support.

Quality and compatibility

The output repeats one still image for the selected duration. VP9 encoding with yuv420p converts the source to common 8-bit 4:2:0 video color, so fine color detail, transparency, or lossless JP2 quality may not be preserved. The scaling filter makes odd image dimensions even, as required by many 4:2:0 playback workflows.
