Convert images to JPEG XL format (.jxl) with quality presets (lossless, visually lossless, or web). Use when you want optimal compression for photo archival or long-term storage, especially from JPEG originals where lossless transcoding preserves the original bitstream at smaller file size.

Batch-stamp copyright, artist, and rights information on all images in a directory. Use when you need to quickly add copyright metadata to a photo library before distribution or archival — a convenience wrapper around exiftool.
Decode JPEG XL images (.jxl) to PNG or JPEG. Use when you need to convert JXL files back to standard formats for compatibility, display, or further editing.
Extract embedded JPEG and PNG images from a PDF at their native resolution, without rasterizing. Use when a PDF is primarily a wrapper around photos or images and you want to recover them at full quality without the page rendering overhead.
Rasterize PDF pages to numbered image files (JPEG, PNG, or TIFF) at a specified resolution (DPI). Use when you need to convert PDF content to standalone images — one image per page — with optional page range selection.
Read and display EXIF, IPTC, XMP, and other metadata from images as structured JSON. Use when you need to inspect image metadata without modifying it — opposite of scrub-metadata, which removes metadata.
Write EXIF, IPTC, and XMP metadata tags to image files. Use when you need to add or update metadata like artist name, copyright, description, keywords, or GPS coordinates on individual images.

Encode images to JPEG XL (.jxl) format using cjxl. Supports lossless, visually lossless, and web quality presets, with optional effort (compression) tuning.
lossless (full fidelity, -d 0), visually-lossless (imperceptible loss, -d 1.0, default), or web (visible compression acceptable, -d 3.0). Default: visually-lossless.command -v cjxl || echo "cjxl not installed — install with: sudo apt install libjxl-tools"
Abort if missing.

find to locate all images in the tree.Ask for confirmation before batch operations.
Single file:
cjxl -d <distance> -e <effort> input.jpg output.jxl
Batch (folder or recursive):
find <target> -maxdepth <1|999> -type f \
\( -iname '*.jpg' -o -iname '*.jpeg' -o -iname '*.png' \
-o -iname '*.gif' -o -iname '*.webp' -o -iname '*.tif' \) \
-exec cjxl -d <distance> -e <effort> {} {.}.jxl \;
Show progress (file count, time remaining estimate if batch is large).
After conversion:
.jxl files created in the same directory as originals (or in a user-specified output folder).cjxl auto-detects JPEG bitstream and preserves it. To recover the original JPEG bit-exact later, use djxl --jpeg input.jxl recovered.jpg. This is the killer feature for photo archives.apt install libjxl-tools.
