Package 2 to 50 signature-checked images into an organised ZIP with safe names and a formula-protected CSV manifest.
Processed in this browser2 to 50 PNG, JPEG, WebP, or GIF files; 10 MB per image and 100 MB total. Image bytes are not decoded or recompressed.
2-50 images - 100 MB total
No file upload
This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.
Original stays unchanged
The converter creates a separately named output. It never writes back into the source file.
Bounded work

Plain-language method
How the image handoff is organised
Nirmion verifies that each extension agrees with a supported image signature, copies the exact bytes into an images folder, assigns collision-safe names, and records source name, archive path, byte size, and browser MIME in manifest.csv.
- 01Choose a valid source
Choose only images you own or are authorised to distribute. Damaged files and renamed non-images are rejected before packaging.
- 02Review the conversion choices
Use numbered for ordered delivery or preserve when familiar source names matter. The archive name is cleaned for broad filesystem compatibility.
- 03Inspect the separate result
The ZIP contains images/ plus a UTF-8 manifest.csv. Checksums of the image bytes remain the same after extraction.
Useful when
Practical jobs this tool handles
- Deliver approved campaign images with a manifest.
- Bundle product photos in a numbered review order.
- Archive original image files without quality loss.
Before converting
Make the handoff useful
- Put files in the intended browser selection order.
- Choose whether recipients need source names or sequence names.
- Check rights, sensitive metadata, and archive contents before sending.
Know the boundary
Metadata and file contents remain intact
Because originals are byte-identical, EXIF location, author data, animation frames, and other embedded metadata are not removed. Use a metadata-removal tool first when privacy requires it.
Quick answers
Questions before you convert
Packaging preserves originals rather than optimising them.
Are images recompressed?
No. The original bytes are copied into the ZIP.
How are duplicate names handled?
A numeric suffix is added so no selected image silently replaces another.
What is in the manifest?
It maps each source filename to its archive path, size, and browser-reported MIME type.
