Methods & limits
Layout can be automated. The editorial choices remain yours.
The browser handles repeatable scaling, numbering, slicing, and export. It does not pretend to understand your photos.
Local processing
Images decode into Canvas in this browser without an upload endpoint. After refresh, the site cannot recover your files or layout.
Real size limits
Canvas capacity varies by device. Results scale proportionally when too long or pixel-heavy instead of promising unlimited lossless output and crashing.
Reviewable output
Contact sheets show numbers and filenames; nine-grid files stay 01–09; long images follow list order. The preview is the final composition.
