How to batch process up to 16 images at once
The Bulk Image Processor is designed for uniform, high-volume output. This article walks through the workflow and the numbers you actually need to remember.
Drop up to 16 files
Click the Bulk Image Processor toggle, then drag up to 16 images onto the canvas or click to browse. Each file can be up to 100 MB, which means a single session handles up to 1.6 GB of concurrent processing. The cap is per-session, not per-day, so you can run as many sessions as you need back-to-back.
Pick a single target size
Unlike the Single Image Editor, the Bulk Image Processor applies one dimension to every image in the batch. Pick a platform preset or enter a custom dimension. Every image conforms to that size when you export. This is what makes Bulk useful for catalogs, galleries, and release-notes screenshots where consistency matters more than per-image polish.
Review the batch before export
Dropmatico shows a thumbnail grid of all 16 images. You can remove individual files from the batch, rename them, or drag to reorder. Use the common file name field to apply a single prefix to every file, or leave it blank to retain source filenames.
Export as a uniform ZIP
Click export and the Bulk Image Processor runs all 16 files in parallel on your machine. The output ZIP contains every image at the target size with consistent naming. No per-file custom sizes, no mixed dimensions, no leftover clutter. If you need different sizes across the same source files, run additional Bulk sessions back-to-back.
