How many images can I process at once?

There is no hard limit set by the tool. Performance depends on your device — modern computers handle hundreds of images in a batch without issue. Processing happens entirely in your browser.

Can I apply different settings to different images in a batch?

Bulk tools apply the same settings to all images in the batch. For individual settings per image, process each image separately using the single-image tools.

How do I download all processed images?

After processing, click "Download All" to receive a ZIP file containing all the processed images. The filenames are preserved from the originals.
