Frequently Asked Questions
Everything you need to know about Batch Multi-Resizer.
How many images can I resize in bulk at one time?
OmniTools lets you upload up to 15 photos per batch. Once configured, they are all processed simultaneously.
Can I set a target file size like 50KB for all bulk images?
Yes. Enable 'Target Max File Size' and set your target KB (e.g. 50KB). Every image in your queue will be compressed under that limit during batch export.
