Frequently asked questions
Are my images uploaded anywhere?⌄
No — every step (resizing, format conversion, watermarking, ZIP packaging) runs entirely in your browser using the Canvas API. Nothing you add is ever sent to a server.
Can I run just one step, like only converting format without resizing?⌄
Yes — each step (resize, convert, watermark) has its own on/off switch. Turn off the ones you don't need; only the enabled steps run.
Is there a limit on how many images or how large they can be?⌄
Up to 200 images per batch, 30 MB each — generous enough for real batches (a folder of product photos, a course's worth of screenshots) while keeping everything fast and stable in the browser tab.
