Frequently Asked Questions
Which systems commonly require 500KB images?
Job application portals, e-commerce back-ends, school systems, and CMS uploads all use 500KB or similar ceilings to keep storage and load times manageable.
Can a product photo still look good at 500KB?
Yes. 500KB is generous enough for a clean product shot on a white background - most such photos compress well within it. The preview shows the final look before you download.
How fast can I process several images?
Each image takes seconds: upload, slide the quality control, and download. With the size preview, most images are done on the first pass.
