FAQ
Frequently asked questions
Why do sites ask for images under 1 MB?
1 MB is a common cap on job sites, marketplaces, forums and email services. It keeps uploads fast while still allowing sharp photos.
Is 1 MB the same as 1000 KB?
We use 1 MB = 1024 KB, which matches Windows and most upload forms. A file shown as 0.98 MB here is under the limit.
Will it reduce quality noticeably?
Rarely. Most photos come out at 85–92% quality, which looks identical to the original on screen.
Can I pick a different size?
Yes — type any size or tap a quick target like 500 KB; the images update automatically.
