Frequently asked questions
How many bytes is 20 KB?
This tool counts 20 KB as 20,000 bytes (0.02 MB). Sites that use 1 KB = 1,024 bytes allow 20,480 bytes, so a file made here always fits.
How large will my photo be at 20 KB?
Two 3,840×2,160 px photos came out at 504×283 px and 483×272 px. Simple backgrounds keep more pixels.
Will the image look bad at 20 KB?
Automatic resizing keeps JPG quality at 60% or higher and lowers the dimensions instead, so you get a smaller but clean photo rather than blocky artifacts.
Does it work on a phone?
Yes. Open this page in your phone browser and pick photos from your gallery. iPhone HEIC photos are converted to JPG.
