Frequently asked questions

How many bytes is 1 MB?

This tool counts 1 MB as 1,000,000 bytes (1 MB). Sites that use 1 KB = 1,024 bytes allow 1,024,000 bytes, so a file made here always fits.

How large will my photo be at 1 MB?

Two 3,840×2,160 px photos came out at 3,840×2,160 px and 3,840×2,160 px. Simple backgrounds keep more pixels.

Will the image look bad at 1 MB?

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.
