How to Make a 600×600 JPG at 300 DPI Under 240 KB
Combine pixels, JPEG output, DPI metadata and a file-size ceiling in the right order.
Open the toolOpen 600×600 / 300 DPI / 240 KB preset →Lock the pixel canvas first
Resize or crop to 600×600 before final compression. Changing dimensions later changes the encoded size again.
Set JPEG and DPI metadata next
JPEG format and 300 DPI metadata are separate from pixel dimensions. DPI metadata does not create more pixels.
Optimize the final file last
Apply the 240 KB ceiling after geometry and format are fixed, then verify the receiving portal before submission.
