Why 150 KB?
Some forms and email systems cap attachments at 150 KB. The tool above is set to 150 KB, and a green ✓ badge shows when the file fits.
If your form also gives a pixel size, use the Image resizer to set it with the 150 KB limit. Smaller dimensions leave more of the 150 KB budget for detail.

Frequently Asked Questions

Does it work on phones?
