Frequently Asked Questions

Why do forms ask for images under 50 KB?

Many exam, visa, passport and job application portals only accept small files. This tool shrinks the image to fit the limit while keeping faces and text clear.

Will a large phone photo fit under 50 KB?

Yes. When quality alone is not enough, the photo is made smaller in pixels until it fits, which keeps faces clear. If your form asks for exact dimensions, set them under "Exact size (px)" first.

Is it safe to compress my ID or passport photo here?

Yes. The image is processed on your device, and nothing leaves your computer or phone.
