If there is not much excess, you can compress the contents of the first page a little. When printing, you can control the number of pages by setting the length and width of the paper to "narrow".

If there are many redundant places, simply expand some contents, such as work experience, work content, personal statement and project experience, and make your resume into two pages.

There is no rule that a resume can only be one page, so you should do it according to your actual situation.
