Published: 2026-11-08
Students' Image-Editing Pains
College students have very practical image needs: thesis figures that look consistent, decent headshots and logos for class presentations, people cut out and styled for club posters, and ID photos with the right background color for resumes. Photoshop, though, is expensive and heavy — and most schools don't hand out licenses.
These five free online tools cover about 95% of what a student needs to do with images.
