Why Resize Images to 20KB?

To​‍​‌‍​‍‌​‍​‌‍​‍‌ make data processing more efficient and to save on upload time, various government portals, job application platforms, and academic systems from around the globe impose hard file size limits. Among these, the 20KB limit is most frequently seen in the case of passport photos, signature images, and other types of official documentation that are submitted as part of civil service exams, university admissions, and professional ​‍​‌‍​‍‌​‍​‌‍​‍‌certifications.

Conventional​‍​‌‍​‍‌​‍​‌‍​‍‌ photo editing tools usually involve a cumbersome trial-and-error process with quality sliders, which most of the time lead to files that exceed the size limits or have a low visual quality. Our smart compression algorithm removes this need for guessing by determining the best interaction between image dimensions and compression quality to get your exact target size with the least possible clarity ​‍​‌‍​‍‌​‍​‌‍​‍‌loss.
