About ResizeKB

Our Story

ResizeKB was born from frustration. We were applying for a government exam and needed to resize our photo to exactly 20KB. Every tool we tried either added watermarks, required payment, or gave us 19KB or 21KB - never exactly what we needed.

So we built our own solution. A tool that hits the exact file size you need, works completely in your browser for privacy, and is 100% free forever.

Why We're Different

Privacy First

Your images never leave your device. All processing happens in your browser using JavaScript. No servers, no uploads, no data collection.

Actually Free

No premium tiers, no feature restrictions, no watermarks. Everything you see is free to use, always.

Exact Sizes

Need exactly 20KB? You'll get exactly 20KB (within 5% tolerance). No more rejected applications due to file size errors.

Made for India

Built specifically for Indian users - Pan Card, RRB, SSC, UPSC requirements built-in with exact specifications.

Who We Help

  • Government exam applicants (RRB, SSC, UPSC, state exams)
  • Job seekers uploading resumes and photos
  • Students applying for universities and scholarships
  • Anyone applying for Pan Card, Aadhaar, or passport
  • Professionals needing exact file sizes for applications

Our Mission

To provide the best free image compression tool available. No gimmicks, no upsells, no data collection. Just a tool that works exactly as it should.

We believe access to quality tools shouldn't require payment. If you've been helped by ResizeKB, share it with others who might need it.
