How can I compress an image to exact 20KB or 50KB for government exams?

Upload your photo or signature, switch to Target File Size mode, and select 20KB or 50KB (or enter a custom value). Our compression engine automatically calibrates quality and dimensions using adaptive binary search to hit your exact requirement.

Are my private photos and signatures safe and confidential?

Yes, 100%. Processing runs entirely inside your web browser using HTML5 Canvas. Your sensitive passport photos, signatures, and certificates are never transmitted to or stored on any remote server.

What is the required photo size for SSC, UPSC, and Banking exams in India?

SSC typically requires photos between 20KB and 50KB (200x230 px) and signatures between 10KB and 20KB (140x60 px). UPSC accepts 20KB to 300KB. IBPS and SBI banking portals require 20KB to 50KB for photos and 10KB to 20KB for signatures. Use our 1-click Exam Presets for instant compliance.

Will image compression cause visible blur or pixelation?

Our smart compression algorithm removes redundant metadata and applies perceptual chroma optimization, reducing file size by 70% to 90% while preserving sharp text and clear facial details.
