Frequently Asked Questions

How do I compress an image to under 10KB without making it blurry?▼
Our client-side Smart Loop engine uses discrete cosine quantization to eliminate background paper texture and digital noise while retaining sharp, high-contrast ink lines, ensuring your signature or photo stays crisp under 10KB.
Why do competitive exam portals require images under 10KB?▼
Recruitment portals like UP Police, GATE, and state PSCs process hundreds of thousands of candidate signatures simultaneously. Strict 10KB limits ensure database records load instantly on admit cards.
Can I compress a mobile phone photo of my signature to 10KB?▼
Yes! Crop the photo closely around your signature before uploading. Our in-memory HTML5 Canvas algorithm will scale down the file from multiple megabytes down to strictly under 10KB in seconds.
Are my private signatures and ID photos stored on your server?▼
No! ExactSizeImage.com is 100% client-side with zero backend processing. All compression runs strictly inside your web browser memory. Your documents never touch external servers.
