Convert PNG to JPG Under 20KB
Privacy-first batch converter. Process your PNG photos to JPG locally in-browser.
Locking Images Under 20KB Client-Side
Submitting documents to government systems, university admission pages, or visa portals often demands photos strictly under 20KB. BatchPix executes a binary search quantization loop entirely in your browser memory to scale down quality factors until the byte constraint is met.
Because operations occur 100% locally inside the HTML5 Canvas node, your sensitive personal documents or signatures never travel over networks, guaranteeing data isolation.
Frequently Asked Questions
How is the under 20KB limit enforced?
The conversion loop iteratively runs canvas compression, assessing the output size in RAM and adjusting the quality step until it sits under 20KB.
Is text readable in a 20KB file?
Yes, our quantization algorithm prioritizes border sharpness, maintaining readability for scanned signatures and official certificates.
