Technical Specifications & Requirements
Why Strict 50KB File Limits Exist
Many government job application systems, state civil service portals, and biometric visa upload forms were architected in the mid-2000s with strict database blob limits. They reject any upload measuring 50.1 KB or higher.
Pixena solves this through an automated target size compressor. Instead of forcing you to guess between 60%, 45%, and 30% quality sliders, our binary search algorithm samples file output in browser memory, converging on the highest possible visual clarity that measures strictly beneath 50,000 bytes.
Frequently Asked Questions
Will my image look blurry at 50KB?
Pixena balances resolution and compression quality to retain facial features, document text, and sharp outlines while satisfying the 50KB threshold.
Are my personal application photos uploaded to your server?
No. Pixena runs entirely in your browser using HTML5 Canvas. Your sensitive resume photos and government IDs never leave your computer.
What if my original photo is 10MB?
Pixena intelligently downscales huge multi-megapixel dimensions first, then fine-tunes JPEG quality to reliably reach under 50KB.
Can I compress PNG images to 50KB?
Lossless PNG photos are rarely able to reach 50KB; Pixena automatically converts photographic inputs to JPEG or WebP to meet strict budgets.
Is this tool free to use?
Yes, 100% free with no watermarks and no registration required.
Can I download the resulting photo on mobile?
Yes, tap Download to save the 50KB image directly to your iPhone camera roll or Android download folder.
