Frequently asked questions

How does PixelKit compress images to an exact KB size?

PixelKit uses an iterative binary-search algorithm running locally in Web Workers. It tests compression quantization levels until the output file fits directly under your target limit (e.g. 50 KB, 100 KB, or 200 KB) with maximum visual clarity.

Can I compress images to under 50KB or 100KB for government application forms?

Yes. PixelKit has dedicated presets for 50KB, 100KB, 200KB, and 500KB specifically tuned for Aadhaar, PAN, passport, UPSC, and university application portals.

Which image format compresses to the smallest file size?

WebP and AVIF generally produce 30% to 50% smaller files than JPG and PNG while maintaining identical visual quality. If your target portal accepts only JPG or PDF, PixelKit will optimize those formats to their absolute limits.

Is there a limit to how many images I can compress?

No. PixelKit does not impose daily limits, file counts, or upload paywalls. You can drop batches of photos and compress them in parallel.

Are my confidential documents and ID scans private?

Yes, 100%. PixelKit never uploads your files to any remote server. Everything is decoded, compressed, and downloaded directly inside your browser.
