  • ✅ University Admissions: Uploading previous marks sheets.
  • ✅ Voter ID Portals: NVSP form attachments require tiny file sizes.

Frequently Asked Questions

How to compress PNG to 100KB?

Upload your image to our 100KB compression tool. The tool automatically calculates the exact quality settings needed to shrink your image below 100KB securely.

Is the 100KB limit strict?

Yes. The algorithm ensures the final output file is guaranteed to be 100KB or smaller, perfect for form limits.

Do government portals accept these images?

Absolutely. Images exported from our tool retain valid PNG encoding and work flawlessly on Aadhaar, PAN card, and other government portals in India.

What if it gets pixelated?

If your original image is extremely huge (e.g., 10MB), reducing it to 100KB will reduce its visual fidelity. We recommend cropping out unnecessary backgrounds first.

Is my data safe?

100% safe. Processing happens directly on your device via web browser technology. We never see your images.

Can I do this on my smartphone?

Yes! Our tool is fully responsive and allows you to use your mobile camera roll to compress images.
