Frequently Asked Questions
How do I compress an Aadhaar photo to exactly 200 KB?
Upload your photo, enter "200" in the Target File Size box, and click download. PixelSize automatically adjusts the quality and dimensions to hit exactly 200 KB without blurring your image.
Is it safe to upload my PAN card or ID photos here?
Yes, 100% safe. PixelSize runs entirely in your browser. Your photos are never uploaded to any server, meaning no one else can see or access your documents.
Does PixelSize add a watermark to my compressed image?
No. We never add watermarks, logos, or stamps to your files. The downloaded image is clean and ready to upload to any government portal.
Can I compress PDFs to a specific file size?
Absolutely. You can upload a PDF and set a target KB (e.g., 500 KB). The tool will compress the PDF to match your exact size requirement.
