Frequently asked questions

How do I compress an image to 25 KB online for free?

Open the Batch Image Optimizer, upload one or more JPEG, PNG, WebP or AVIF files, and set the target file size to 25 KB. The engine auto-tunes compression and resolution until the output hits that size, then you download each optimized file. No sign-up and no upload to any server.

How do I convert PNG to WebP without losing quality?

In the Batch Image Optimizer choose WebP as the target output format and keep the target size generous. WebP typically produces 25-80% smaller files than PNG at the same visual quality. Everything is re-encoded locally in your browser using the HTML5 Canvas API.

Does the optimizer remove EXIF GPS location data?

Yes. Re-encoding through Canvas strips EXIF metadata such as GPS coordinates, device model, and camera serial numbers, so shared photos do not leak your location. Use the "Strip EXIF GPS privacy data" option to make this explicit.

How do I print CNIC front and back on one A4 page?

Open the CNIC & ID Print Suite, upload the front and back images, choose the centered stacked layout, and select A4 paper. The tool aligns both cards to true size at 300 DPI and lets you print directly or export a PDF or PNG sheet.

What is the correct CNIC print size on A4 paper?

A standard Pakistani CNIC is 85.60 x 53.98 mm (3.37 x 2.13 inches), matching the ISO/IEC 7810 ID-1 card format. The print suite locks this aspect ratio and calibrates to true size so the printed copy matches the physical card.

Can I add a "For Bank Use Only" watermark to a CNIC copy?

Yes. Enable the anti-fraud watermark, pick a preset such as "FOR BANK ACCOUNT VERIFICATION ONLY", and adjust the opacity. The overlay is burned into the printed sheet to discourage reuse of the copy.

Are my images and CNIC documents uploaded to a server?

No. All image processing and CNIC alignment happens inside your browser using client-side JavaScript and the HTML5 Canvas API. Your files never leave your device and are never stored remotely.
