Flexible Image Compression for Every Need

Easily reduce your photo or scanned signature to 30KB online. Fast, secure, and perfect for online exam forms, passport applications, and official uploads.

Use Case

Ideal for students and job seekers. Many academic admission portals (like JEE, NEET), banking recruitment exams (IBPS, SBI), and visa applications strictly require passport-size photos and signatures to be under a 30KB file size limit.

How It Works

A 30KB file limit gives you a slightly better balance of quality compared to extreme compression, ensuring your face or signature remains crisp and clear for official review. To get your image under 30KB, our tool intelligently scales the maximum width to 700px and applies an optimized JPEG compression rate. If your original image is a massive smartphone photo, resizing the physical dimensions is the secret to shrinking the file size drastically without creating heavy pixelation. Best of all, this tool runs entirely in your browser—meaning your private ID documents and personal photos are processed securely on your device and never uploaded to a remote server.

What You Get

Optimized images that balance quality and file size for faster uploads — with exact target sizes, AVIF/WebP/MozJPEG codecs, and unlimited batch ZIP export.

Frequently Asked Questions

Everything you need to know about compressing images online.

Yes. Almost all government and educational portals explicitly require JPEG or JPG formats. It also provides the most efficient file size reduction for complex images like photographs, which is why our tool defaults to JPEG.

If your file is still slightly too large, you can easily fix this using the settings. Try lowering the 'Max Width' to 500px or 600px, or adjust the 'Quality' slider down to 40% and click compress again.

Not necessarily! 30KB is usually plenty of data for a standard passport-sized photo or a scanned signature. By shrinking the dimensions (width and height) alongside the quality, the image will remain sharp enough for official approval.

Yes, 100% secure. The compression happens directly inside your web browser. We do not have access to your files, and nothing is ever stored on our servers.
