Compress Image to 1.5 MB (1536 KB) — 1.5 MB to KB

Where a 1.5 MB limit shows up

• Scanned certificates and marksheets
• Aadhaar, PAN and KYC document scans
• Bank statements and salary slips
• Visa and job-portal supporting documents
• Portals with a 1.5 MB or 2 MB attachment cap

Tips for a clean 1.5 MB file

• •1.5 MB = 1,536 KB. If your form says '1500 KB max', this tool's output can land between 1,500 and 1,536 KB — use the 1 MB tool to be safe.
• •For documents, tick Keep original dimensions so text, stamps and signatures stay crisp — only JPEG quality is lowered, no crop.
• •Scan in good light on a flat surface; shadows and creases cost KB and make text harder to read.
• •Batch your files before you start the form. Many portals time out the session while you go hunting for the next document.

Frequently asked questions

How many KB is 1.5 MB?

1.5 MB is 1,536 KB in the binary count most computers use (1 MB = 1,024 KB). Some portals count 1 MB as 1,000 KB, making 1.5 MB = 1,500 KB. If your form gives a KB number, go by that number.

How do I compress a scanned document to 1.5 MB without blurry text?

Tick Keep original dimensions before choosing the file. The pixel size stays the same and only JPEG quality is reduced until the file is under 1.5 MB, so fine print stays readable.

Are my Aadhaar, PAN or certificate scans uploaded to your server?

No. Compression runs entirely inside your browser, so sensitive documents never leave your device.

Can I compress a PNG or phone photo to a 1.5 MB JPG?

Yes. Choose any JPG or PNG your browser can open and you download a JPEG under 1.5 MB. PDF files are not supported yet.

Why did the portal reject my 1.5 MB image?

Usually the file was a few KB over the limit, the portal counts 1.5 MB as 1,500 KB, or it also caps width and height. Check the exact KB number and dimensions in the form instructions.

Is my image uploaded to a server?

No. ShantiTools compresses the image entirely inside your browser — the file never leaves your device.

Common mistakes

• •Uploading a screenshot — screenshots are already compressed and often produce blocky JPEGs. Use the original photo instead.
• •Ignoring dimensions — a file can be the right KB but the wrong shape. This page sets 1800×2200 px automatically.
• •Cropping too tightly — leave a small margin around the head and shoulders so the form does not cut the face.
• •Wrong background — busy backgrounds eat KB and can get rejected. Plain white or light works best.

Troubleshooting

The result is still too big

Start with a smaller source file or crop closer to the face. If the form allows a smaller size, try 1 MB.

The result is too small

The source image may be very low resolution. Upload a larger original photo and retry.

My form rejected the upload

Double-check both the KB limit and the pixel dimensions in the form. Some forms also require exact aspect ratios (e.g. 3.5×4.5 cm).
