Where a 150 KB limit is used

A 150 KB limit is most often used for scanned mark sheets and multi-page certificates. A 150 KB limit suits detailed scanned documents like mark sheets and certificates where the text must stay sharp. It is common on admission and document-verification portals.

Tip for hitting 150 KB cleanly

Keep the scan straight and well-lit; a clean, well-aligned scan compresses to 150 KB with readable text, whereas a skewed or shadowed scan needs a larger file to stay legible.

⚠️ File-size rules vary between forms and change between exam cycles — always confirm the exact limit in the official notification before you upload.

Frequently asked questions

Will my mark sheet stay readable at 150 KB?
Yes, if you scan it clearly. At 150 KB a typical A4 mark sheet keeps its numbers and text legible for verification.
How do I compress an image to 150 KB?
Upload your photo above — the target is already set to 150 KB. Click Compress and the tool lowers the quality just enough to bring the file at or under 150 KB, then lets you download it. Nothing is uploaded to a server.
Will the image still be clear at 150 KB?
The tool keeps the highest quality possible while meeting the 150 KB limit. For scanned mark sheets and multi-page certificates, 150 KB is enough to stay clear; very small targets naturally soften the image more.
Is it free and private?
Yes — completely free, no signup, no watermark, and the compression runs entirely in your browser so your file never leaves your device.
