Compress PDF to 150KB

Bring a scanned document to about 150KB for CUET, state scholarship portals and similar uploads. Everything happens in your browser.

Frequently asked questions

Is 150KB enough for a scanned marksheet?

Usually yes for one or two pages. Detail survives well at this size, which is why several portals settled on it.

What if my portal asks for 100KB instead?

Use the 100KB page. Compressing further than required costs readability with no benefit.

Is my PDF uploaded to a server?

No. The whole process runs in your browser using your own device's processing power. The file never leaves your device, which matters for identity and financial documents.

Is there a watermark or a sign-up?

Neither. The tool is free to use with no account and adds nothing to your document.

When you need a 150KB PDF

150KB sits in the range CUET and several state scholarship portals use for supporting documents — marksheets, income certificates, domicile proofs. It is roomy enough that a one or two page scan usually stays comfortably legible.

Why 150KB is easier than 50KB

Tripling the budget makes a large practical difference. At 150KB a scanned marksheet keeps enough detail that printed tables and small print remain readable, which matters when a verifying officer has to read the document rather than just receive it.

Check the limit before you compress

Portals state their limit in the instruction sheet, and it changes between notifications. If yours says 100KB or 200KB rather than 150KB, use the matching page below — compressing to a smaller size than required only loses quality you could have kept.

If the result still looks soft

Soft output at 150KB usually means the original scan was very large or very noisy. Rescanning at a lower DPI often beats compressing a huge file: a 150 DPI scan starts near the target and keeps more real detail than a 600 DPI scan crushed down to fit.

Check your portal's actual limit

Upload limits change between notifications and differ by document type, so treat 150KB as the size you were asked for rather than a universal rule. The instruction sheet on your application portal is the authority; if it names a different figure, use the matching page below.
