Many competitive exams, university admissions, and online recruitment portals (such as UPSC, SSC CGL, NTA NEET/JEE, IBPS, and State PSCs) impose strict document upload rules requiring PDFs to be within an exact size limit — for example, "PDF must be between 100 KB and 200 KB" or "Exactly under 500 KB".

Our free online Image to PDF Converter with Target Size Engine automatically balances multi-pass image compression and precision byte-padding so that your generated PDF matches your Exact Target KB without sacrificing text clarity.

Frequently Asked Questions (FAQ)

How does the exact target size in KB work? +
Our tool performs multi-pass resolution optimization to ensure your images fit within the specified byte limit, and applies safe binary padding so that the final PDF matches your target KB requirement.
Will the text in my scanned certificate remain readable? +
Yes. The compression algorithm maintains high contrast on text edges and high dpi balance, ensuring your marksheet or certificate remains sharp for online verification.
Can I leave the target size empty for original quality? +
Yes! If you select "Auto" or leave the Target Size input empty, the converter will generate the PDF at full native photo resolution without target padding.
