Questions about Compress PDF

How do I compress a PDF to 100 KB?

Choose "Target size" and select 100 KB. MiniPDF lowers image resolution step by step until the file fits, then shows the final size before you download.

Will the text stay sharp?

"Light" compression keeps everything exactly as it is. "Recommended", "Strong" and target sizes turn each page into an optimized image, so text stays readable but can no longer be selected or searched.

Is my PDF uploaded anywhere?

No. Compression runs inside your browser, so the file never leaves your device.
