How PDF compression works here
Light re-saves the PDF more efficiently and keeps text selectable — good for PDFs that are already mostly text. Recommended, Strong and Extreme re-draw each page as an optimised image, which gives much bigger savings on scans and photo-heavy files. Text in these modes becomes part of the image, so it can still be read and printed but not selected or searched.
Popular targets: compress PDF to 100 KB, 200 KB, 500 KB and 1 MB. For tips, read how to reduce PDF file size.
Frequently asked questions
How much smaller will my PDF be?
Scanned and photo PDFs usually shrink by 50–90%. Text-only PDFs are already small and may only shrink a little.
Will the text still be readable?
Yes. “Recommended” keeps documents clear. “Extreme” is for when the size limit matters more than sharpness.
Can I compress a PDF to exactly 100 KB?
Choose 100 KB as the target size. PDFMint tries progressively stronger settings and stops at the best quality that fits under 100 KB.
Is it safe to compress PDFs here?
Yes. Your PDF never leaves your device — all processing happens in your browser, so nobody (including us) can see your file.
