Frequently asked questions
Is compressing a PDF free?
Yes. ToolPT's Compress PDF tool is completely free with no signup or watermarks.
Will compression reduce the quality of my PDF?
It depends on the level you choose. 'Less compression' keeps the best quality, while 'Extreme compression' produces the smallest file with some quality loss. 'Recommended' balances both.
How much smaller will my PDF get?
It varies by file. Image-heavy and scanned PDFs shrink the most; text-only PDFs are already small, so they compress less. You'll see the exact reduction before downloading.
Can I compress more than one PDF at once?
Yes. Add multiple PDFs and each one is compressed, then you can download them all as a ZIP.
