FAQ
Are my files uploaded?
No. Compression runs in your browser. Your PDF never leaves your device.
How do I reduce the size of a PDF file?
Load the PDF, pick a compression level, and download. PDFs with lots of images or scans shrink the most.
How do I make a PDF smaller to send by email?
Use a stronger compression level: images get recompressed and the final file becomes much lighter to attach.
How does it reduce size?
Pages are re-rendered and images recompressed. This works best for scanned or image-heavy PDFs.
Does it keep selectable text?
High compression rasterizes pages, which can drop selectable text. Use a higher quality level to retain more fidelity.
Is it free?
Yes. No signup, no limits, no watermark.
