Frequently asked questions
Is compressing PDFs free?
You get free compressions every day: 3 a day as a guest, 10 with a free account and unlimited on Pro.
Is the file sent to a server?
No. The PDF is compressed in your browser and never leaves your device.
Can the text still be selected?
No. To reduce the size, each page is converted into an image, so the text is no longer selectable. That's why it works best with scanned documents.
Which level should I choose?
Light keeps more quality; strong reduces the size more. Try balanced and check the result before downloading.
What if the PDF is already optimized?
If the tool can't reduce the size, it tells you and won't produce a larger file.
