Frequently asked questions
Will my PDF text still be selectable after compression?
No. Each page is re-rendered as an image during compression, so text in the result is no longer selectable or searchable. This trade-off is what makes heavy compression possible for scanned documents and image-heavy PDFs.
Is my file really never uploaded?
Yes. The entire process runs in your browser using your device's own processing power. Your PDF never leaves your computer, which means no server stores it, no third party can access it, and there is no upload wait time.
What if my PDF is already small and compression makes it bigger?
If the compression would increase the file size, the tool keeps your original file unchanged and lets you know. You will not accidentally end up with a bloated document.
How small will my compressed PDF be?
The reduction depends on your document's content. Scanned pages and image-heavy PDFs typically shrink the most, while text-only PDFs may see minimal change. The tool shows you the result size so you can evaluate the outcome before downloading.
