Frequently Asked Questions
Why is the text no longer selectable after compressing?
This tool compresses by converting each page to an optimized image, which is what makes scanned PDFs so much smaller. If you need selectable text, keep the original.
Which PDFs compress the most?
Scanned documents and PDFs full of high-resolution images shrink dramatically. PDFs that are mostly plain text may not get much smaller.
Are my files uploaded?
No. Compression runs entirely in your browser.
