Frequently asked questions
Does compressing a PDF blur the text?+
Text usually stays intact; it's mainly images that get re-compressed to save space. Stronger compression lowers image quality, so check the preview.
Is the document sent to a server?+
No. Compression runs in your browser, so the PDF never leaves your device.
Can I meet an email attachment size limit?+
Higher compression can shrink the file substantially, which helps fit attachment limits.
