FAQ
Are my files uploaded anywhere?
No. Compression happens in your browser using JavaScript. Your PDF never leaves your device.
Why isn't the text selectable in the result?
This tool compresses by re-rendering each page as an image at reduced quality. That's what makes the file smaller, but it means text can no longer be selected or searched in the output.
Which level should I pick?
Start with "Low compression" if quality matters most. Use "High compression" for the smallest possible file, e.g. for email attachments.
