Frequently Asked Questions
Will the quality drop?+
Light keeps everything. Good, Balanced and Maximum turn each page into an image with lower quality — Balanced is usually fine for reading and email.
Why can I not select text after compressing?+
Stronger levels convert pages to images to save space. Use Light if you need selectable text.
Is there a size limit?+
Up to 200 pages in the stronger modes. Very large files depend on your device memory.
Is my data safe?+
Yes. Everything runs inside your own browser. Your text, files and images are never uploaded to any server.
Is this tool really free?+
Yes — completely free, no signup, no watermark and no usage limit.
