Is it free to compress a PDF without a watermark?
Updated July 2026
Yes — Arthize lets you compress a PDF free with no watermark on the output. Compressing a PDF reduces file size — often 50–90% on image-heavy scans — by down-sampling images and stripping redundant data, while keeping text selectable. Paid plans only raise file-size and monthly limits.
