Useful tools, without the detour.

Paper Desk is part of Global Core Hub, a collection of small browser tools. This desk focuses on everyday PDF page operations.

What we build

Each tool has a specific task, a visible result and a short explanation of its limits. You can use the core functionality for free without signing up. File and text processing happens on your device. Optional advertising helps support operation.

Report a problem

Contact the operator through the Global Core Hub public profile. Include the tool name, browser version and steps to reproduce the issue. Please do not send passwords, access tokens, private documents or personal information. We do not provide a live support chat or guaranteed response time.

Keep your originals

Download results as new files and inspect them before replacing an original or relying on an important calculation. Tools are convenience utilities and may have format-specific limits.
