Frequently Asked Questions
Everything you need to know about this tool.
How does Docutomic compress a PDF to a specific target size?
Docutomic uses an iterative client-side compression pipeline. It renders and evaluates page elements, adjusting canvas resolution and JPEG compression levels to bring the actual measured PDF size as close as possible to (or under) your specified target size.
Can I enter a custom target size in KB or MB?
Yes. Select the 'Custom' preset, type your desired numeric size, and toggle between KB and MB. The optimizer will calibrate document parameters to meet your requirement.
What happens if my target size cannot reasonably be reached?
If a document has many pages or complex content that cannot physically reach your target without rendering text illegible, Docutomic generates the best possible readable compressed version and clearly explains the final size achieved.
Are my confidential PDF documents uploaded to an external server?
Never. All compression runs entirely in your web browser using WebAssembly and HTML5 Canvas. Your confidential contracts, financial statements, and personal records never leave your device.
Does this tool add watermarks or impose page limits?
No. Docutomic is 100% free with no watermarks, no account creation, and no artificial restrictions.
