Frequently asked questions
What is lost with strong compression?
Selectable text, forms, links, annotations as interactive objects, and accessibility structure are removed. Editing also invalidates digital signatures. Use standard mode when these features matter.
Do I need an account?
No account or payment is required. File processing depends on browser capabilities and device memory; any tool-specific limits appear beside the inputs.
