Focused document tools, tested against real workflows.

smallpdf.app builds free, straightforward tools for common PDF, document, and image tasks. Each tool is designed around one clear outcome, with its limits stated alongside the workflow.

How guides are created

The smallpdf.app editorial team checks each guide against the current product before publication. Instructions are based on the controls and output a user can verify in the live tool, not on unsupported claims or a target word count.

How guides are reviewed

Guides are revisited when a tool gains a capability, changes its workflow, or needs a clearer safety distinction. A modified date changes only after a substantive review or update.

Important document boundaries

Visible signatures are not certificate-backed digital signatures. Cropping, whiteout, and visual replacement are not secure redaction. When a workflow rewrites or flattens a PDF, keep the original if signatures, editability, or archival fidelity matter.

Corrections

If a guide and a working tool disagree, the guide should be corrected. The current tool behavior and its visible limitations remain the source of truth.
