# Sign PDFs online.

Add a signature to a PDF, compress the result, and export the finished document from the same workspace.

Add a signature, approval note, or stamp, then compress the final PDF before downloading or emailing it.

## Questions

### Does BitePDF show the compression result before checkout?

Yes. BitePDF shows original size, output size, and saved percentage before you choose an export plan.

### Can I change compression strength?

Yes. The compression picker lets you choose Low, Medium, or High. Low favors quality, Medium balances quality and size, and High targets the smallest export.
