Flachmodus

Flattening rewrites the PDF and can invalidate cryptographic digital signatures. Use this when the visible signature or markup appearance needs to be final.

Dažniausiai užduodami klausimai

What does flattening a PDF do?

Flattening makes visible form fields, annotations, markups, signature appearances, and layer output part of the PDF page content so the file is more final for upload, printing, or filing workflows.

Does PDF flattening reduce quality?

No. The default mode uses Ghostscript PDF output with image downsampling disabled. It does not use full-page rasterization, lower resolution, or compression as a load-saving shortcut.

Will flattening affect digital signatures?

Yes. Flattening rewrites the PDF structure and can invalidate cryptographic signatures. Use it when you need the visible signature or markup appearance finalized, not when you need signature validation preserved.

Can I flatten an encrypted PDF?

Unlock the PDF first if you know the open password and are authorized to modify it. Encrypted PDFs are not flattened directly.

Ar įkelti PDF failai yra privatūs?

Files are processed in short-lived temporary storage and automatically deleted after processing. Filenames, form values, annotations, signatures, and document text are not sent to analytics.
