Frequently asked questions
Change text
Click marked PDF text and type in the contextual panel. Changes apply automatically. You can also draw a box over the text. The edited copy is rebuilt as images at up to 144 dpi. Erased regions are removed from the output; the entire document loses selectable text, links and layers. Replacement fonts are approximate. Keep the original. No OCR or digital signatures.
Does Compress PDF always make the file smaller?
No. It mainly reduces photos and scans; text stays text and fonts are not touched. An already optimized or text-only PDF may not shrink: we tell you and do not offer a pointless download. Keep your original.
What happens to signatures and forms?
Encrypted PDFs, signatures and interactive forms are rejected. Protection is not removed, documents are not signed and fields are not automatically flattened.
Can I change page order?
Yes. In Extract and reorder, enter the desired order, such as 3,1-2. Repeat pages with 1,1,2. To merge, order the files using the buttons before creating the result.
Can a watermark hide private data?
No. It adds text over the document. Removing information requires a real redaction tool.
