Frequently Asked Questions

Is this PDF Editor 100% free with no watermarks or hidden trial traps?

Yes! Checkistan PDF Editor is completely free and never inserts any promotional watermark, logo, or fee onto your exported PDF documents.

Are my confidential documents uploaded to any third-party servers?

No. All PDF loading, rendering, text overlay embedding, and file compilation run 100% locally inside your web browser using client-side WebAssembly and JavaScript engines. No files are ever transmitted across the network.

Will the edited PDF look crisp when printed at 300+ DPI?

Yes. The editor embeds native PostScript vector fonts (Helvetica, Times Roman, Courier) and vector shape layers directly into the PDF byte stream, ensuring crystal-clear print quality and scalability without rasterization blur.

Can I reorder, rotate, or delete individual pages in a multi-page PDF?

Yes. The left-hand thumbnail sidebar lets you rotate sideways pages, drag to reorder sheets, duplicate template pages, delete unwanted pages, insert blank sheets, and extract single pages into standalone PDF files.
