- Add signature to PDFThe workspace below is built for contracts, forms, and sign-and-return tasks. Upload your PDF, add your signature, align it on the live preview, then choose whether it applies to the current page only, a custom page range, odd/even pages, or the full document. The same engine also powers our related stamp and logo pages.
- Add stamp to PDFUpload your PDF, then add your stamp as an image (transparent PNG works well) or draw a simple mark. Position it on the preview, choose which pages receive it—single page, range, all, or odd/even—and download. If you describe the task as signing instead of stamping, use Add signature to PDF; the underlying workspace is shared.
- Add logo to PDFUpload your PDF and your logo file (PNG with transparency or JPEG). Position and scale it on the preview—header, footer, or cover area—then apply to one page, a range, or all pages. For circular seals, see Add stamp to PDF; for handwritten marks, see Add signature to PDF.
- Batch stamp PDFUpload your PDF and your stamp image. Position it once on the preview, then use page scope options to cover a range or the entire document in a single apply step. You still work on one PDF file per session; the “batch” value is applying the same stamp across many pages without repeating clicks per page.
- Stamp PDF multiple pagesAfter you upload your PDF and stamp image, use the page controls to limit stamping to this page, a custom from–to range, all pages, or odd/even sets. The preview shows the active page so you can verify placement before you apply across the selected set.
- Apply stamp to all pages PDFUpload your PDF and stamp image, position it on the preview, then select the all-pages apply mode before you run apply. You get one output PDF with the stamp merged on each page at the same relative location. For partial coverage, use Stamp PDF multiple pages or Batch stamp PDF.
- Alternate and mix PDFsUpload multiple PDFs, set how many pages to take from each before switching, choose regular or reverse page order, preview the result, and download one mixed PDF. Built for comparison packets, bilingual layouts, and combined proofs.
- Delete PDF pagesUpload a PDF, mark pages to remove with thumbnails or page ranges, preview what remains, and download a cleaned file. Built for contracts, board packs, and classroom materials.
