PDF workflow: merge, number pages and add a watermark

Merge PDF files, number pages and add a text watermark in one operation. Save the recipe as JSON and reuse it with other documents.

1. Add and arrange files

Up to 20 files, 20 MB each, 80 MB total and 500 output pages. Encrypted PDFs are unsupported. Signed PDFs must not be used: editing invalidates signatures. Forms, bookmarks and attachments are not preserved.

    2. Prepare your PDF

    Check the output before using it. Text extraction uses selectable text only; scanned pages need OCR. Choose the dedicated revision tool to reflow text into a new document.

    How to use this tool

    First, the selected source pages are merged in queue order. Continuous page numbers and a text watermark are then added to every page of the combined result; enable at least one of these additions. Page order and duplicates are preserved. Step order is fixed. Recipe JSON includes the watermark text and settings, excluding PDFs, file names and page selections. Opening a recipe keeps your current file queue. Preview the result before downloading. Content is not rasterized; this operation does not compress or sign PDFs.

    1. Choose your PDF files.
    2. Arrange files and select pages; configure page numbers and the watermark, then run all steps with one button.
    3. Prepare, download and check the output in your own viewer.

    Up to 20 input files, 20 MB each and 80 MB total. PDF output: up to 500 pages/100 MB; image ZIP: up to 100 pages/100 MB. Encrypted or signed input is unsupported. Forms, attachments and bookmarks may not survive.

    Also prepare a Word / Excel version of your PDF output

    PDF → Word and Excel: page images + text

    An existing PDF text layer is read automatically and each page image is retained. For scanned/text-free pages, explicitly run Turkish or English OCR. The new document does not exactly reconstruct original tables, formulas or page layout.

    Read text in a listing, product card or screenshot on your device. Select photo areas, correct the text and create new documents with embedded images.

    Word, Excel and report PDFs create a new layout; searchable PDFs preserve the source appearance. Photos are not automatically isolated: select their areas. OCR can make mistakes; check names and numbers before confirming.

    Up to 10 PDF pages/images, 20 MB each, 40 MB total and 16 MP per image. Exported images use a maximum 2000 px long edge; OCR uses 3200 px and source-view PDF uses up to 4096 px. Turkish and English models run locally. Arabic/Japanese models are not installed yet.

    The first photo area replaces the full image; add up to 10 areas afterward.

    Review the suggested table. Excel includes photos, field/value cells and the full text; OCR does not create formulas. Word/PDF reflow the images and reviewed full text.

    Searchable PDF keeps each full source image on one page at its original aspect ratio; OCR is an invisible selectable layer. If the word count changed or geometry is unavailable, choose the text report or rerun OCR. Reports reflow selected photos and edited text.

    A worked example: PDF Workflow

    Save a recipe when you repeatedly merge attachments and add numbering and a watermark.

    Input
    Two PDFs with two pages each
    Settings to try
    Merge → numbering starting at 1 → DEMO watermark.
    Expected result
    A four-page PDF with continuous numbers and a watermark. Recipes exclude source PDFs and file names; step order is fixed.

    This is a plan for the settings above. Inspect the actual preview and downloaded file; image quality, browser support and your input can affect the result.
