Back to the overview: [PDF Tools](https://www.jpkc.com/db/en/tools/pdf/) · Open the tool live: [www.jpkc.com/tools/pdf/](https://www.jpkc.com/tools/pdf/)

The [Manual](https://www.jpkc.com/db/en/tools/pdf/manual/) explains every tab and feature in detail. This page adds **concrete workflows**: typical tasks played through step by step. The interface is in English, so tab and button names appear in their original spelling.

## Example 1: Merge two PDFs into one

The classic — you have a cover sheet and a main document and want both as a single file.

1. Open [PDF Tools](https://www.jpkc.com/tools/pdf/) and switch to the **Merge & Split** tab. The **Merge** sub-tab is already active.
2. Drag the first and second PDF files in one after another (or both at once) onto the drop zone. Both appear in the table with page count and size.
3. **Check the order.** The merged PDF takes the table order top to bottom. If the cover sheet should come first, move it up to the first position with the up arrow.
4. Click **Merge All**. The tool copies all pages of both files, in the order shown, into a new document.
5. Download the result via **Download Merged PDF** as `merged.pdf`.

The pattern scales: you can add any number of files, reorder them, and merge in one go. At least two are required.

## Example 2: Extract specific pages from a PDF

You only need pages 1 to 3 and page 10 from a 40-page report — say, for an excerpt.

1. Switch to **Merge & Split** and there to the **Split** sub-tab.
2. Drag the PDF file onto the drop zone. The tool shows the name, size and total page count.
3. Leave the mode on **Extract page ranges** and enter `1-3, 10` in the field. Comma-separated, you can freely combine single pages and ranges.
4. Click **Split**. This produces **one** file with exactly those four pages (1, 2, 3, 10), in ascending order.
5. Download it from the results list (`split_1.pdf`).

If instead you need **each page separately**, pick the **Extract each page as single PDF** mode — you then get one file per page. And with **Split every N pages** you break a large PDF into equal chunks (for example one part every 10 pages).

## Example 3: Fill in a PDF form

You have a PDF with interactive form fields (an application, say) and want to fill it in on screen, without printing it.

1. Stay in the default **Viewer & Editor** tab and drag the PDF onto the drop zone (or **Browse Files**).
2. The embedded viewer shows the form fields as **fillable fields**. Click into them and enter your values; operate dropdowns and checkboxes directly.
3. Once all fields are set, save via the viewer's **Save** function. The completed form is downloaded as a new PDF file.

Note: there is no server-side storage — your completed form exists only as a local download. That is exactly what makes this safe even for sensitive applications, because the document never leaves your browser.

## Example 4: Annotate, highlight and sign a PDF

You need to comment on a contract PDF, mark a passage, and sign it at the end.

1. Open the PDF in the **Viewer & Editor**.
2. **Highlight:** activate the **Highlight** tool, pick a colour, and drag over the relevant text passage.
3. **Add a note:** with **FreeText** you place a text note directly on the page — colour and font size are adjustable.
4. **Draw:** if you need an arrow or a handwritten mark, use **Ink (Draw)** with colour, opacity and stroke width.
5. **Sign:** via **Signature** you create and place your signature; alternatively, use **Stamp** to insert an image (such as a seal).
6. Save the result via **Save** — all annotations are contained in the downloaded file.

If you just want to check what the document says, the **Text** button helps alongside: it pulls out all text content (with word and character statistics) for you to copy or save as `.txt`.

## Example 5: Turn Markdown into a clean PDF

You have a README or docs in Markdown and need a tidy, **searchable** PDF from it.

1. Switch to the **Convert** tab, **Markdown** sub-tab.
2. Type your Markdown into the editor, load a `.md` file via **Open File**, or click **Load Example** to see the supported elements (headings, lists, code blocks, tables, blockquotes, links).
3. Under **Page Settings** pick the format, orientation, font size and margin.
4. **Generate PDF** renders the preview; page through it with the arrows.
5. **Download** saves `markdown.pdf`. Because pdfmake produces real text, you can search and copy text in the result.

If you need visual CSS styling rather than plain body text, the **Rich HTML** sub-tab is the way — but note that its output is **raster** and therefore not searchable (see [Tips & Tricks](https://www.jpkc.com/db/en/tools/pdf/tips/#simple-html-or-rich-html-the-decision-that-matters)).

## Example 6: Bundle several images into one PDF

You want to hand over a set of screenshots or scanned receipts as a single PDF.

1. Go to **Convert** → **Images**.
2. Drag all images onto the drop zone. Supported are JPG, PNG, WebP, GIF, BMP and TIFF; each image lands on its own page.
3. Set the **Fit Mode** per image or globally: **Fit** places the image without loss (default), **Fill** fills the page and crops, **Stretch** distorts to the area.
4. Set the format, orientation and margin under **Page Settings**.
5. **Generate PDF** → **Download** saves `images.pdf`.

If the images still need cropping or converting to the right format, do that in the **[Graphic Editor](https://www.jpkc.com/db/en/tools/graphic/)** and then bundle them here.
