# PDF tools

Merge, split, rotate, reorder, watermark and convert PDFs in your browser. Files never leave your device.

Link in Seconds has 8 free PDF tools. Every one of them runs inside your browser, on your own device. Your document is never sent to a server to be processed, and you do not need an account to use them.

The PDF tools hub at /pdf-tools

## All tools

| Tool | What it does |

| [Merge PDF](https://linkinseconds.com/merge-pdf) | Merge PDFs into one document in your browser. Drag to reorder, merge in seconds, then download it or turn it into a shareable link. Files never leave your device. |

| [Split PDF](https://linkinseconds.com/split-pdf) | Split one PDF into several, or pull out just the pages you need, type a range like 1-3, 7. Runs entirely in your browser, so the document is never uploaded anywhere. |

| [Compress PDF](https://linkinseconds.com/compress-pdf) | Compress a PDF in your browser. Keep quality is lossless; Strong turns pages into images for big wins on scans. Text PDFs barely shrink. Nothing is uploaded. |

| [Rotate PDF](https://linkinseconds.com/rotate-pdf) | Turn every page, or just the ones that came out sideways from a scanner, and save the rotation permanently. Free, no sign-up, and the file stays on your device. |

| [Organise PDF](https://linkinseconds.com/organize-pdf) | See every page as a thumbnail, drag them into the right order, and delete the ones you don't want. Everything happens in your browser, nothing is uploaded. |

| [Watermark PDF](https://linkinseconds.com/watermark-pdf) | Stamp DRAFT, CONFIDENTIAL or any text diagonally across every page before you send a document out. Free, in your browser, with nothing uploaded to a server. |

| [JPG to PDF](https://linkinseconds.com/jpg-to-pdf) | Turn photos or scans into one PDF, one image per page, in the order you choose. Ideal for sending a photographed document as a proper file. Runs in your browser. |

| [PDF to JPG](https://linkinseconds.com/pdf-to-jpg) | Turn each page of a PDF into a JPG you can paste into a slide, a chat or a listing. Pick the pages and the quality; the conversion happens on your own device. |

You can also open any tool from the [PDF tools hub](https://linkinseconds.com/pdf-tools), from the **Tools** group in the dashboard sidebar, or from the site menu.

## How to use a tool

- ### Pick your file Open a tool and drop your PDF (or images, for JPG to PDF) on the picker, or tap to browse. Merge PDF takes several PDFs at once.

- ### Choose your options Each tool has only the options it needs. For example, Split PDF takes a page range such as 1-3, 7, Compress PDF offers **Keep quality** or **Strong**, and Watermark PDF asks for the text to stamp.

- ### Download or share When the result is ready, click **Download**. If a tool made several files, **Download all as zip** saves them in one go. To send it to someone, click **Share it as a link** (or **Share them as one link** for several files).

## Your files stay on your device

- The file is read and changed by your browser. No copy is uploaded while you use a tool.

- There is no sign-up and no daily limit.

- **Share it as a link** carries the result to the upload card on the home page. It is only uploaded when you publish it there, like any other upload, and then the normal [plan limits](https://linkinseconds.com/docs/plans-and-limits) apply.

Files up to 40 MB

Because the work happens in your device's memory, a tool accepts up to 40 MB of files per job. Phones in particular can close a tab that uses too much memory. If your file is bigger, split it first or work on it in parts.

## Good to know

### Compress PDF

**Keep quality** is lossless and keeps text sharp, but a text-only PDF barely shrinks. **Strong** turns each page into an image, which makes big savings on scans and image-heavy files. The text in a Strong result is no longer selectable, and Strong has a page limit because every page is redrawn on your device.

### JPG to PDF

Add JPG or PNG images, one image per page, in the order you choose. iPhone HEIC photos are not supported: export them as JPG from the Photos app first.

### Limiting who can open it

These tools change the pages of a PDF. If you want to control who can open the file, upload it and add a password to the link instead (free on every plan). See [Link settings](https://linkinseconds.com/docs/link-settings).
