# JPG to PDF converter

https://flaghand.com/jpg-to-pdf makes photos (JPG, PNG, WebP, or any photo the browser opens) into one PDF, a page
each, in the order added; pages can be moved or removed. A JPEG goes into the PDF as its own bytes, not compressed
again; any other photo, or a phone JPEG stored on its side, is saved as a JPEG at quality 0.92 first (at most 6000
pixels on its longest side). Page sizes: Photo (each page its photo's shape, the long side 297 mm), A4, Letter (both
turned sideways for a wide photo), or 4:5 (1080 × 1350, a LinkedIn carousel slide), with no margin or a small one; the
photo is fitted whole and centred. The PDF is checked against LinkedIn's document post: up to 100 MB, 300 pages, every
page the same size.

Free, no sign-up. It runs in your browser: nothing you type or add is uploaded or stored, and there is no API.

## How to use it

1. Drop, choose or paste photos.
2. Move or remove pages, and pick the page size and margin.
3. Download the PDF.

An agent can preset the choices in the link's hash, which never reaches a server (photos can't travel in a link):
https://flaghand.com/jpg-to-pdf#page=portrait&margin=small
Fields: page=photo|a4|letter|portrait, margin=none|small.

## Questions.

### How do I convert JPG to PDF?

Drop the photos on the page, or choose them. Each becomes a page, in the order you added them. Move or remove pages, pick the page size, then choose Download PDF.

### Is my photo uploaded?

No. The PDF is made in your browser. Your photos are not sent anywhere or stored, and the page sets no cookies.

### Does converting lower the quality?

Not for a JPEG: its own file goes into the PDF as it is, not compressed again. A PNG, WebP or a phone photo stored on its side is saved as a high-quality JPEG first.

### How do I put several photos into one PDF?

Drop them all at once, or add more later; each is one page. The arrows under a page move it earlier or later.

### What page size should I pick?

Photo gives each page its photo’s shape. A4 and Letter fit each photo on a paper page, turned sideways for a wide photo. 4:5 is the 1080 × 1350 shape of a LinkedIn carousel slide.

### Can I post the PDF on LinkedIn?

Yes, as a document post, which LinkedIn shows as a carousel. It takes up to 100 MB and 300 pages, and every page should be the same size: pick A4, Letter or 4:5 if your photos’ shapes differ.

To write a carousel’s slides from text instead, use the [LinkedIn carousel maker](https://flaghand.com/linkedin-carousel-maker). Every network’s photo sizes are in the [social media image sizes guide](https://flaghand.com/docs/guides/social-media-image-sizes).

## Flaghand

A PDF goes into a Flaghand draft as a LinkedIn document post, which the owner approves before it goes out.

Flaghand is X and LinkedIn posting for AI agents: your agent drafts through Flaghand's API, CLI or MCP server, you
approve the exact preview with your passkey, and Flaghand posts exactly that.
Sign up at https://app.flaghand.com/start. In a chat app, add the connector at https://app.flaghand.com/mcp: its sign-in page creates the account. An agent with a shell can start the sign-up for its person over HTTP (https://flaghand.com/llms.txt, Quickstart).

For agents: https://flaghand.com/llms.txt (this site) and https://app.flaghand.com/llms.txt (the product's agent guide).
