You have a stack of JPG images — photographs of a document, scanned pages, screenshots, identity documents, receipts for an expense report — and you need them as a single PDF. The task sounds trivial, and it is, but the standard online tools ask you to upload every image to a server before they will produce the output.
That upload step is unnecessary. WorkWithPDF builds the PDF inside your browser, so your images aren't uploaded to our servers. The finished PDF is created on your device and saved to your downloads folder.
This guide covers how to do the conversion, what options you have for the output, and why the local approach is the right default when you are working with images that are even slightly sensitive.
How to Convert JPG to PDF in Four Steps
Step 1 — Open the JPG to PDF tool
Go to the JPG to PDF tool. The tool loads immediately. It's free, with no sign-up and no subscription.
Step 2 — Add your images
Drag one or more JPG or PNG files onto the page, or click the drop zone and choose them from your file picker. You can add as many images as you need, and add more later if you want to sort them first.
Step 3 — Arrange and configure
Your images appear in a list. Use the arrows next to each one to put them in the order you want. Then choose a page size — A4, Letter, or Fit content — and the page orientation, portrait or landscape. Each image goes on its own page.
If your images are mixed sizes, A4 or Letter gives you a consistent page size with each image scaled to fit, while Fit content sizes each page to its image.
Step 4 — Build the PDF
Click Create PDF. The pages are built one by one in your browser. For a handful of images this completes in a second or two. For fifty or more pages it takes a few seconds longer. A progress bar gives you an indication of where the process is.
When the build is done, click Download and the PDF is saved to your device. A copy is also kept in your browser's storage until you clear the workspace — worth doing on a shared computer.
Why the Local Approach Is Better
Image files often contain more sensitive material than people realise. Photos of identity documents, scans of contracts, pictures of invoices, screenshots of messages, medical prescriptions, family records. Every one of these is something you would hesitate to email to a stranger, yet uploading them to a free online PDF tool is effectively the same transaction without the personal relationship.
WorkWithPDF removes that step from the workflow. The tool does the same basic job as a cloud based JPG to PDF converter, using the open source pdf-lib library. The difference is that the processing runs on your computer instead of a remote server. You can verify this by opening the browser Network tab and watching what happens when you build the PDF. No request contains your images.
For casual use with harmless images the difference is small. For anything you would prefer not to share more widely than necessary, the local approach is a simple way to reduce your exposure without sacrificing convenience.
Output Options
The PDF you build is configurable in a few simple ways:
- Page size. Choose A4 or US Letter for a uniform document, or Fit content to match each page to the dimensions of its image. Images are scaled to fit the page, never cropped.
- Orientation. Portrait is the default. Landscape is the obvious choice for wide images or screenshots of spreadsheets.
- Order. Arrange your images in any order before you build the PDF.
- One image per page. Each image gets its own page.
- Image quality. JPG and PNG images are embedded without being recompressed, so they look the same as the originals.

Typical Use Cases
Expense reports. Combine photos of receipts into a single PDF to attach to an expense submission. One document is easier to review than a dozen individual images.
Identity documentation. When a service asks for scans of an ID and a proof of address, bundling them into a single PDF is cleaner than sending separate files.
Scanned pages. If you have photographed a long paper document page by page, turning the images into a PDF preserves the order and makes the document easier to share or archive.
Contract attachments. Signed and scanned contracts often come back as JPGs of each page. A single PDF is standard practice for filing.
Portfolio submissions. Artists, designers, and photographers often need to submit a portfolio as a single PDF rather than a zip of images.
Frequently Asked Questions
How many images can I add at once?
There is no hard limit. The practical constraint is your device memory. On a standard laptop you can comfortably combine a large batch of images.
Will the image quality be degraded?
No. JPG and PNG images are placed into the PDF as they are, without being recompressed, so their quality is preserved. Each image is scaled to fit its page.
Can I add images of different sizes and formats?
Yes. JPG and PNG images are supported, and images of different sizes can be combined. Choose A4 or Letter for a uniform page size, or Fit content to size each page to its image.
What about rotation?
The tool doesn't rotate images for you. Choose portrait or landscape pages, and if a page comes out the wrong way round, fix it afterwards with the Rotate PDF tool.
Is the finished PDF searchable?
No. A PDF built from JPG images is a PDF of images, not of text. If you want searchable text you need optical character recognition (OCR), which WorkWithPDF doesn't offer yet.
Does the tool work on mobile?
Yes. You can select images from your phone's photo library and build a PDF directly on the device, without uploading them to our servers.
