Good to know
WebP images are converted to PNG in the browser before embedding; very large WebP files may require additional memory.
How it works
Select one or more JPG, PNG, or WebP images from your device using the file picker.
Each image is read into browser memory — no data leaves your browser.
pdf-lib embeds each image into a new page, scaled to fit the chosen page size (A4, Letter, or original image dimensions).
You can reorder the images before generating the PDF.
The finished PDF is offered as a download directly from your browser.
When to use this tool
Collecting a series of scanned receipts (JPG/PNG) into one PDF for an expense report.

Frequently asked questions
How is this different from other online PDF tools?
Most online PDF tools send your files to a remote server for processing. This tool processes everything locally in your browser using client-side JavaScript. Your files are never transmitted to any server, which means your document content stays entirely under your control.
Are my PDF files uploaded?
No. Your files are read directly by your browser. Your files are never transmitted over the network. The tool works entirely within the browser tab you have open.
Can I verify that files are not uploaded?
Yes. Open your browser's developer tools (F12), go to the Network tab, and watch for any outgoing requests while using the tool. You will see no file data leave your browser. The site may record an anonymous page-view count, which never includes your files and can be disabled.
Does this tool work offline?
Yes, once the page has loaded the tool processes your files entirely in your browser; tool functionality needs no network connection. You can disconnect from the internet and continue using it.
What happens when I refresh the page?
Because nothing is stored on a server, refreshing the page clears your current session. Any files you had selected will need to be selected again.
Does this tool store my files?
No. Files are held in browser memory only for as long as the page is open. Closing or refreshing the page discards them. Nothing is written to disk by the tool, and nothing is sent to a server.
Can this tool unlock password-protected PDFs?
No. This tool does not attempt to remove or bypass PDF password protection. If you know the password, the Unlock PDF tool on this site can remove it locally; then this tool can process the file.
What technologies does this tool use?
This tool uses client-side JavaScript and pdf-lib to embed images into a new PDF document entirely within your browser.
Does this tool use WebAssembly?
No. This tool uses client-side JavaScript and pdf-lib for local PDF structure editing. No WebAssembly is involved.
How do I combine several images into one PDF?
Pick your JPG, PNG, or WebP images with the file picker (or drop them in), use the up and down arrows beside each thumbnail to set the order, choose Fit to image or A4 as the page size, then click convert and save the finished PDF. Every step runs locally in your browser, so the images are never sent anywhere.
What is the difference between the Fit to image and A4 page size options?
Fit to image makes each page exactly match the source image's pixel dimensions, so the picture fills the page edge to edge with no borders. A4 puts every image on a standard A4 page, scaling it to fit while keeping its aspect ratio and centering it, which is handier when you plan to print.
Why are my HEIC phone photos rejected, and how is a sideways photo handled?
This tool accepts JPG, PNG, and WebP images, so HEIC or HEIF files from some phones need to be converted to JPG or PNG first. For photos that carry an EXIF orientation flag, the rotation is baked into the pixels before embedding so the page appears upright rather than sideways, all handled locally in your browser.
Does the Images to PDF converter cost anything to use?
Converting your JPG, PNG, or WebP images into a PDF is completely free — no account, no sign-up, and no cap on how many images or batches you process, and it always will be. Every step, from arranging image order to embedding each photo into a PDF page, runs entirely inside your browser, so your images are never sent anywhere or seen by anyone else.
