Convert images to PDF, for free

Converting a series of images into a single PDF document is one of the most common ways to digitise an administrative file: gathering photos of proof of address, a bank statement photographed page by page on a phone, or a paper form filled in then photographed, into a single document that's easy to send by email or upload to a website that only accepts one file.

Each image becomes a page

The tool treats each imported image (JPG or PNG) as an independent page of the final PDF. You can import several images at once (multiple selection or drag-and-drop of a whole folder), then reorder their thumbnails to set the exact page order in the generated document — useful when the photos weren't taken or named in the original document's logical order.

Fit to page or native size

Two layout modes are offered. The first keeps each image's exact dimensions as the PDF page size: no margins, no distortion, pixel-perfect to the original photo or scan. The second centres each image on a standard-size page (A4 or Letter), with automatic margins — handy for a consistent-looking document when the source photos have different proportions or resolutions, particularly for printing.

How it works with no server

Conversion relies on pdf-lib to build the PDF document page by page, inserting each image as-is into the file's structure: no recompression is applied, which preserves your photos' or scans' quality. Like the other page-handling tools in this toolbox, everything happens in your browser's memory — your images are never sent to a server, which matters particularly when they contain ID documents or personal information.

Frequently asked questions

Which image formats are accepted?
JPG and PNG are supported directly. For a HEIC photo (common on iPhone), convert it to JPG first with our dedicated tool, before assembling it into a PDF.
Can I combine several images into a single multi-page PDF?
Yes, that's this tool's main use: each added image becomes a page of the final PDF document, in the order you arranged them by drag and drop.
Does the final PDF keep the images' original quality?
Yes: images are embedded in the PDF at their original resolution, with no extra recompression. The final PDF's size is therefore close to the sum of the source images' sizes.
Can I choose the generated PDF's page size (A4, Letter)?
Yes, with a choice between fitting the page size to each image (no margins, no distortion) or centring it on a standard A4 or Letter page, handy for even printing of a batch of photos with different sizes.
Can this tool also extract images from an existing PDF?
No, that's the reverse operation: use the PDF to JPG tool to extract a PDF's pages as images.
Is there a limit to how many images can be combined?
No artificial limit: the practical limit depends on your browser's memory and the images' combined size, generally enough for several dozen high-resolution photos.
