Image to PDF

What is Image to PDF?

Image to PDF is a free, browser-based converter that merges multiple JPG and PNG images into one downloadable PDF document. You can keep each image at its original pixel size or normalize every page to A4 or US Letter in portrait or landscape, add uniform margins, and choose whether images fit inside the page (preserving aspect ratio) or stretch to fill it. A multi-image layout places 1, 2, or 4 pictures per page, and you can reorder images by dragging or with arrow buttons before exporting under a filename you choose. It is handy for students, freelancers, and office workers who bundle scanned receipts, photographed documents, screenshots, or design mockups into one shareable PDF without installing software.

How to use Image to PDF

1. Drag and drop your PNG or JPEG images onto the dropzone, or click it to browse and select files (only PNG and JPEG are accepted; other files are ignored).
2. Reorder the queued images by dragging a row's grip handle, or use the up and down arrow buttons; remove any image with the X button.
3. Open Options to pick a page size (Original, A4, or Letter), orientation (Auto, Portrait, or Landscape), and how many images go on each page (1, 2, or 4).
4. Still in Options, set a margin in millimetres, choose Fit (contain to keep aspect ratio, or stretch to fill), and toggle centering.
5. Edit the output file name if you like; the .pdf extension is added automatically.
6. Click Create PDF to assemble and download the combined document, and click any thumbnail to preview a page in a lightbox first.

Frequently asked questions

Which image formats are supported?

Only PNG and JPEG (.png, .jpg, .jpeg) images are supported. Other formats like WebP, GIF, HEIC, or BMP are not accepted and are ignored when dropped.

Can I use A4 or Letter pages instead of the image size?

Yes. Choose Original to size each page to the image, or A4 / Letter with Auto, Portrait, or Landscape orientation. You can also add margins and fit or stretch images to the page.

How do I put several images on one page?

Set 'Images per page' to 2 or 4 in Options. Pages then use a fixed A4 or Letter size (Original falls back to A4 for multi-image layouts) and arrange the pictures in a grid.

Can I reorder or rename before exporting?

Yes. Drag a row by its grip handle or use the arrow buttons to reorder, remove images with X, and type any output file name; the .pdf extension is added for you.

Are my images uploaded to a server?

No. Everything runs in your browser using the pdf-lib library, so your images are never uploaded anywhere and the tool works even offline.
