Quick Answer

Add several JPG or PNG images and download a single PDF with one image per page, in the order you added them. Each page is sized to its image's pixel dimensions, and JPGs are embedded without re-encoding, so there is no quality loss. The whole PDF is built in your browser with the pdf-lib library — nothing is uploaded.

What the Image to PDF Does

This packages a set of images into one PDF — handy for turning scanned pages, receipts or photos into a single document you can email or file. Each image lands on its own page.

It is built locally with the pdf-lib library. JPGs are embedded as-is, with their original compressed data, so combining them into a PDF adds no quality loss.

How It Works

Add one or more JPG or PNG images; they are listed in the order you picked them and stay on your device.

On download, each image is embedded into a new PDF page sized to that image's pixel dimensions, in order. A 1000-pixel-wide image makes a page 1000 points wide, since a PDF point is one seventy-second of an inch.

The combined file is saved as images.pdf. Nothing is uploaded.

Processing pipeline

  1. Pick your images. Select multiple JPG or PNG images; they are processed on your device, never uploaded.
  2. Embed each image. Each image is added to the PDF — JPGs without re-encoding, PNGs as they are.
  3. Size each page. Every page is sized to its image's pixel dimensions, kept in the order you added them.
  4. Download the PDF. The combined images.pdf is saved to your device.

Privacy

Your images are combined into the PDF entirely in your browser and are never uploaded — there is no server.

The pdf-lib library runs locally, so the document is assembled on your device and nothing is stored or logged.

No account is needed, and closing the tab leaves nothing behind.

Standards & references

  • pdf-lib — A JavaScript library that creates and edits PDFs in the browser; it embeds JPG and PNG images directly into pages.
  • PDF point — PDF measures pages in points, where one point is one seventy-second of an inch, so a page sized to an image's pixels can be physically large.

Accuracy & Limitations

JPGs are embedded without re-encoding, so they keep their exact original quality inside the PDF. PNGs are embedded as well; the PDF simply carries the image data.

Each page is sized to its image in points, where one point is one seventy-second of an inch. A photo a few thousand pixels wide therefore makes a physically large page — fine on screen, but choose fit to page when printing.

Pages are not normalised to a common size or orientation. A mix of portrait and landscape images gives a PDF with mixed page sizes; there are no margins added.

It accepts JPG and PNG only, and arranges them in the order you added them. There is no reordering or rotation in this tool.

Real-World Use Cases

Scans into one document

Turn a stack of scanned or photographed pages into a single PDF to email or archive.

Receipts and records

Combine receipt photos into one PDF for an expense claim.

Photo set as a file

Bundle a set of images into one shareable, printable document.

Submit a multi-page form

Merge photographed form pages into the single PDF a portal expects.

When to use it — and when not to

Good for

  • Combining several images into one PDF
  • Keeping JPG quality with no re-encoding
  • Turning scans or photos into a document

Not the best choice for

  • A specific paper size like A4 — pages match the images
  • Reordering or rotating pages — add them in order
  • Formats other than JPG and PNG

To merge or reorder existing PDFs, use the merge-PDF or organise-pages tools; for a single image, the JPG-to-PDF tool does the same job.

Frequently Asked Questions

How many images can I combine?
As many as you like, within your device's memory. Each becomes one page in the PDF, in the order you added them.
Does it reduce the image quality?
No. JPGs are embedded without re-encoding, keeping their exact original quality, and PNGs are embedded as they are. Combining images into the PDF adds no compression.
What size are the PDF pages?
Each page matches its image's pixel dimensions, treated as points. Since a point is one seventy-second of an inch, a large image makes a large page. Use fit to page when printing.
What formats can I add?
JPG and PNG. Other formats are not accepted by this tool.
Can I mix portrait and landscape images?
Yes, but the PDF will have mixed page sizes, because each page matches its own image. There is no normalising to one size.
Can I reorder the pages?
They follow the order you added the images. To change the order, add them in the sequence you want; this tool does not reorder afterwards.
Is my data uploaded?
No. The PDF is built entirely in your browser with the pdf-lib library. Your images never leave your device.
Why is my PDF page huge when I print it?
Because the page is sized to the image's pixels in points, which can be large. Set your print dialog to fit to page or shrink to fit.
Does it add margins or borders?
No. Each image fills its page edge to edge, with no margins.
Can it make a single multi-image page?
No. It places one image per page. For a collage on one page you would need a different tool.
How is this different from the JPG-to-PDF tool?
They use the same approach — pdf-lib with image-sized pages. This one is set up to take several images at once and is grouped with the image tools; the result is the same kind of PDF.
What is the output filename?
The combined document is saved as images.pdf.
