Image to PDF
Combine images into one PDF - free, in any order.
Your images are combined into a PDF inside this page. They are never uploaded.
What this tool does
Add your JPEG or PNG images, reorder them with the up and down buttons, choose whether each page should fit its image exactly or use a standard page size, and download one PDF with each image on its own page.
Combines any number of JPEG or PNG images into a single PDF, one image per page, in the order you arrange them.
Offers a page size that fits each image exactly (no white borders), or a standard A4/Letter page with the image centered and scaled to fit.
Embeds each image directly with pdf-lib's native JPEG/PNG embedding rather than re-encoding it through a canvas, so image quality is preserved exactly as uploaded.
Lets you keep adding images after the first batch - new files are appended to the same reorderable list instead of replacing it.
How to use it
- Add your images.
- Reorder them if needed, and choose a page size.
- Download the PDF.
Why use this tool
Photos and scans are easier to share as one PDF, and doing it in an editor is slow. Choosing the order and page size gives a tidy document.
Why we built it
We built the image to PDF tool with the same list-then-arrange approach as merge PDF, so you can reorder pictures before building. Compress pictures first with the image compressor and combine with other PDFs using merge PDF.

Who this tool is for
- People turning photos or scans into one document
- Students submitting homework
- Sellers and admins assembling receipts
When to use it
- Making a PDF from phone photos or scans.
- Combining receipts or notes.
- Preparing documents for an application.
- Creating a portfolio.
Why 'fit to image' avoids the usual white-border problem
Forcing every image onto a fixed page size often adds unwanted borders.
Placing a photo that isn't the same shape as A4 or Letter onto one of those fixed page sizes leaves either the image stretched out of proportion, or - the more common choice - scaled down to fit with visible white space on two sides. Making each page exactly the size of its own image sidesteps this: there's no fixed shape to fit into, so no borders and no distortion, which is usually what someone combining photos into a PDF actually wants. The fixed-page options are still there for when a standard page size genuinely matters, like printing.
How 'fit to each image' actually sizes the page
The no-border page size is derived directly from the image's own pixel dimensions.
In 'Fit to each image' mode, the PDF page is created with pdf-lib's addPage() using the embedded image's pixel width and height directly as the page's width and height in points. That's a genuine one-to-one mapping, not a resize: a 4000x3000px photo becomes a page that is literally 4000x3000 points, which works out to a physically large page dimension (about 55x41 inches) even though it displays perfectly normally on screen or when printed at 'fit to page'. It's a detail that only matters if you try to print the result at true (100%) scale rather than letting the printer fit it to paper.
What you give it, and what you get back
| Item | Details |
|---|---|
| Input | JPEG or PNG images. |
| Options | Order and page size: fit to image or A4/Letter. |
| Output | One PDF with one image per page. |
Issues you may run into
| What you see | Why it happens | What to do |
|---|---|---|
| Image not accepted | Only JPEG and PNG are supported. | Convert it first. |
| File is large | Photos are high resolution. | Compress the images first. |
| Transparent area looks different | PNG transparency is embedded as is. | Add a background first. |
Assumptions and limitations
- Only JPEG and PNG images are supported as input.
- A PNG's transparency isn't preserved specially - it's embedded as-is, so a transparent area will show through as whatever a PDF viewer renders behind a transparent PDF image, typically white.
Frequently asked questions
How do I combine images into one PDF for free?
Add your images, reorder them if needed, choose a page size, and download the combined PDF.
Can I change the order of the images?
Yes - use the up and down buttons next to each image to arrange them into the order you want the pages to appear in.
Will my images have white borders around them?
Only if you choose the A4 or Letter page size option - 'Fit to each image' sizes every page exactly to its image with no borders.
What image formats are supported?
JPEG and PNG.
Are my images uploaded anywhere?
No. The PDF is built entirely in your browser - your images are never sent to a server.
Does converting to PDF reduce my image quality?
No - each image is embedded into the PDF using pdf-lib's native JPEG/PNG embedding without any re-compression, so quality is preserved exactly as uploaded.
Can I add more images after I've already added some?
Yes - use 'Add images' again at any time; new files are appended to the existing list and can be reordered or removed just like the ones already there.
