Images to PDF
Turn photos or scans into one document, sized to A4 or to fit.

What images to PDF is
Wrapping photographs or scans in a PDF container. Done correctly the image data is embedded as-is rather than re-encoded, so the picture in the document is bit-for-bit the picture that came out of the camera.
What this tool does that others do not
Embedded, not re-encoded
JPEG and PNG are the two formats the PDF format can embed directly. That means no generational quality loss — and it also means the resulting PDF will be roughly the size of your images added together.
A paper size, or each page the size of its image
A4, Letter, A3 or A5, portrait or landscape, with no margin, a small one or a big one, gives a conventional document for printing or filing; each image is scaled to fit the page and centred. Fit to each image makes every page exactly its image’s pixel size, which is right when the images are already the shape the page should be.
How to use it
Add the images in the order you want the pages
The list order is the page order; add them in batches if you need a particular sequence.
Choose A4 for anything that will be printed
Fit-to-image produces pages of varying size, which is fine on screen and awkward on paper.
Convert other formats first, deliberately
WebP, HEIC and AVIF are not accepted, because they would have to be transcoded and that would lose quality silently.
Worked example
Real input, real figures.
Filing a set of phone photographs of a document
You give it
Eight JPEGs from a phone camera, A4 page size.
You get
An eight-page PDF at roughly the combined size of the JPEGs, with each photograph embedded at exactly the quality it was shot at. Nothing is recompressed, so there is no second generation of loss.
Against a typical image-to-PDF converter
| Aspect | This tool | A typical converter |
|---|---|---|
| Image handling | JPEG and PNG embedded unchanged | Often re-encoded |
| Accepted formats | JPEG and PNG, with the reason for the rest | Everything, transcoded silently |
| Page size | A4 or fit to each image | One fixed size |
| Upload | None | Images posted to a server |
Guide
What it will not do
- WebP, HEIC and AVIF are refused. The PDF format has no native encoding for them, so accepting them would mean an invisible transcode. Convert them first with the image converter and you can see what the conversion cost.
Photographs of paper, turned into paper
JPEG and PNG images are embedded directly rather than re-encoded, so a photo of a document goes into the PDF at exactly the quality it came out of the camera. Choose A4, Letter, A3 or A5 for a conventional document, in either orientation and with or without a margin, or fit each page to its image when the images are already the right shape. Leave Merge all images into one PDF ticked for one document, or untick it for one PDF per image.
WebP, HEIC and AVIF are not accepted: the PDF format has no native encoding for them, so they would have to be transcoded first, which loses quality silently. Convert those with the image converter and bring the results back.
Questions people ask
Straight answers. Each one links directly: copy the address after opening it.
Which image formats work?
JPEG and PNG. Those are the two the PDF format can embed without re-encoding. HEIC from an iPhone, WebP and AVIF have to be converted first — our image converter does that, and doing it as a deliberate step means you can see what the conversion cost rather than having it happen invisibly.
Will the images be compressed again?
No. A JPEG is embedded as the JPEG it already is. That means no generational quality loss, and it also means the PDF will be roughly the size of your images added together.
What order will the pages be in?
The order shown in the list, which is the order you added them. Add them in batches if you need a particular sequence.
Nothing leaves your device
Your file is read into this tab and worked on there. It is never uploaded, which is why there is no queue, no daily limit and no account, and why the tool still works with the network switched off.
