Turning photos into a PDF is the usual way to submit documents you only have as images — a photographed form, a batch of receipts, a scanned ID. One file is easier to send, keeps the pages in a fixed order, and is accepted by systems that reject loose images.
How to use the Image to PDF
- Drop your images onto the upload area, or click to choose them
- Arrange them with the arrows — the order here is the page order
- Pick a page size: fit-to-image for digital use, A4 or Letter for printing
- Click Create PDF and download it
Page size: fit to image, or a standard size
Fit to image makes each page exactly the size of the image it contains. Nothing is cropped and there are no borders, but pages can vary in size, and printing is unpredictable because the page is not a standard format.
A4 or US Letter places each image centred on a standard page, scaled to fit while keeping its proportions. This is what you want for anything that will be printed or submitted to a system expecting a normal document. A portrait photo on a landscape page leaves wide margins at the sides — switch the orientation to match your images.
Margins add white space around the image. Useful for documents that will be printed and hole-punched or bound; unnecessary for digital-only files.
What happens to your images
Every image is re-encoded as JPEG before being embedded, which is how one code path handles PNG, WebP, GIF and BMP alike. Two consequences worth knowing.
Transparency is flattened onto white. PDF pages are opaque, so a transparent PNG background becomes white. If that is wrong for your image, place it on the colour you want before converting.
Very large images are capped at 2600 pixels on the long edge. A 48-megapixel phone photo contains far more detail than any print or screen will show, and embedding it at full size produces an enormous PDF for no visible benefit. The quality setting controls the trade-off for the rest.
If you need genuinely lossless embedding — artwork, diagrams with fine lines, anything that will be enlarged — keep the original files alongside the PDF.
Frequently asked questions
Which image formats are supported?
Anything your browser can display: JPG, PNG, WebP, GIF, BMP and AVIF. Each is re-encoded as JPEG for embedding.
Are my images uploaded?
No. They are read, converted and assembled entirely in your browser. Nothing is transmitted, which matters for photographed IDs and personal documents.
Why did my transparent PNG get a white background?
PDF pages are opaque — there is no transparency to preserve. Transparent areas are filled with white. Composite the image onto your preferred background first if white is wrong.
Will the PDF be searchable?
No. The pages contain images, not text, so there is nothing to search or select. Making a scan searchable requires OCR, which is a separate process.
How do I keep the file size down?
Use the smaller JPEG quality setting, and resize very large photos before adding them. Images are already capped at 2600px on the long edge, which is ample for screen and print.
Can I put several images on one page?
Not with this tool — it places one image per page. Combine the images into a single composite first if you need a grid layout.
