Image to PDF puts one JPG, PNG or BMP picture on an A4 page and gives you a PDF to download. The image is scaled to fit with no cropping or stretching, JPG and PNG files keep their quality, and there's no account.

How an Image Becomes a PDF Page
Image to PDF turns one picture into a one-page PDF: a phone photo of a receipt, a screenshot, a scan someone saved as an image. Upload a JPG, PNG or BMP file and you get an A4 PDF with the image scaled to fit the page.
Lots of forms and learning platforms only take PDF uploads, and a PDF prints at a size you can predict. The converter doesn't need an account, and it doesn't add anything to your page.
Convert Your Image to PDF for FreeHow to convert an image to PDF
- Click Choose Files or drag one JPG, PNG or BMP image onto the page. It can be up to 25 MB.
- Check that the file name shown is the image you want.
- Click Convert To PDF.
- Click Download to save the PDF.
Anything that isn't a JPG, PNG or BMP gets refused with a message before it uploads. For HEIC or TIFF images, pick the converter made for that format.
What the PDF page looks like
The page is A4, which the ISO 216 paper standard defines as 210 × 297 mm. If the image is wider than it is tall, the converter turns the page to landscape; otherwise it stays portrait.
The image is scaled to fill as much of the page as it can and centered, with no margin. It's never cropped or stretched, so an image that's a different shape from the page leaves white space at two edges.
A photo you took sideways on a phone gets turned upright first, using the orientation the camera stored in the file.
Which image formats you can use
JPG photos and PNG screenshots keep their quality
An upright JPG goes into the PDF without being compressed again; only its metadata blocks, such as Exif, a comment and Photoshop data, get cut out. In October 2026 we pulled the picture back out of the PDF made from test.jpg with pdfimages: every pixel decoded the same as the original, and the file was 30,481 bytes instead of 36,488.
A PNG gets unpacked and stored again without loss, so its bytes change but its pixels don't. Our 200 by 150 pixel test.png came back with every pixel equal, and its transparency was kept as a separate soft mask.
The exception is a JPG with a rotation tag. Our 400 by 300 pixel test photo, tagged to be turned a quarter, came out as an upright 300 by 400 pixel JPEG saved again at quality 92 (982 bytes instead of 1,670), so that photo does get compressed a second time.
BMP images are stored without loss
A BMP file goes into the PDF as a lossless PNG image, so every pixel stays the same and the file usually gets smaller.
Other image types
For iPhone photos use HEIC to PDF. A blurry or dark photo stays blurry in the PDF, so take the picture in good light and hold the camera straight above the page.
What happened when we tested Image to PDF
We used test.jpg, a small test photo of 35.6 KB. The tool gave back test_ImageToPDF.pdf, 36.9 KB, with 1 page, 0.1 seconds after we clicked Convert To PDF on our local test server.
There are no options on the page, so the image was converted as uploaded. Tested in October 2026.
Turning several images into one PDF
This tool does one image at a time. For several pictures in one document, use Merge Images to PDF, or JPG to PDF and PNG to PDF, which also let you choose the page size, orientation and margins.

A PDF made from a photo holds a picture of the text, and you can't search it yet. Run it through OCR PDF to add searchable text, and use Compress PDF if a big photo makes the file too large to upload.
Frequently Asked Questions about Image to PDF
Which image formats can I convert to PDF?
JPG (also called JPEG), PNG and BMP. Anything else gets refused before upload.
Can I convert several images into one PDF here?
No. This tool takes one image and makes a one-page PDF. Use Merge Images to PDF to combine several pictures into one file.
Will my image be cropped or stretched?
No. It's scaled to fit an A4 page and centered, so you may see white space at the edges if its shape differs from the page.
Does the PDF lower the quality of my photo?
No. An upright JPG or PNG goes into the PDF unchanged. A JPG that has to be turned upright is saved again at high quality (JPG quality 92).
Can I choose Letter size or add margins?
Not in this tool, which always makes an A4 page without margins. JPG to PDF and PNG to PDF offer Letter size, fit to image and margins.
How long do you keep my image?
Your image and the PDF are deleted automatically within two hours. You don't need an account to use the tool.
