Image to PDF Converter
Image to PDF converts JPG, PNG and WebP pictures into a single PDF document, one image per page. You can set the page size and orientation, and the images are drawn onto the pages at full resolution rather than being re-compressed, so print quality is maintained.
How to use Image to PDF Converter
- Add one or more images — the order you add them is the page order.
- Choose the page size and orientation that suit the final document.
- Process the images and download the assembled PDF.
Where Image to PDF Converter is useful
- Submitting photographed ID documents as one PDF instead of loose JPEGs.
- Building a simple photo portfolio for printing.
- Turning a set of receipts captured on a phone into a single expense file.
Formats, algorithms and limits
Images are embedded as page-level objects: JPEG data is copied in directly, while PNG and WebP sources are drawn through the canvas. Aspect ratio is preserved, so an image that does not match the chosen page shape is fitted rather than distorted.
Troubleshooting and honest limits
- For archival scans, keep the original image resolution — the PDF embeds the picture, it does not upscale it.
- Use landscape pages for wide screenshots so no content is cut off.
- Sort your files in the file picker before adding them; page order follows your selection.
Frequently asked questions
Can I mix portrait and landscape images in one PDF?
Yes. Each image is fitted to the page shape while keeping its aspect ratio, so you can assemble a portfolio containing both orientations without distortion.
Does converting to PDF reduce image quality?
No. JPEG images are embedded as-is and other formats are drawn at their native pixel dimensions, which is why the PDF is usually about the size of the images combined.
Which image formats are supported?
JPG, PNG and WebP are the reliable formats. GIF and HEIC support depends on whether your browser can decode them — convert those to JPG first if the tool reports an error.
Can I add text or a header to the resulting PDF?
Yes — build the PDF here, then use Add watermark or Header & Footer to stamp text onto every page of the finished document.
