Combine Images into a Single PDF
Turn photos, screenshots or scanned pages into one tidy PDF. Arrange the images, choose a page size and margins, and each image becomes one page.
How to convert images to a PDF
- Choose your images (JPG, PNG or WebP) or drag them onto the drop area.
- Put them in page order using the arrow buttons or by dragging rows.
- Pick the page size (A4, US Letter or fit to image), orientation and margin, and optionally a document title.
- Select Create PDF and download the result.
Supported formats
- Input
- JPG, PNG, WebP
- Output
- Maximum size
- 50 MB per file (limited by your device's memory)
How images are placed on the page
With A4 or Letter, each image is scaled to fit inside the margins without cropping or distortion and centred on the page; Automatic orientation turns the page sideways for wide images. Fit to image makes every page exactly the size of its image (treating 96 pixels as one inch) plus the margin. JPG and PNG files are embedded byte-for-byte, so there is no quality loss. WebP isn't supported inside PDFs, so WebP images are converted on a canvas first — to PNG if they contain transparency, otherwise to high-quality JPG. Phone photos with an EXIF rotation flag are straightened automatically. To shrink large photos first, use the Image Resizer; to reverse the process, use PDF to Images.
Benefits
- JPG and PNG are embedded without re-compression, preserving the original quality.
- Rotated phone photos come out upright thanks to EXIF orientation handling.
- Accessible reordering with buttons as well as drag and drop.
Limitations
- Each image is limited to 50 MB and up to 100 images per PDF; very large batches can exhaust memory on phones.
- HEIC, GIF, TIFF and SVG images are not supported — convert them to JPG or PNG first.
- WebP images are re-encoded (PNG or 92% JPG) because the PDF format cannot store WebP.
Privacy and security
Images are decoded by your browser, prepared on a canvas only when needed (WebP or rotated JPEGs), and assembled into a PDF by pdf-lib in a Web Worker. Nothing is uploaded.

Frequently asked questions
Will my photos lose quality?
JPG and PNG images are placed into the PDF unchanged. The page may display them smaller to fit A4 or Letter, but the full-resolution image is kept inside the file, so you can zoom in.
Why is my PDF as large as all my photos together?
Because the images are embedded at their original quality. If you need a smaller file, reduce the photos first with the Image Compressor, or run the finished PDF through the PDF Compressor's strong mode.
Can I mix portrait and landscape images?
Yes. With Automatic orientation each page follows its image, so a landscape photo gets a landscape page and a portrait one a portrait page.
