Combine Images into One PDF (JPG, PNG, WebP)

Add images by choosing them or dropping them on the box, then put them in order. Drag the grip on each row, or use the up and down buttons, which also work from the keyboard. The remove button on a row deletes that page before you create the file. Each image becomes one page of the PDF, in list order.

Page size can be A4, US Letter, or "fit to each image", where every page takes the size of its image at 96 pixels per inch. For A4 and Letter you choose portrait, landscape or automatic, which picks the orientation from each image shape. Margins run from none to 20 mm. Fit inside keeps the whole image visible, while fill the page scales it up to cover the page and crops what falls outside the margins.

The PDF is built in your browser with pdf-lib. JPEG and PNG files are embedded as they are, so there is no extra quality loss and the PDF is not much larger than the images. Other formats, such as WebP, GIF, BMP and AVIF, are redrawn on a canvas and embedded as PNG, which keeps transparency but can be bigger than the original.

Photos from phones are often stored sideways with an EXIF orientation flag. A PDF viewer ignores that flag, so a JPEG with a rotation is redrawn upright first and written as JPEG at 92% quality. Metadata such as GPS location is not copied into the PDF. The document title is set to the file name you choose.

You can combine up to 100 images in one run, each up to 50 MB and 64 megapixels. Images are loaded one at a time while the PDF is built, but the finished file is held in memory, so very large batches of high resolution photos can exhaust the memory of a phone. If the PDF comes out too large for an email limit, reduce the images first with the image compressor or resizer, or use smaller photos.

For scanned documents, A4 with a small margin and "fit inside the page" is a safe default. Choose "fit to each image" when pages have different shapes and you want no white borders added. If one image is damaged, the tool names it so you can remove it and try again.
