How to use it
- Drop your JPG, PNG or WebP images onto the box below.
- Pick a page size, and reorder the list if the pages should run differently.
- Press Process files and download images.pdf.
Image size or A4
Image size makes each page exactly as large as the picture on it, measured at 72 dots per inch, so nothing is scaled and nothing is cropped. That suits screenshots and anything that will be read on a screen. The A4 options scale each image to fit inside a standard sheet and centre it, which is what you want when the file will be printed or filed next to other A4 documents. Either way you can add a 10 mm margin, which keeps content clear of the unprintable strip at the edge of most printers.
Photographs keep the right way up
A phone records which way it was held in an EXIF tag rather than by rotating the pixels, and a PDF has no idea such a tag exists. So the tag is read first: a photograph that is already upright is embedded byte for byte with no re-encoding at all, and one that needs turning is decoded with the rotation applied and written once. Sideways holiday photos are the single most common complaint about tools that skip this step.
Why WebP is converted first
A PDF can carry JPEG and PNG image data directly, which is why those two are embedded untouched, but it has no way to store WebP. Every WebP is therefore re-encoded on its way in: to PNG when the image has transparent pixels, so a logo keeps its transparency, and to JPEG when it does not, because a photograph stored as PNG can be many times larger for no visible gain.
Questions
Will the text in my screenshots be searchable?
No. The pages hold pictures of text, not text. There is no character recognition here, so nothing in the PDF can be selected or searched.
What order do the pages come out in?
Exactly the order of the file list, top to bottom. Move any image with the up and down arrows, which work from the keyboard as well as the mouse.
Why is the PDF bigger than my images were?
JPG and PNG files are stored as they are, so the growth is only the document structure around them. WebP images grow more, because they are re-encoded into a less efficient format.
