Convert images to PDF
Got a mix of photos, screenshots and iPhone pictures? Drop them in together and get one PDF, with each image on its own page. JPG, PNG, WebP and HEIC all work in the same file, and everything runs in your browser, so your images stay on your device.
How to convert images to PDF
Mixed formats in one PDF
Pictures for one job rarely come in one format. Photos from an Android phone are usually JPG, iPhone photos are often HEIC, screenshots are PNG, and images saved from websites are often WebP. This tool takes all four in the same batch and puts them into one PDF, one image per page, so there is nothing to convert first.
Each format is handled in the way that suits it. PNG images are placed in the PDF as they are, keeping every pixel and any transparent parts. JPG, WebP and HEIC images are saved as JPEG inside the PDF at a high quality setting, and photos are turned the right way up using the rotation the camera recorded. HEIC photos are decoded in your browser first, so the PDF itself contains no HEIC and opens anywhere.
Pages follow the order in which the files arrive, and the tool cannot move them around afterwards, so number the file names if the order matters. If a file cannot be read as an image, it is skipped with a short note, and the rest still go into the PDF.
Scan documents with your phone and turn the photos into a PDF
You do not need a scanner to send a paper document as a PDF. Lay each page flat in good light, take a photo from straight above with the whole page in the frame, and you have the raw material for a scan. A dark table under white paper helps the edges of the page stand out.
Then open this page in the browser on your phone, choose A4 or Letter, and add the photos. Each photo becomes one page, scaled to fit inside a 1 cm margin and centered, so the PDF prints on a normal sheet without anything cut off. A photo that is wider than it is tall gets a landscape page, because the page turns to match the picture, not the text in it. If a page comes out sideways, the PDF editor can turn it.
The tool does not crop, straighten or clean up the photos, so each page shows the picture exactly as you took it. Crop the photos first if the table or your fingers are in the shot.
Make the PDF small enough to send
A PDF made from images is roughly as large as the pictures in it, and a photo straight from a phone is often several megabytes. A PDF of ten photos can easily be too big for an email or an upload form.
For screenshots and other PNG images, shrink the files before you convert them. PNG images go into the PDF as they are, so a smaller PNG gives a smaller PDF, and the image compressor handles a whole batch of them. Photos are different: JPG, WebP and HEIC are saved again as JPEG when the PDF is made, so compressing them first gains little. For photos, use resize image before converting to cut the number of pixels, or compress the finished file.
Compress PDF does that in your browser too. Its Balanced level limits every image to 2,000 pixels on the longest side, which keeps a photographed page easy to read, and Strong goes down to 1,400 pixels for the smallest file. The size of the new PDF is shown before you download it, so you can check it against the limit you have to meet.
