How to make a PDF from images
- Add your images: JPEG, PNG, WebP or HEIC. Photos from an iPhone work directly.
- Order them by dragging or with the arrows. The first image is page one.
- Choose the page size (A4, US Letter, or the same as each image), orientation, margin and fit.
- Click Make PDF and download.
Page size, orientation and fit
- A4 / Letter make a document that prints and uploads like any other. Automatic orientation turns the page landscape for landscape photos.
- Same as the image sizes each page to its photo, with no margins, which suits photo books and slides.
- Whole image (fit) shows all of each image inside the margins, leaving white space if the proportions differ.
- Fill the page (crop) fills the area inside the margins, cropping the edges of images whose proportions differ.
- Margin adds white space around each image; 10 mm looks tidy for documents, 0 for photos.
Scanning documents with a phone
Many people use JPG to PDF to turn phone photos of documents into a file for an upload portal. For the best result:
- Photograph in daylight, phone parallel to the page, page filling the frame.
- Use your phone's document scanner mode if it has one (Notes on iPhone, Google Drive on Android). It straightens and crops before you get here.
- Keep pages in order as you shoot, so the photos sort correctly.
- Check every page is legible at 100% zoom before you submit.
File size
Phone photos are large, often 3 to 5 MB each, and the PDF is roughly the sum of its images. Ten photos can easily make a 40 MB PDF, over most portal limits. After making the PDF, run it through Compress PDF in strong mode with a target size; for scanned documents this usually brings it well under 5 MB with no visible loss.
What the PDF contains
Each page is one image. Text in the photos is pixels, not text, so it cannot be searched or selected; that would need OCR (optical character recognition), which this tool does not do. HEIC and WebP images are converted to JPEG inside the PDF, because PDF does not support those formats; PNGs stay lossless.
Orientation of phone photos
Phone photos store their orientation in EXIF data rather than in the pixels. The tool reads it and draws each image upright, so a photo that looks right in your gallery looks right in the PDF. If a page still comes out sideways, the photo's orientation tag is wrong; fix it afterwards with Rotate PDF.
On a phone
This is the most common way people use the tool: photos of documents taken on a phone, turned into one PDF for an upload. Tap Choose images, select the photos in order, check the order in the list, choose A4 and a 10 mm margin, and tap Make PDF. Then compress the result if a portal has a size limit. Everything happens on the phone; the photos are never uploaded.
Mixing photos and scans
Images of different sizes and proportions can go into one PDF. With A4 and "Whole image", each is scaled to fit the page with its proportions kept, so a landscape receipt and a portrait letter both look natural. With "Same as the image", each page takes its image's shape, which is better for photos but makes an irregular document if you print it.
Order and naming
Photos are added in the order you select them; phones usually list them by the time they were taken. If you photographed pages out of order, reorder them in the list before making the PDF; it is quicker than fixing it afterwards. Name the PDF descriptively after downloading, for example lease-signed-2026-10.pdf, so it is easy to find and recognisable to the recipient.
HEIC photos from iPhones
iPhones save photos as HEIC by default. Many websites cannot read HEIC, but this tool decodes it in your browser and stores the image as JPEG inside the PDF, so the result opens everywhere. Nothing is uploaded for the conversion.
Checking the PDF
Open the result and page through it once: every image present, in order, the right way up, and legible at 100% zoom. Check the file size against any upload limit, and compress if needed.
Privacy: the file stays on your device
Online PDF services upload your document to their servers, process it there and keep it for a while. This tool does the work in your browser. The file is read into the page's memory, processed by open-source libraries (pdf-lib for editing and pdf.js for rendering) in a background worker, and the result is offered back as a download. Nothing is sent anywhere, there is no account, and closing the tab discards everything. You can check it: open your browser's developer tools, watch the Network tab while you run the tool, and you will see no upload. After the page has loaded once it also works offline.
