How to turn images into a PDF
Drop the pictures onto the panel, or tap it to browse. Each one is listed with its dimensions, and the pages come out in the order shown — use the arrows to move a file up or down. Pick a page size, then press Create PDF.
Fit the image, or a fixed page size
These answer different questions and the right one depends on where the file is going.
- Fit the image makes every page exactly the shape of the picture on it. No borders, no letterboxing, no wasted space. This is what you want for a PDF that will be read on a screen, or for a set of photographs of different shapes.
- A4 or Letter gives every page the same size whatever the pictures are, with each image scaled to fit inside the margin. This is what you want for anything that will be printed, filed or submitted, because a printer handling a document of mixed page sizes will do something you did not ask for.
With a fixed size, Match image orientation turns each page landscape or portrait to suit its picture, which wastes far less paper than forcing a wide photograph onto a portrait page.
Quality: what happens to each format
A PDF can carry JPEG and PNG data directly. That means those two are copied into the document byte for byte — never decoded, never re-compressed, never resized. A ten megapixel photograph in the PDF is the same ten megapixel photograph you started with, and converting the same file twice gives the same result both times.
The other formats are a different story. PDF has no way to hold WebP, GIF, BMP or AVIF, so those are drawn onto a canvas and re-encoded as JPEG on the way in. That step is lossy. It is done at high quality and is usually invisible, but it is a real re-encode and it is worth knowing about if you are working from WebP originals.
| Format | What happens |
|---|---|
| JPG / JPEG | Embedded exactly as-is, no quality change |
| PNG | Embedded exactly as-is, transparency kept over a white page |
| WebP, GIF, BMP, AVIF | Converted to JPEG first — a single high quality re-encode |
| HEIC / HEIF | Most browsers cannot open these at all; see below |
iPhone photos
Recent iPhones capture HEIC by default, and most browsers cannot decode it, so the file simply will not open here or anywhere else on the web. Two ways round it: set Settings → Camera → Formats to Most Compatible so the camera writes JPEG in the first place, or share the photos through Mail or the Files app, which usually converts them to JPEG on the way out.
Why this being local matters here
Look at what people actually convert into PDFs: a photographed passport, a scanned signature page, receipts for a claim, a certificate, a filled-in form. That is a list of exactly the documents you would not want sitting in a stranger's upload directory. Nothing here is transmitted, because there is nowhere for it to go.
Questions
Are my photos uploaded to convert them?
No. The images are read by your browser and written into a PDF there. There is no backend, so nothing is transmitted and nothing is stored. That matters here more than on most tools, because the pictures people convert are usually documents: passports, receipts, certificates and forms.
Does converting reduce the quality of my images?
Not for JPG and PNG. Those are embedded into the PDF exactly as they are, with no decoding and no re-compression, so the picture in the PDF is the file you started with. WebP, GIF, BMP and AVIF have to be converted first because the PDF format cannot carry them, and that step does re-encode.
Should I fit each image to its own page or use A4?
Fit to the image when the PDF is for viewing on a screen: every page matches its picture exactly with no borders. Choose A4 or Letter when it will be printed, so every page comes out the same size and nothing is cropped or scaled unexpectedly by the printer.
Why will my iPhone HEIC photos not open?
Most browsers cannot decode HEIC, and this tool can only use what the browser can open. On an iPhone, setting the camera to Most Compatible makes it capture JPEG instead, or sharing the photo through Mail or Files usually converts it on the way out.
What order do the pages come out in?
The order shown in the list, which is the order you added them. Use the arrows to move a file, or the companion Image to PDF Maker if you want to drag thumbnails around and rotate individual pictures.
Is there a limit on how many images I can convert?
No fixed limit. Everything is held in memory, so the ceiling is the device: a desktop handles a few hundred photographs comfortably, while a phone is happier in batches of a few dozen.
