PNG to PDF
Combine screenshots and PNG scans into one PDF without compressing them again: the PNG data goes into the PDF as it is. The images never leave your device.

How it works
- Drop your PNG images anywhere on this page.
- Put them in order, then choose the page size, the margins and one PDF or one per image.
- Download the PDF.
Screenshots and scans into one PDF
The common case is a pile of phone screenshots (a chat, an order confirmation, a bank transfer) that has to be sent as one document, or PNG pages from a scanner app that you want in a single file. Drop them in, put them in order with the arrows, and every image becomes one page. Up to 100 PNGs of up to 100 MB each fit in one run, and the PDF is built on your device, so screenshots of private conversations are never uploaded.
Page size, orientation and margins
Auto makes each page exactly the size of its image, so nothing is cropped or padded and a tall phone screenshot stays tall. A4 or Letter is for documents that will be printed or that a form expects in a standard size: the image is scaled to fit the page and centered. Orientation follows each image unless you force portrait or landscape, and you can add a small margin or none. One PDF per image (ZIP) is there when each screenshot must be its own attachment.
Good to know about size and quality
The PNG data goes into the PDF unchanged, so the file is roughly as large as the sum of the images and looks exactly like them. If an upload limit bites, run the images through Compress image first, or the finished PDF through Compress PDF. Transparent areas stay transparent, which is what you want for a logo page but not for a screenshot taken over a dark theme: those simply show the white of the page.
Why people use it
Free, no account
Every tool is free, with no sign-up, no e-mail address and no limit on how often you use it.
Your files stay on your device
The browser opens the file and processes it in memory, on your device. Nothing is uploaded, so nothing can be kept, leaked or looked at.
No watermark
The result is yours as it is: no watermark, no branding, no trial version.
Any device
A phone, a tablet or a computer with a current browser is enough: no app to install, no software to update.
Works offline after the first visit
The browser keeps the pages and their engines, so a tool you have opened once keeps working without a connection.
Open-source engines
The code that does the work is open-source software, named on the Licences page, running as WebAssembly in your browser.
Why it is private
Everything you type or drop here is handled by your browser, on your device. Nothing is uploaded. To verify, open your browser's developer tools, go to the Network tab, and use the tool: you will see no request carrying your data.
While a file is being processed, the counter under the result shows the page's network traffic: 0 requests and 0 B for your data.
How to check it yourself, step by step
What you can check yourself
Open your browser's developer tools on the Network tab before you drop a file: while the tool works you will see no request carrying your data, and the counter under every result shows the page's own measurement.
The site sets no cookies, so there is no cookie banner. Anonymous usage counts and error reports without file names are the only things that leave the page, as the privacy policy describes.
Every change goes through thousands of automated tests in three browser engines, including a guard that fails a test if a single byte of a file leaves the page.
Frequently asked questions
- Is the image quality reduced?
- No: nothing is downscaled. An ordinary PNG is placed in the PDF with its own compressed pixel data, untouched, and a transparent one is stored again without loss. The rare 16-bit or interlaced ones are decoded and stored again as PNG, also without loss.
- Is transparency kept?
- Yes. Transparent areas stay transparent in the PDF (as a soft mask), so they show the white of the page, or whatever lies behind them when the page is placed in another document.
- What about JPG and other images?
- Use JPG to PDF: it takes JPG, PNG, WebP, HEIC and more into the same PDF.
- Is anything uploaded?
- No. The PDF is built with pdf-lib in your browser; the images never leave your device.
- Can I turn screenshots into a PDF on my phone without an app?
- Yes. Open the page in the browser, pick the screenshots from your gallery, order them and download the PDF; nothing is installed and nothing leaves the phone.
- How many PNG images can go into one PDF?
- Up to 100 per run, each up to 100 MB. They are placed in the order shown in the list, which you can change before converting.
- Why is the PDF as large as my images?
- Because the images are stored in the PDF as they are, without recompression; that is also why the quality is identical. Compress the images first or the PDF afterwards if you need a smaller file.
- Can I get one PDF for each image?
- Yes. Choose One PDF per image and you get a ZIP with a single-page PDF for every PNG, named after the image.
- Can I change the page order after the PDF is made?
- Yes: open the result in Organize PDF, drag the pages and download again. The images are copied as they are, without losing quality.
Install it as an app
Chrome, Edge and Android browsers offer to install this site from the address bar or the menu; on iPhone use Share, then Add to Home Screen. It opens like an app, keeps working offline and still processes everything on your device.
