PNG to PDF Converter
Transform single or multiple PNG images into a professional PDF document while maintaining image quality, layout, and clarity.
What Does This PNG to PDF Converter Do?
This tool turns one or more PNG images into a single downloadable PDF, entirely inside your browser. Drop in your files, drag the thumbnails into the order you want, then choose a page size, orientation, and margin before clicking Convert to PDF. A progress bar tracks the conversion, and a Download PDF button appears once the file is ready.
How to Convert PNG to PDF Online
- Upload your PNG files. Drag and drop one or several PNG images onto the drop zone, or click Browse Files to pick them from your device.
- Review the image cards. Every file you added loads as a thumbnail with its name, file size, and a badge showing its current page number.
- Reorder the pages if needed. Press and drag any card to a new position in the grid to change the order the images will appear in the final PDF.
- Remove or add images. Hover a card and click the small remove icon to drop a file, or use Add More at any time to bring in additional PNGs.
- Set your page options. Pick a page size (Auto, A4, Letter, or A3), an orientation (Auto, Portrait, or Landscape), and a margin (None, Small, Medium, or Large) from the toolbar.
- Click Convert to PDF. A loading overlay with a progress bar shows each image being processed one by one until the document is complete.
- Download the finished file. Once the success banner appears, click Download PDF to save the converted document to your device.
Built-In Features
Drag and Drop Upload
Drop multiple PNG files onto the upload area at once, or browse for them manually. Any file that is not a PNG is flagged and skipped automatically, so you can upload only the files you need.
Drag to Reorder Pages
Every thumbnail can be dragged into a new position, and the page number badge on each card updates instantly so you always know the final page order before converting.
Page Size and Orientation Control
Choose Auto to build each page around its image’s own dimensions, or lock every page to a standard A4, Letter, or A3 size with Portrait, Landscape, or Auto orientation.
Adjustable Page Margins
Pick from None, Small, Medium, or Large margins to control how much white space sits around each image on the page, with the image centered inside the available area.
Progress Tracking on Convert
A loading overlay reports which image number is currently being processed and fills a progress bar as the pages are added, so you know how far along the conversion is.
Browser-Based, No Sign-Up
Your PNG files are read and assembled into a PDF locally in your browser, quickly and securely. Nothing is uploaded to a server, and no account or installation is required.
Auto Page Size vs Standard Page Size Explained
The Page Size dropdown gives you two very different ways to lay out your PDF, and picking the right one depends on what you plan to do with the file afterward.
Auto (Fit Image)
Each page is built to match the exact pixel dimensions of its own image, plus the margin you chose. This keeps every screenshot, graphic, or photo at its natural shape without any empty space around it.
A4, Letter, or A3
Every page is forced to the same fixed size, and each image is scaled down to fit inside it while keeping its proportions. This is the better choice when the PDF needs to be printed or added to a document that expects a consistent page size and a clean, professional overall appearance.
When a fixed page size is selected, orientation can be left on Auto so wide images automatically land on a landscape page and tall images land on a portrait page, without you needing to check and set each one by hand.
Common Reasons to Convert PNG to PDF
Bundling Screenshots
Turning a series of PNG screenshots into a single PDF makes them far easier to email, review, or attach to a support ticket than sending each image separately.
Submitting Scanned Documents
Scanning apps often save each page as a separate PNG file. Combining them into one PDF keeps the pages in order and matches what most application forms expect.
Sharing Design Mockups
Designers exporting mockups or UI screens as transparent PNGs can gather every screen into one ordered PDF to walk a client or teammate through a full flow.
Preparing Files for Printing
Print shops generally expect a single PDF rather than a folder of loose images, so converting your PNGs first with a standard page size avoids formatting surprises at the counter.
Useful Tips
Arrange Pages Before Converting
Drag your cards into the correct reading order first. It is much faster to reorder thumbnails than to fix page order once the PDF has already been generated.
Match Margins to the Purpose
Use a small or no margin for screenshots you want to fill the page, and a medium or large margin for documents that will be printed and need room for binding or notes.
Have JPG Files Instead?
This tool only accepts PNG images. If your files are JPG or JPEG, our JPG to PDF Converter follows the same drag, arrange, and convert workflow.
Combining Several PDFs Later
If you convert your PNGs in separate batches and end up with more than one PDF, our Merge PDF tool can join them into a single file afterward.
How to Convert PNG to PDF Without Installing Software
Desktop programs that convert images to PDF usually need to be downloaded and installed before you can use them, and some only work on a specific operating system. This tool skips that step entirely. Open the page in Chrome, Edge, Firefox, or Safari, drop in your PNG files, choose your page settings, and download the finished PDF, all inside the same browser tab.
Because the conversion runs in the browser rather than in an installed application, it behaves the same way on Windows, Mac, Linux, or a Chromebook, so there is nothing to check for compatibility beforehand.
Does Converting PNG to PDF Reduce Image Quality?
A common worry when combining images into a document is that the conversion will blur or compress them. With the Auto page size, each page is built to match the image’s own pixel dimensions, so nothing is stretched or squeezed to fit a different shape. With a fixed page size like A4, Letter, or A3, the image is scaled down proportionally to fit inside the page and margins, the same way a photo shrinks to fit a picture frame without being cropped or distorted.
Because the tool works directly from your original PNG files rather than a lower-resolution preview, the sharpness of screenshots, scanned pages, and graphics carries over cleanly into the final PDF.
Frequently Asked Questions
How do I convert PNG to PDF online for free?
Upload your PNG files using the drop zone or Browse Files button, arrange them in the order you want by dragging the thumbnails, choose a page size, orientation, and margin, then click Convert to PDF and download the file.
Is this PNG to PDF converter free to use?
Yes. The tool is free to use and does not require an account or sign-up.
Can I convert multiple PNG images into one PDF?
Yes. You can upload several PNG files at once, and each one becomes its own page in the same PDF document, in the order shown in the grid.
Can I change the order of the pages before converting?
Yes. Press and drag any image card to a new position in the grid, and the page number badge on each card updates automatically to reflect the new order.
What is the difference between the Auto page size and a fixed page size like A4?
Auto builds each page around the exact dimensions of its image, while A4, Letter, or A3 forces every page to the same fixed size and scales each image to fit inside it.
What does the margin setting do?
The margin setting adds empty space around the image on each page. You can choose None for no border, or Small, Medium, or Large for progressively more white space.
Can I remove an image after uploading it?
Yes. Hover over any image card and click the small remove button in the corner to drop that file from the conversion.
Can I add more images after I have already uploaded some?
Yes. Click Add More at any time to select additional PNG files, which are appended to the existing set of thumbnails.
Does this tool accept file types other than PNG?
No. Only PNG files are accepted, and any other file type you try to upload is rejected with an on-screen message.
Is my PNG file uploaded to a server?
No. The images are read and assembled into a PDF entirely inside your browser. They are never uploaded or stored anywhere.
Is it safe to convert sensitive or personal images with this tool?
Yes. Since the files never leave your device, converting images with personal or sensitive information carries no more risk than opening them locally.
Can I convert PNG to PDF on my iPhone or Android phone?
Yes. The tool works directly in your mobile browser with no app to install. Tap Browse Files to select PNGs from your phone, arrange them, then download the finished PDF.
Does converting to PDF reduce the image quality?
The images are placed into the PDF at their scaled display size for the page settings you chose. For most everyday uses like screenshots and scanned pages, the result stays clear and sharp.
Is there a limit to how many PNG files I can convert at once?
No. You can upload and convert as many PNG files as you need in a single PDF, whether that is one image or a large batch.
What is the downloaded PDF file named?
The downloaded file is named converted followed by a timestamp, so each conversion produces a uniquely named PDF.
