The formats
PNG and PDF at a glance
What is a PNG file?
PNG is a lossless image format, so it keeps every pixel exactly as it was saved. It supports transparent backgrounds, which makes it the usual choice for logos, screenshots, and graphics with sharp edges or text. A photo saved as PNG is often several times larger than the same photo as a JPG. It opens in every web browser, Windows Photos, macOS Preview, iPhone and Android galleries, and editors like Photoshop, GIMP, and Figma.
What is a PDF file?
PDF is the standard format for sharing documents that should look the same everywhere. It fixes the layout, fonts, and images of every page, which is great for reading and printing but makes editing hard. A PDF can contain real text or only scanned pictures of pages. It opens in every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.
Good to know
What changes when you convert PNG to PDF
- Each image becomes one page, in the order you add them. You can drag files to reorder them before converting.
- Photos are embedded as high-quality JPG and graphics with transparency as PNG, so nothing visible is lost.
- Very large images, around 100 megapixels or more, can exceed what the browser allows, especially on phones.
FAQ
Questions, answered
Is this PNG to PDF converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with pdf-lib and Mozilla's pdf.js, so your files never leave your device. Once the page has loaded, it even works offline.
Can I convert several PNG files at once?
Yes. Add as many images as you like, then combine them into one PDF or make a separate PDF for each. Drag them into the order you want first.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in Chrome, Edge, Firefox, and Safari, on computers and phones.
What can open a PDF file?
Every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle images up to about 100 megapixels.
