How to convert PNG to PDF
- Add your files. Drop PNG files anywhere on the page, or use Choose files. Folders and ZIP archives work too; every PNG inside is picked up.
- Check that PDF is selected. PDF is already chosen on this page. Other formats in the same row are one tap away if you change your mind.
- Adjust options if you need to. Choose “fit each image” or A4 pages, and whether to combine the images into one PDF.
- Convert and download. Press Convert. Each file shows its progress, then a Download button. With several files, “Download all” gives you a single ZIP.
What happens to your PNG
Each PNG becomes a page in a PDF built with pdf-lib in your browser. Pages either match each image’s own size or use A4 with the image fitted inside the margins. When you add several PNG files, you can combine them into one PDF in the order shown in the list, or make one PDF per image.
Images are embedded without being re-compressed where the format allows, so the PDF looks the same as the originals. For a PDF that must stay under a size limit for a form, use JPG to PDF under 100 KB.
About PNG and PDF
PNG: PNG is lossless and supports transparency, which makes it the usual choice for screenshots, logos and graphics with sharp edges. Photos saved as PNG are much larger than JPGs.
PDF: PDF keeps a document’s layout fixed on every device, which is why it is used for forms, invoices and anything printed or signed.
Questions
Is my PNG file uploaded anywhere?
No. The conversion runs inside this browser tab using code served by this site, and the PDF is created on your device. You can even disconnect from the internet once the page and its converter have loaded.
Can I put many PNG files into one PDF?
Yes. Add all the images, choose PDF, and keep “Combine into one PDF” switched on. Pages follow the order of the list.
Can I convert several PNG files at once?
Yes. Drop as many PNG files as you like, a whole folder or a ZIP. They convert one after another, and “Download all” saves every PDF in one ZIP that keeps your folder structure.
Is there a file size limit?
There is no fixed limit, because nothing is uploaded. The practical limit is your device’s memory: a phone may struggle with very large files that a laptop converts easily.
