FAQs About Our PNG to PDF Converter
Below are some common questions about turning PNG images into PDF.
Why convert PNG to PDF online?
Going from .png to .pdf gives you a fixed, easy-to-share document instead of a loose image file. It's useful for combining several images into one file, sending something that looks the same on every device, or archiving visual content alongside other documents.
Will converting my PNG to PDF reduce the image resolution or quality?
No, Lumr's PNG to PDF converter keeps your image at its original resolution, so the picture inside the finished PDF looks just as sharp as the PNG file you uploaded, with no extra compression applied.
How does the converter handle the background transparency of PNGs?
PDF pages don't support transparency the way PNG images do, so any transparent areas in your PNG will typically appear with a solid background once converted. If your image relies on a transparent background, keep this in mind before converting.
Can I combine multiple PNG images into a single PDF document?
Yes, you can upload more than one PNG, and Lumr will combine them into a single PDF, with each image placed on its own page in the order you add them, so you end up with one document instead of several separate files.
Do I need to install any software to turn PNGs into PDFs?
No matter whether you need to convert a PNG file to PDF for one image or several, Lumr's converter works entirely online through any modern web browser: there's nothing to download or install.
Can I use this PNG to PDF converter on my mobile phone?
Lumr's converter works on any device, so you can convert a PNG to PDF from your phone just as easily as from a desktop computer, with no app to download or install.
Is it safe to upload my PNG images to Lumr?
Yes, Lumr converts your images using encrypted processing and doesn't retain your files once you've downloaded the finished PDF, so your content stays private from the moment you upload it to the moment you download your file.
Is there a maximum file size limit for uploading images?
Yes, you can upload image files up to 50 MB, which covers the vast majority of PNGs, including higher-resolution graphics.
