Frequently Asked Questions

Will my PNG images lose quality?

No. Each image is placed on its own page at its original resolution and proportions, so nothing looks distorted or compressed.

Does PNG transparency get preserved?

PDF pages do not support true transparency, so transparent areas in your PNG are filled with white in the resulting PDF page.

Can I combine multiple PNGs into one PDF?

Yes. Upload as many PNG files as you need and they will be combined into a single PDF, one image per page, in the order you set.

Is there a file size or file count limit?

Each file can be up to 50MB, and you can upload up to 50 files in a single batch.

Is it safe to upload images with personal or business information?

Yes. Uploads happen over an encrypted connection, and both the source images and the resulting PDF are automatically deleted from our servers after processing.

Is PNG to PDF free to use?

Yes. There is no cost, no subscription, and no account required.

Can I convert PNG to PDF on my phone?

Yes, the tool is fully responsive and works in any modern mobile browser on iOS and Android.

Do I need any software installed to use this tool?

No. Conversion happens entirely in your browser and on our servers, so nothing needs to be installed on your device.
