Frequently asked questions

Does converting keep PNG transparency?

Yes. When the output format is PNG, the transparent background is preserved.

Where is the DPI stored in a PNG?

PNG files store resolution in a pHYs chunk. The converter writes 300 DPI there and sets the matching pixel size.

Is there a file size limit?

Files are processed in your browser, so very large print sizes may be limited by your device's memory.
