PNG to PDF: help & limits

Transparency is preserved in the PDF image. Most PDF viewers display a white page behind it. Animated PNG is rejected.

Page order follows the list. Use the arrow buttons to rearrange files. Fit on A4 adds space without cropping. Images are rendered using browser color handling; this is not an archival color-preservation tool. Processing stops after two minutes. Combined outputs are limited to 100 MiB.

Processing libraries load from Reqly. File contents stay in browser memory. No server fallback is used. Cancel keeps completed outputs available. Your originals are unchanged.
