Conversion FAQs

Frequently Asked Questions

1 Will transparent background areas in my PNG turn black?
No. The renderer handles alpha channels natively. Standard transparent regions are converted to white backdrops within the compiled PDF page wrapper.
2 Can I combine multiple PNG files into one PDF?
Yes. You can upload several PNG images simultaneously, rearrange their layout sequence via drag-and-drop tiles, and merge them into a single PDF document.
3 What is the maximum image resolution allowed?
There is no hard resolution limit. High-resolution screenshots and UI mockups are mapped to vector canvas boundaries without compression or downscaling.
4 Is my private design document secure here?
Yes. Since all conversion routines execute within the browser tab, your graphic layers, screenshots, and visual designs are never transmitted across network servers.
5 Do I need to register or pay to export high-res PDFs?
No. The compiler functions entirely client-side, enabling fast, unlimited image compilations with zero fees, subscriptions, or watermarks.
