A practical guide

Keep the screenshot set together.

  1. Choose the PNG files and set their page order.
  2. Use original preparation to preserve transparency, then choose page size and margins.
  3. Create the PDF and inspect transparent edges and text.

Try this example

Choose three transparent PNG form screenshots in screen order. Keep original preparation, create a three-page PDF and check that transparent margins look right in your PDF viewer.

Limits and important details

Original mode: 40 images, 40 MiB input, 16 MP per image / 40 MP total; no EXIF correction. Optional preparation: 10 images, 10 MiB each, 40 MiB total, 12 MP per image / 24 MP total before decode, 40 MiB output. Preparation applies browser EXIF orientation and downsizes without upscaling. JPEG is lossy and fills transparency white; PNG preserves transparency. Image size uses prepared dimensions as PDF points. No HEIC or OCR; limits are not a total memory guarantee.

Example
