Frequently asked questions
Does PNG quality survive the conversion?
Yes. PNG images are embedded losslessly — text in screenshots stays exactly as sharp as the original.
What about transparent backgrounds?
Transparent areas are rendered white on the PDF page, which is what printers expect.
Can I mix PNG with JPG files?
This tool accepts PNG only; use Image to PDF for mixed batches — same options, same output quality.
Will the PDF be huge for many screenshots?
The PDF is roughly the sum of your PNG file sizes. For email limits, downscale the screenshots before converting.
Do you compress or optimize my images?
No. Files are embedded as-is; nothing is recompressed or resized behind your back.
Is the conversion uploaded anywhere?
No. Everything happens locally in your browser.
