Screenshots stay sharp
Each PNG is placed as it is, not squeezed again, so text in a screenshot stays crisp and transparent parts stay clear over the white page.
Turn screenshots and PNG images into one PDF, a page for each, in the order you choose. Each PNG goes in as it is, with no loss, so the text in a screenshot stays crisp. The PDF is put together in your browser: nothing is uploaded. Free.
How it works
Choose your screenshots or PNG images, in the order the pages should follow.
Each PNG is placed as it is, without being compressed again, on its own A4 page, and the PDF opens in the editor.
Turn or reorder pages if you need to, then download the PDF.
Why GenPDF
Each PNG is placed as it is, not squeezed again, so text in a screenshot stays crisp and transparent parts stay clear over the white page.
A wide screenshot is scaled to the page's width and centred, so nothing is cut off; a tall one is scaled to its height.
Highlight, draw arrows or add text on the screenshots in the editor before you send the PDF.
Questions
Yes. Choose them together; each becomes its own page, in the order you picked them.
Yes. A PNG is placed as it is, not compressed again, so text and lines in a screenshot stay crisp, and transparent parts show the white page. Each picture gets its own A4 page. For photos, see JPG to PDF.
PNG files are lossless, so the PDF is about as big as the images together. Use Compress afterwards to make it lighter.
No: the PDF is built from your PNGs in your browser, and nothing is sent to make it. A page's image is sent only if you later ask to read its words and agree.
