Convert PNG to PDF
Drop in your PNGs, put them in order, and download one PDF. The pages stay as sharp as the images, and the whole job happens in this tab.
The pages appear here once you add pictures.
How to use it#
- Drop your PNG files into the box above. Add more at any time.
- Move them into order with the arrows on each row.
- Choose a page size and a margin.
- The PDF is made as you go, so press Download PDF to save it.
Nothing is lost on the way in#
PNG is lossless, and a PDF can store its pixels the same way, so every pixel of a PNG goes into the document unchanged. Text in a screenshot stays crisp, a line in a diagram keeps its hard edge, and zooming in on the PDF shows the same pixels the PNG had.
The flip side is size. A PNG of a photograph can be several times the size of the same photo as a JPG, and the PDF inherits that. If the pictures are photos and the file is too large, turn them into JPGs first with PNG to JPG, or put the photos through JPG to PDF if you still have them as JPGs.
Transparent areas#
A PNG can be partly see-through, and the PDF keeps that. On a white page the clear parts simply show white, so a logo or a diagram with a transparent background looks as it should on screen and on paper.
If you would rather the clear parts were a colour, such as a brand colour behind a logo, fill them in first with add background to PNG and bring the result back here. The margin around the picture is always the plain page.
Screenshots and page size#
Fit the image makes each page the size of its PNG, one point per pixel. A screenshot 1920 pixels wide becomes a page about 27 inches wide, which reads well on screen, where viewers zoom to fit, and gives the printer a scale to choose.
For anything headed to paper or to a form that expects a normal document, choose A4 or US Letter. Each screenshot is then scaled down to fit inside the margin, and a wide one turns the page to landscape so it keeps a readable size.
Frequently asked questions#
Are my PNGs uploaded anywhere?
#
No. The PDF is built in this tab by your own browser, and nothing is sent to a server. A screenshot often shows more than you meant to share, such as an inbox, an account number, or a chat, so that matters.
Does converting PNG to PDF lose quality?
#
No. The pixels of each PNG are stored in the PDF without any lossy compression, so the page looks exactly like the image. Nothing is smoothed or sharpened.
Will the text in my screenshots be selectable?
#
Not straight away. A screenshot is a picture of words, and it stays a picture inside the PDF. To make the words searchable and selectable, run the finished PDF through PDF OCR, which reads the text and lays it invisibly over each page.
Can I combine several PNGs into one PDF?
#
Yes. Drop in as many as you like, all at once or a few at a time, and each becomes a page in the order shown in the list. The arrows on each row move a page up or down, and the number in front of its name is its page number.
Why is the PDF bigger than I expected?
#
Because the PNGs are. A PDF of PNG images is roughly the size of those PNGs added together, sometimes a little more. Screenshots of text are small, while PNG photographs are large; converting the photos to JPG first is the way to shrink them.
Can I mix PNGs with JPGs or iPhone photos?
#
Yes. JPG, HEIC, WebP, GIF, and AVIF go in the same list, and each becomes a page in the order shown. JPGs are kept as they are, and the other formats are converted to JPEG, since a PDF cannot hold them.
How do I turn the PDF back into PNGs?
#
Use PDF to PNG, which draws each page as a lossless PNG at the detail you choose.
