How it works
Screenshots of a form, exported diagrams and scanned pages saved as PNG often need to go out as a single PDF. Add the images, put them in order, and each becomes one page. PNGs are embedded losslessly, so text in screenshots stays razor sharp; JPG, WebP, HEIC and other formats can be mixed in too.
Choose "Same size as each image" to make every page exactly the size of its screenshot, or A4 / US Letter with the image scaled to fit and centred. Transparent areas print as white.
Screenshots on paper: page size and sharpness
A screenshot has no physical size, only pixels. Fitted to the width of an A4 page with a 10 mm margin, common screenshot widths print at about:
| Screenshot width | Printed resolution on A4 | Where it comes from |
|---|---|---|
| 1080 px | about 144 dpi | A full-width phone screenshot |
| 1440 px | about 193 dpi | A high-resolution phone screenshot |
| 1920 px | about 257 dpi | A Full HD monitor |
| 2560 px | about 342 dpi | A 1440p or Retina laptop screen |
For evidence bundles and bug reports, "Same size as each image" keeps every screenshot at its own proportions, one per page, with no white bands; choose A4 when the result will be printed or merged with other A4 documents.

Frequently asked questions
Are my files uploaded?
No. The file is read and processed by your browser on your device; nothing is sent to a server. The PDF engine is downloaded from this site the first time you use a tool and then runs on your device.
Is quality lost?
No. PNG images are stored in the PDF losslessly, pixel for pixel.
Why is my PDF large?
Lossless PNG screenshots can be several megabytes each. If a form has a size limit, run the PDF through Compress PDF afterwards.
Can I mix PNG and JPG?
Yes. JPGs are embedded unchanged; WebP, HEIC, AVIF, GIF and BMP are converted to high-quality JPG.
How many images can I add?
Up to 50 images, 50 MB each, on the free plan.
