Good for: screenshot documentation, scanned diagrams for review, printable ui mockups.

Frequently asked questions
Does PNG transparency remain transparent in the PDF?
No. This converter flattens transparent pixels onto white before placing the PNG on a PDF page.
Will small screenshots become sharper?
No. Conversion does not add pixels or recover blurred text; use a higher-resolution original where possible.
Can I turn multiple PNGs into one PDF?
Guests can upload files up to 25 MB each. A free account raises the limit to 50 MB per file, and Premium allows 500 MB per file with larger batches.
How do fit and fill differ?
Fit retains the full PNG within the page. Fill covers the available area and can crop the edges; stretch distorts proportions.
Are my screenshots private?
Uploads are encrypted in transit and deleted automatically after a short time.
Can I use PNG to PDF on an iPhone?
Yes. Select PNG files in a supported mobile browser and download the PDF.
