JPG vs PNG: what changes when you convert
JPG (JPEG (Joint Photographic Experts Group)) was introduced in 1992 by the Joint Photographic Experts Group and is best known for photos, social media, email attachments. PNG (Portable Network Graphics), created by the PNG Development Group as a GIF replacement, is the better choice when you need logos, screenshots, ui graphics, images that need transparency.
Why convert? PNG files are usually larger than JPG, but you gain pixel-perfect lossless quality. PNG opens on every modern browser and os, so the converted file works anywhere you send it.
Upload one file or a whole batch — conversion happens over a secure HTTPS connection and finished files are automatically deleted from our servers within minutes. PNG photos are pixel-perfect but often 5–10× larger than an equivalent JPG.

How do I convert JPG to PNG?
Upload your JPG files on this page. PurePDF opens the conversion workspace with PNG preselected — click Convert and collect the finished files from the download hub.
Will converting JPG to PNG reduce quality?
No. PNG supports lossless compression, so every pixel of your JPG image is preserved exactly.
Why is my PNG file larger than the original JPG?
PNG prioritizes lossless quality over compression, so files are usually larger than JPG. That is normal and expected.

Are my files private?
