PNG vs JPG: what changes when you convert
PNG (Portable Network Graphics) was introduced in 1996 by the PNG Development Group as a GIF replacement and is best known for logos, screenshots, ui graphics, images that need transparency. JPG (JPEG (Joint Photographic Experts Group)), created by the Joint Photographic Experts Group, is the better choice when you need photos, social media, email attachments.
Why convert? JPG files are typically much smaller than PNG — expect a noticeable reduction in file size. JPG opens on every browser and device ever made, so the converted file works anywhere you send it. note that PNG transparency is not supported in JPG — transparent areas are filled with a white background.
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. Re-saving a JPG repeatedly degrades quality a little each time.

Frequently
Asked
Questions
Quick answers about this PurePDF workflow.
How do I convert PNG to JPG?
Upload your PNG files on this page. PurePDF opens the conversion workspace with JPG preselected — click Convert and collect the finished files from the download hub.
Will converting PNG to JPG reduce quality?
JPG uses lossy compression, so there is a small quality trade-off in exchange for a much smaller file. At the default quality setting the difference is invisible for photos and everyday images.
What happens to transparency when converting to JPG?
JPG does not support transparency. Transparent areas in your PNG file are filled with a solid white background. If you need to keep transparency, convert to PNG or WebP instead.
How much smaller will my file be as JPG?
It depends on the image content, but JPG typically produces significantly smaller files than PNG. Photographic images see the biggest savings.
Is the PNG to JPG converter free?

Are my files private?

Can I batch convert multiple PNG files?
