PNG to JPG FAQ
What happens to transparent areas?
JPG cannot store transparency, so transparent pixels are filled with the background colour you select. White is the default.
How much smaller will the file be?
For photographic images, a JPG at 85% quality is commonly 70–90% smaller than the PNG. For flat graphics with few colours the saving is smaller and the PNG may even be the smaller file.
Which quality setting should I use?
Use 80–90% for images you want to look clean, and 60–75% when size matters more. Below 50%, blocky artefacts become visible, especially around text.
Is PNG to JPG conversion reversible?
No. JPG compression discards detail permanently. Keep the original PNG if you might need the lossless version or the transparency later.
Are my images uploaded anywhere?
No. They are processed entirely in your browser.
When JPG is the better choice than PNG
PNG compresses losslessly, which is perfect for logos, diagrams and screenshots but inefficient for photographs, where neighbouring pixels are all slightly different. A camera photo saved as PNG can easily be ten megabytes; the same picture as a JPG is often under one, with no visible difference at normal viewing size.
JPG does have limits. It has no alpha channel, so transparency must be replaced with a solid colour, and its compression produces faint ringing around hard edges such as text. For photos, product shots and anything continuous in tone, JPG is the practical format. For interface graphics, text and images that need transparency, keep the PNG or use WebP.
