Format comparison
JPG vs PNG: Which Should You Use?
Compare JPG and PNG for photos, graphics, transparency, text sharpness, editing and website file size.
The core difference
JPG compresses images by discarding information that is less noticeable in many photographs. PNG stores pixels losslessly and supports alpha transparency. The correct choice depends on image content and destination—not on one format being universally superior.
Choose JPG for photographs
JPG is a strong default for camera photos, social images and email attachments when smaller size and broad compatibility matter. Quality settings let you trade file size against visible artifacts. Repeatedly editing and saving JPG can accumulate damage, so retain a high-quality original.
Choose PNG for sharp graphics and transparency
PNG works well for logos, icons, diagrams, interface screenshots and images containing small text or flat color. It also supports partially transparent pixels. A photographic PNG may be many times larger than a visually similar JPG, so use it only when its properties are needed.
What happens during conversion
JPG to PNG changes the container and prevents another lossy save at that moment, but cannot restore information already removed. PNG to JPG requires replacing transparent areas with a background and introduces lossy compression. Check the background color and text edges before publishing the JPG result.
Website decisions
For the web, also evaluate WebP or AVIF when the publishing stack and target browsers support them. Regardless of format, resize to the required display dimensions, specify width and height in the page layout and test the final asset in context.
Frequently asked questions
JPG vs PNG: Which Should You Use? FAQ
Is PNG higher quality than JPG?
PNG is lossless, while JPG is lossy. That does not make PNG the best choice for every image; photographic PNG files can be unnecessarily large.
Which format supports transparency?
PNG supports alpha transparency. JPG does not, so transparent areas must be replaced with a solid background.
Which is better for photos?
JPG is usually more efficient for ordinary photographs when broad compatibility and smaller files are important.
Which is better for logos and screenshots?
PNG is often better for logos, interface screenshots, diagrams and text-heavy graphics because it preserves hard edges without JPG artifacts.
Does converting JPG to PNG restore lost quality?
No. PNG prevents additional lossy encoding, but it cannot recreate detail discarded during the earlier JPG compression.
