JPG vs PNG vs WebP: Which Image Format Should You Use?
Compare JPG, PNG and WebP for photos, transparency, screenshots, compatibility and website performance.
The quick comparison
| Format | Best for | Transparency | Compression |
|---|---|---|---|
| JPG | Photos and universal sharing | No | Lossy |
| PNG | Logos, screenshots, sharp graphics | Yes | Lossless |
| WebP | Modern web photos and graphics | Yes | Lossy or lossless |
Choose JPG for compatibility
JPG is dependable for photographs sent through email, uploaded to older systems or opened across many applications. It creates compact photo files, but repeated editing and saving can accumulate artifacts. It cannot preserve transparent pixels.
Choose PNG for sharp graphics
PNG preserves pixels losslessly and handles transparency, so it works well for logos, diagrams, interface screenshots and flat-colour artwork. It is inefficient for most camera photos, where files can become much larger.
Choose WebP for web delivery
WebP can encode photographs efficiently and preserve transparency. It is a strong website default when the publishing workflow accepts it. Keep an original master suited to editing and treat WebP as a delivery format.
Compare fairly
Export from the same source at identical dimensions, then compare both appearance and bytes. A smaller file is not a win if text is blurred or product detail is damaged.
Frequently asked questions
Is WebP always smaller?
No. Results depend on content and settings; simple transparent artwork may remain competitive as PNG.
Can JPG have transparency?
No. Transparent areas must be flattened onto a background colour.
