JPG vs PNG vs WebP: Which Image Format Should You Use?
Understand the trade-offs between JPG, PNG and WebP for screenshots, photos and web graphics.
When JPEG is the better fit
JPEG remains useful for photos where small file size matters more than perfect sharp edges or transparency.
If your image is mostly photographic and you need broad compatibility, JPEG is still a practical default.
It is also the format people reach for when they care more about keeping an attachment small than preserving every edge in a screenshot or every transparent area in a graphic.
Where PNG and WebP win
PNG is ideal for transparency, screenshots and graphics that need crisp edges.
WebP often delivers smaller files than PNG or JPEG while keeping good visual quality, making it a strong option for modern websites.
In everyday work, PNG tends to be the safe edit format, while WebP is the format you pick when the final destination is the web and page weight matters.
A practical rule of thumb
If it is a photo, start with JPEG. If it needs transparency or sharp UI edges, start with PNG. If the goal is web delivery and you want smaller files, test WebP against the others and compare the actual result instead of guessing.
A quick side-by-side preview is almost always more useful than arguing about formats in the abstract.
