Choosing the right image format can dramatically reduce file size and improve quality. Here is a simple breakdown of JPG, PNG, and WebP so you always pick the best one.
JPG (or JPEG)
JPG is best for photographs. It uses "lossy" compression, which means it removes some detail to make files much smaller. For most photos, the quality loss is barely visible while the file size drops significantly.
Use JPG for: photos, and complex images with many colors and gradients.
PNG
PNG is best for graphics, logos, and any image that needs a transparent background. PNG is "lossless", so it keeps every single detail — but the files are usually larger than JPG.
Use PNG for: logos, screenshots, images with sharp text, and transparency.
WebP
WebP is a modern format created by Google that often beats both JPG and PNG. It can be lossy or lossless, supports transparency, and usually produces the smallest files at the same quality level.
Use WebP for: websites and apps, where you want the smallest size with great quality.
Quick rule of thumb
- Photo for a form → JPG
- Logo or transparent image → PNG
- Website image → WebP
Convert freely between JPG, PNG, and WebP — and compress to an exact size.
