How to reduce image size in KB
- Choose one or more photos.
- Lower the quality (60–80% looks almost identical to the original) and, if needed, set a maximum width.
- Download the compressed images.
Need a photo under 50 KB, 100 KB or 200 KB?
Government and exam application forms often require photos and signatures below a size limit. Set the maximum width to around 600–800 px and lower the quality until the new size is below the limit.
JPG vs WebP vs PNG
- JPG – best for photos and accepted everywhere.
- WebP – usually 25–35% smaller than JPG at the same quality; ideal for websites.
- PNG – lossless, best for screenshots, logos and images with transparency (quality slider has no effect).
