JPG — Best for Photos
JPG (also written JPEG) is the most widely supported image format in the world. It uses lossy compression, which means it removes some image data to achieve smaller file sizes. At quality settings of 75–85%, this loss is invisible.
JPG is ideal for photographs, social media images, and anything where you need broad compatibility. It is the default format for camera photos and smartphone photos.
Use JPG when
- ✓Sharing photos on WhatsApp or email
- ✓Uploading to social media
- ✓Maximum compatibility needed
- ✓File size is more important than perfection
Avoid JPG when
- ✗Image has text or sharp lines
- ✗Transparency is required
- ✗You need to edit and re-save repeatedly
PNG — Best for Graphics and Transparency
PNG uses lossless compression, meaning no image data is ever removed. Every pixel is stored exactly as-is. This makes PNG perfect for logos, screenshots, icons, and any image that contains sharp edges or text.
PNG also supports full transparency (alpha channel), making it the go-to format for logos that need a transparent background. JPG cannot do this.
The trade-off is file size. A PNG photo is typically 3–5× larger than the same photo saved as JPG. For photographs, PNG is overkill — use JPG or WebP instead.
WebP — Best for Websites
WebP was developed by Google specifically for web use. It supports both lossy and lossless compression, plus full transparency. The result is files that are 25–35% smaller than JPG at equivalent visual quality.
All modern browsers — Chrome, Firefox, Safari, Edge — support WebP. If you are building a website or web app, WebP is the best choice for performance.
The limitation is that some older software and apps (like WhatsApp and some email clients) do not handle WebP well. For sharing files with others, JPG or PNG is still safer.

Use JPG — widest compatibilityFrequently Asked Questions
Which image format is best for websites?
WebP is best for websites because it produces the smallest file sizes while maintaining good quality. JPG is a reliable fallback for browsers that do not support WebP. Avoid PNG for photos on the web as file sizes are unnecessarily large.
Can I convert a JPG to PNG without quality loss?
Yes. Converting JPG to PNG is lossless in the conversion step — the PNG simply stores the JPG's current pixel data without further degradation. However, any quality lost when the original JPG was saved cannot be recovered.
Does PNG support transparency?
Yes. PNG supports a full alpha channel, meaning each pixel can be fully transparent, fully opaque, or anywhere in between. JPG does not support transparency at all. WebP also supports transparency.
Is WebP supported by all browsers?
WebP is supported by all modern browsers including Chrome, Firefox, Safari (since version 14), and Edge. Internet Explorer does not support WebP, but IE usage is below 1% globally as of 2026.
