JPG (JPEG) Explained

JPG is the most widely used image format in the world. It's been around since 1992 and is supported by virtually every device and application.

How JPG Works

JPG uses lossy compression, which means it reduces file size by discarding some image data. At high quality settings (80-100%), this loss is invisible to most people. At lower settings, you may notice artifacts, especially around edges and text.

JPG Strengths

• Universal compatibility - Works everywhere, always
• Good compression - Much smaller than uncompressed images
• Adjustable quality - Balance size vs. quality as needed
• Widely understood - Everyone knows how to work with JPG

JPG Limitations

• No transparency - Can't have see-through areas
• Lossy - Each save loses some quality
• Not ideal for text/graphics - Can show artifacts on sharp edges

Best for: Photos, sharing, social media, general use.

PNG Explained

PNG (Portable Network Graphics) was created in the mid-1990s as a patent-free alternative to GIF. It's now the standard for images requiring perfect quality or transparency.

How PNG Works

PNG uses lossless compression, meaning no image data is discarded. The original quality is perfectly preserved, though this results in larger file sizes compared to JPG.

PNG Strengths

• Perfect quality - No compression artifacts, ever
• Transparency support - Full alpha channel for see-through areas
• Great for graphics - Sharp edges, text, screenshots
• Lossless editing - Can edit and save without quality loss

PNG Limitations

• Larger file sizes - Typically 2-10x larger than JPG
• Not ideal for large photos - File size can become impractical
• Slower loading - Bigger files take longer to load on web

Best for: Screenshots, graphics, logos, images with text, when transparency is needed, professional work requiring quality preservation.

WebP Explained

WebP is Google's modern image format, introduced in 2010 and now supported by all major browsers. It offers the best of both worlds: excellent compression with high quality.

How WebP Works

WebP supports both lossy and lossless compression. In lossy mode, it typically produces files 25-35% smaller than equivalent JPG images. In lossless mode, it's smaller than PNG.

WebP Strengths

• Excellent compression - Smallest file sizes at given quality
• High quality - Better than JPG at same file size
• Transparency support - Like PNG, supports alpha channel
• Modern format - Designed for today's web

WebP Limitations

• Browser support - Older browsers don't support it (though 95%+ now do)
• Not universal - Some apps/software can't open WebP
• Email issues - Some email clients can't display WebP

Best for: Website images, web apps, when smallest file size matters, modern web projects.

Format Recommendations by Use Case

Social Media

Use JPG - All platforms accept it, and most will re-compress your image anyway.

Email Attachments

Use JPG - Universal compatibility ensures recipients can open it.

Website/Blog

Use WebP - Fastest loading times. Provide JPG fallback for older browsers.

Professional Printing

Use PNG (or JPG at 100%) - Print services want maximum quality.

Screenshots

Use PNG - Sharp edges and text look best with lossless compression.

Graphics/Logos

Use PNG - Transparency support and crisp edges.

Photo Archives

Use PNG or keep HEIC - Preserve original quality for future use.

Conclusion

Here's the simple summary:

• JPG - The safe choice. Works everywhere, good quality, reasonable file size. Choose this when unsure.
• PNG - The quality choice. Perfect quality, transparency support, but larger files. Choose for graphics or when quality is critical.
• WebP - The modern choice. Best compression and quality, but limited to modern platforms. Choose for web optimization.

For most people converting iPhone photos for sharing, JPG at 80% quality is the right choice.
