The History of Image Formats: From Paintbrush to Pixels
Image formats weren’t always this fancy. Let’s travel back a bit.
1980s: BMP and TIFF dominated desktop publishing.
1992: JPG was released to make image files smaller and web-friendly.
1996: PNG emerged after licensing issues with GIF.
2010s: WEBP, developed by Google, became the web’s favorite due to its balance of quality and size.
Today: SVG and EPS are widely used in scalable web and print designs.
Stat Source: According to a 2023 Harvard Business Review study, over 85% of web images are now compressed formats like JPG or WEBP.
Brief Overview of Each Image Format
JPG/JPEG (Joint Photographic Experts Group)
JPG is one of the most widely used image formats today. Known for its efficient lossy compression, it’s ideal for photographs and web use where smaller file sizes are essential. JPG balances quality with space savings, making it perfect for sharing and storing large numbers of images.
PNG (Portable Network Graphics)
PNG is a lossless image format best known for supporting transparency and crisp quality. It’s widely used for web graphics, icons, and images where precision and clarity are key. It’s especially useful for logos and screenshots that require high fidelity.
GIF (Graphics Interchange Format)
GIF is best recognized for its animation capabilities. It supports only 256 colors, which limits its use for high-quality images but makes it ideal for memes, emotive content, and simple web animations. Its looping feature is especially popular on social media.
TIFF (Tagged Image File Format)
TIFF is a professional-grade image format designed for archiving, printing, and photography. It offers both lossless and uncompressed options, preserving the highest possible image quality. It’s frequently used in publishing, medicine, and high-end photography workflows.
BMP (Bitmap)
BMP is a raw and uncompressed format that preserves exact pixel data. It’s an older format that sees less use today due to its large file size, but it’s still found in some Windows-based applications where image fidelity is paramount.
SVG (Scalable Vector Graphics)
SVG is a vector-based format, meaning it uses mathematical paths instead of pixels. This allows images to be resized infinitely without quality loss. SVG is ideal for icons, illustrations, infographics, and responsive web design.
EPS (Encapsulated PostScript)
EPS is a legacy vector format used mainly in professional and print-based design. It supports high-resolution illustrations and is often used for logos and other artwork intended for printing. It can be opened and edited in programs like Adobe Illustrator.
WEBP (Web Picture)
WEBP is a modern format developed by Google to reduce image file sizes while maintaining quality. It supports both lossy and lossless compression, as well as transparency and animation, making it a versatile option for web optimization.

Common Image File Extensions: What They Mean
.jpgor.jpeg= Compressed image file.png= High-quality image with transparency.gif= Animated or flat-color image.tiffor.tif= High-res image, print-focused.bmp= Raw, old-school bitmap.webp= Modern web-optimized image.svg= Scalable vector graphics.eps= Vector format for print
Stat Alert: The National Institutes of Health (NIH.gov) states that high-resolution TIFF files are still the standard for medical imaging due to their lossless nature.
My Personal Experience with Image Format Fails
Back in college, I designed a club flyer in Photoshop and exported it as a JPG. Looked great on screen—but the print came out pixelated. The print shop told me, “Next time, save it as TIFF.”
That was a facepalm moment. From then on, I made it a habit to ask: What’s the end use? Print or digital?
That simple question has saved me from countless do-overs. I recommend you do the same.
