Image File Formats, Types – When to Use Them
If you’ve ever saved a picture and wondered why some images end in .jpg, .png, or .gif, you’re not alone. These endings are called image file extensions, and they’re simply different image file types. Each one has its own strengths, weaknesses, and best uses.
Think of image file formats like different types of backpacks. One might be great for school, another for hiking, another for travel. Images work the same way, different photo formats are built for different jobs.
Here’s a simple, friendly breakdown so you know exactly when to use each one.
Why So Many Image File Formats?
Different platforms want different things.
- Websites want fast loading.
- Phones want small storage.
- Printers want high quality.
That’s why we have so many picture formats. None of them is “the best.” They just shine in different situations.
JPG / JPEG (Joint Photographic Experts Group)
If image formats had a “most popular” award, JPG would win. It’s everywhere, your phone gallery, social media posts, email attachments, and most websites.
JPG uses compression to reduce the file size. Imagine squeezing clothes into a suitcase. You lose a bit of neatness, but it still works fine.
Good for:
• Photos of people or places
• Social media uploads
• Emailing pictures without huge file sizes
Not ideal for:
• Logos
• Images that need super sharp edges
• Anything that requires transparency

PNG (Portable Network Graphics)
PNG is like the neat, organized backpack where nothing gets squished. It keeps images sharp because it doesn’t throw away detail. It also supports transparent backgrounds, which is why designers love it.
Good for:
• Logos
• Icons
• Transparent backgrounds
• Screenshots
Not ideal for:
• Large photo collections (files get big fast)
If you ever need to vectorize a PNG image, you can use Vectorizer AI.
GIF (Graphics Interchange Format)
GIFs are those short looping images you see in messages or memes. They only support 256 colors, so they’re not great for real photos. But they’re perfect for tiny animations.
Good for:
• Memes
• Reaction images
• Small animated clips
Not ideal for:
• High-quality photography
TIFF (Tagged Image File Format)
TIFF is the format photographers and print shops trust. It keeps every detail, almost like a digital “master copy.” But that also means the files are huge.
Good for:
• Professional editing
• Printing
• Saving important, high-quality images
Not ideal for:
• Websites or everyday use
SVG (Scalable Vector Graphics)
SVG files are made of shapes instead of pixels. That means you can zoom in forever, and they stay crisp.
Think of them like vector drawings instead of photos.
Good for:
• Logos
• Icons
• Simple illustrations
• Web graphics
Not meant for photos at all.
WebP
WebP is newer and designed for the web. It keeps quality high but shrinks file size better than JPG or PNG. Most modern browsers support it.
Good for:
• Websites
• Reducing loading times
• Keeping images lightweight
Some older tools still don’t support WebP format Images, but they are updating their platforms now.
HEIC / HEIF (High Efficiency Image Coding)
If you have an iPhone (or some newer Android phones), your pictures may save as HEIC. It keeps quality high but takes up surprisingly little space.
Good for:
• Storing lots of phone photos
RAW
RAW files come straight from professional cameras. They’re like baking ingredients before the cake is finished. You can adjust everything later, brightness, color, shadows, because nothing is compressed.
Good for:
• Photographers
• Detailed editing
Not meant for quick sharing.
Which one should I use?
The best use case of every image file format is as follows:
• JPG/JPEG → everyday photos
• PNG → logos, text, transparency
• GIF → animations
• TIFF → high-end printing
• SVG → icons and graphics
• WebP → fast-loading web images
• HEIC → phone storage
• RAW → pro photography
