What’s the Difference Between JPG, PNG, PDF, EPS, and SVG Files?
The best image file type to use depends on what the image is for. Use JPG for photos online, PNG for logos or graphics that need transparency, SVG for scalable logos and icons on websites, and EPS or PDF for professional printing.
Each file format is designed for a specific purpose, and choosing the right one ensures images look sharp, load quickly, and print correctly. Using the wrong file type can result in blurry images, large file sizes, or printing problems. Understanding the differences between JPG, PNG, SVG, EPS, and other formats helps businesses maintain a polished, professional appearance across websites, marketing materials, and digital platforms.

Raster vs. Vector: The Most Important Difference
All image file types fall into two main categories: raster or vector.
Raster images are made of pixels (tiny squares of color). When enlarged too much, they become blurry or pixelated because those pixels stretch.
Common raster formats include JPG, PNG, GIF, TIFF, and RAW.
Vector images are made from mathematical paths and shapes instead of pixels. Because they are not tied to a fixed resolution, they can scale infinitely without losing quality.
Common vector formats include SVG, EPS, AI, and sometimes PDF.
Quick rule:
Use raster files for photos and detailed imagery
Use vector files for logos, icons, and graphics that need to scale
Common Raster File Types Explained
JPG (JPEG) is one of the most widely used image formats.
Best for: Photos, websites, email attachments, social media
Pros: Small file sizes, widely supported
Cons: Loses quality each time it is edited and saved, does not support transparency, can pixelate when enlarged.
JPG files compress images to keep file sizes manageable, making them ideal for online use. However, repeated editing and resizing can reduce image quality.
PNG files maintain image quality and support transparent backgrounds.
Best for: Logos, graphics, web images with transparency
Pros: High quality, supports transparency, no quality loss when saved
Cons: Larger file sizes than JPG
PNG is commonly used for logos or graphics that need to appear clean on websites without a white background box.
GIF files are known for animation.
Best for: Simple animations, memes, short looping graphics
Pros: Supports animation, small file size for simple graphics
Cons: Limited color range, not ideal for high-quality images or professional print
While GIFs are popular online, they are not typically used for professional branding or print materials.
TIFF files are high-quality, detail-rich images often used in professional environments.
Best for: Professional photography, printing, archiving
Pros: Extremely high quality, preserves detail
Cons: Very large file sizes, not suitable for web use
Because TIFF files retain all image data, they are commonly used by photographers and print professionals.
RAW files come directly from digital cameras and contain unprocessed image data.
Best for: Professional photo editing
Pros: Maximum detail and editing flexibility
Cons: Extremely large files, requires editing software
RAW files are ideal for editing but are not meant for sharing or web use without conversion.
Common Vector and Design File Types Explained
SVG (Scalable Vector Graphics) is widely used online for logos and icons.
Best for: Websites, logos, icons, digital graphics
Pros: Scales infinitely without losing quality, small file size for graphics
Cons: Not ideal for complex photos
SVG files keep logos and icons sharp on all screen sizes, from mobile devices to large monitors.
EPS is a standard file format in the professional print industry.
Best for: Professional printing, logo files for vendors
Pros: Maintains quality and color consistency across platforms
Cons: Requires specialized software to edit
Printers and promotional product vendors often request EPS files for logos and graphics.
AI (Adobe Illustrator) files are editable vector design files created in Adobe Illustrator.
Best for: Original design files and editing
Pros: Fully editable, retains layers and paths
Cons: Requires Adobe Illustrator or compatible software
AI files are typically considered the master design file for logos and graphics.
PSD (Photoshop Document) files are layered image files created in Adobe Photoshop.
Best for: Photo editing, graphic design work in progress
Pros: Editable layers and effects
Cons: Large file size, not ideal for sharing final images
Designers use PSD files as working files before exporting final formats.
PDF files can contain both raster and vector elements.
Best for: Sharing files, print-ready documents
Pros: Preserves formatting across devices, widely supported
Cons: Not always ideal for editing without original source files
Many printers request PDFs because they maintain layout and quality across systems.
WEBP is a newer format designed for modern web performance.
Best for: Websites needing fast load times
Pros: High quality with smaller file sizes than JPG or PNG
Cons: Not universally supported in older systems or software
WEBP helps improve website speed without sacrificing image quality.
How to Choose the Right File Type
For photos:
- Use JPG for websites and sharing
- Use TIFF for professional printing
- Use RAW for editing
For logos and graphics:
- Use PNG or SVG for websites
- Use EPS, PDF, or AI for printing
For design work or editing:
- Use AI or PSD as editable master files
For animations:
Use GIF for simple loops and web animation
Why Choosing the Right Image File Type Matters
There is no single “best” image format. The right choice depends on how the image will be used. Using the correct file type ensures images look sharp, load quickly, and print properly. Using the wrong format can result in blurry visuals, formatting problems, or poor print quality.
Understanding the differences between JPG, PNG, SVG, EPS, and other formats helps maintain a polished, professional appearance across websites, marketing materials, and printed assets.
