• No Software Required: Works in browser without Photoshop or desktop tools

Choosing the Right Format: PNG vs JPG

When to Use PNG (Portable Network Graphics)

PNG is the best choice when quality and precision are more important than file size. Choose PNG for:

• Logos and Icons: Keeps lines sharp and colors solid.
• Transparent Backgrounds: The only common web format that supports transparency (invisible backgrounds).
• Text and Screenshots: Preserves text legibility perfectly.
• Digital Art: Maintains the exact quality of your original creation.

When to Use JPG (Joint Photographic Experts Group)

JPG (or JPEG) is the standard for photographs. It's designed to compress photo-realistic images efficiently. Choose JPG for:

• Photographs: Drastically reduces file size for photos with millions of colors.
• Web Images: Smaller files mean faster loading times for your website visitors.
• Email Attachments: Keep your files small enough to send easily.
• Social Media: The preferred format for uploading to Instagram, Facebook, and Twitter.

Understanding "Lossless" vs "Lossy"

The key difference is how they handle data. PNG is lossless, meaning it keeps every single pixel exactly as it was. This is great for quality but results in larger files. JPG is lossy, meaning it intelligently discards some invisible data to make the file much smaller. For photos, the quality difference is usually unnoticeable to the human eye, but the file size savings are huge.

Handling Transparency

One major limitation of JPG is that it cannot have a transparent background—it must be a solid color (usually white). If you convert a specialized logo with a transparent background from PNG to JPG, the transparent parts will turn white (or black, depending on settings). If you need to keep the transparency, you must stick with PNG or use the modern WebP format.
