PNG, JPG, or WebP
Different image formats are useful in different situations. Choose based on transparency, file size, and platform support.
| Format | Best for | Reminder |
|---|---|---|
| PNG | Images that need transparency or sharp edges | Files can be larger. |
| JPG | Photos and general uploads | Transparent areas become white. |
| WebP | Web images with smaller file sizes | Check platform support before uploading. |
Format Selection Examples
If you are not sure which output format to choose, start from the destination. Websites, forms, design tools, and social platforms may accept different formats.
| Scenario | Suggested format | Reason |
|---|---|---|
| Photo upload form | JPG | High compatibility and reasonable file size. |
| Logo or graphic with transparency | PNG | Preserves transparent areas. |
| Website image where smaller size matters | WebP | Often smaller than JPG or PNG when supported. |
| Image for later editing | PNG | Avoids another round of lossy compression. |
Quality and Transparency Notes
Converting an image can change file size, transparency, and visual quality. Pick the format based on what the image contains and where it will be used.
| Concern | Best choice | Why |
|---|---|---|
| Keep transparency | PNG or WebP | JPG cannot store transparent pixels. |
| Small photo file | JPG or WebP | Both can compress photo-like images well. |
| Sharp UI screenshot | PNG | Keeps edges and text cleaner. |
| Modern website asset | WebP | Often smaller, but confirm platform support. |
FAQ
Is my image uploaded?
No. The conversion runs in your browser.
When should I use JPG?
JPG is useful for photos or images that do not need transparency.
When should I use WebP?
WebP is often useful for smaller web images when the target platform supports it.
What happens to transparency when converting to JPG?
JPG does not support transparency, so transparent areas are flattened into a solid background.
