What is Image Format Conversion?
Image format conversion allows you to change an image from one file format to another, such as converting a PNG to JPG or a JPG to WebP. Different formats have different strengths: JPG (JPEG) is best for photographs and complex images with many colors due to its efficient lossy compression. PNG is ideal for images that require transparency or have sharp edges like logos and text. WebP is a modern format developed by Google that offers smaller file sizes than both JPG and PNG while maintaining comparable quality.
How to Use
- Select an image file (JPG, PNG, or WebP) using the file picker above.
- Choose the desired output format from the dropdown: JPEG, PNG, or WebP.
- Adjust the quality slider for JPEG or WebP output (PNG ignores quality settings as it is lossless).
- Click "Convert image" to generate the converted version, then download it.
Frequently Asked Questions
When should I use JPG vs PNG vs WebP?
Use JPG for photographs and images with gradients where small quality loss is acceptable. Use PNG when you need transparency or pixel-perfect quality for logos, icons, and screenshots. Use WebP when you want the smallest possible file size for web use, as it supports both lossy and lossless compression with transparency.
Does converting PNG to JPG remove transparency?
Yes. JPG does not support transparency. When you convert a PNG with a transparent background to JPG, the transparent areas will be filled with a solid color (usually white or black). If you need to keep transparency, use PNG or WebP format.
Is my image uploaded to a server?
No. All format conversion happens entirely in your browser using the HTML5 Canvas API. Your image never leaves your device, ensuring complete privacy and security.
