How to convert an image
Converting an image can be easier or more complicated, depending on the formats you’re converting between and the tool you use.
1. Identify the source and target file formats
Before converting, determine which format your current image uses (e.g., JPEG, PNG, or WEBP) and what format you need. Different tasks require different formats. Here’s a brief overview about the different image file types.
| Format | Characteristics | Good for |
|---|---|---|
| JPEG | Uses lossy compression, which results in smaller image files that load faster on the web. | Photographs, complex or large images on the web |
| PNG | Supports diverse colors, lossless compression, and transparency. | Logos or graphics with transparent backgrounds |
| WEBP | Web images with good compression, resulting in high-quality images with low files sizes | Photographs and graphics on the web |
| GIF | Supports animation and transparency but is limited to 256 colors | Simple animations or graphics |
| TIFF | Support lossless compression, which results in high-quality images and large file sizes | Professional printing |
| SVG | Vector format; can be resized without loss of resolution | Logos, icons, and other graphics that need to be scaled up and down a lot |
| RAW | Contains the most data from a camera’s sensor, which allows for the best editing possibilities; not suitable for web or printing until converted | Professional photography and editing |
2. Choose a tool that allows for conversion
Next, decide how to convert your image. A few options are:
- Online image converters
- Professional image editing software
- Desktop converter applications
The easiest of these is an online image converter, as you do not need to download and install any programs.
3. Adjust settings and download
Once you select your tool and target format, open (or upload) the image. Apply any needed settings such as compression, quality level, or metadata removal. After processing, download the converted file to your device.
