JPG, PNG, or WebP: Which Image Format Should You Use?
The useful question is not which image format is best. It is what the image needs to do. A photo sent by email has different requirements from a transparent logo or a screenshot with small text.
EverythingDeck’s Image Converter exports JPG, PNG, and WebP in your browser. The current tool creates a new file and leaves the original unchanged.
A quick way to choose
| Image or task | Try first | Check before saving |
|---|---|---|
| Camera photo for email | JPG | Fine detail at the chosen quality |
| Logo with transparency | PNG | File size at the required dimensions |
| Screenshot with small text | PNG | Text edges and gradients |
| Photo used on a website | WebP or JPG | Browser requirements and visual quality |
| Graphic with transparency | PNG or WebP | Whether the destination accepts the format |
These are starting points. Export a sample and inspect it at the size where people will use it.
JPG for photographs and broad compatibility
JPG uses lossy compression. Lower quality settings remove more image data, which usually reduces file size but can soften detail and create block-like marks around sharp edges.
It works well for photographs because photos contain gradual changes in color and brightness. It is less suitable for logos, interface graphics, or screenshots with small text. Those hard edges can make compression marks easier to see.
JPG does not support transparency. When EverythingDeck converts a transparent image to JPG, transparent areas receive a white background. Check that result before using it on a page with another background color.
PNG for sharp edges and transparency
PNG uses lossless compression, so its quality control behaves differently from JPG or WebP. EverythingDeck disables the quality slider for PNG exports.
PNG is a useful choice for screenshots, diagrams, logos, and graphics with sharp boundaries. It also preserves transparent areas. A PNG photograph can be much larger than a JPG or WebP version, so compare the output size when the image contains many colors and fine details.
WebP when size and transparency both matter
WebP can store photographs with adjustable quality and can also preserve transparency. That makes it useful for website images and other cases where a smaller download matters.
The destination still decides whether WebP is appropriate. Check that the app, publishing system, or recipient accepts it. EverythingDeck also reports an error if the current browser cannot create the requested WebP export.
Conversion does not restore detail
Changing a JPG to PNG does not recover information removed by earlier JPG compression. It changes how the current pixels are stored. Repeated lossy exports can add more visible artifacts, so make new versions from the original file when possible.
Format is only one part of file size. Pixel dimensions and quality also matter. Use the Image Resizer when the original has more pixels than the final use requires, then use the Image Compressor to compare JPG or WebP quality settings.
Open the Image Converter, export one sample, and check transparency, sharp edges, color, and file size before converting the rest.
