JPG, PNG, and WebP Compression
JPG
Useful for photographs where smaller files are often more important than lossless storage.
PNG
Useful for crisp graphics and images that need transparency, although PNG files can become large.
WebP
Useful when your destination supports it and you want a modern web image format.
Choosing a Quality Setting
The slider runs from 0.40 to 1.00 and starts at 0.82. That value is a good starting point for photos. Lower it for thumbnails, or raise it when detail matters. The setting affects JPG and WebP output. PNG is lossless, so the slider does not change a PNG. To shrink a photo saved as PNG, choose JPG or WebP as the output format.
Compress or Resize First?
Compression reduces file size without changing the pixel dimensions. If the image is far larger than you need, reduce its dimensions first with Resize Image and then compress it. Images above 6,000 pixels on a side are scaled down by the tool.
Reading the Result
After processing, the tool shows the original size and the new size. You can check the saving before you download.
Supported Files and Output
