GRID16

Compress an image

This tool reduces the file size of a JPG, PNG or WebP image without changing its format. Everything runs in your browser, so the file is never uploaded. Lowering the quality slider makes JPG and WebP files smaller; PNG is compressed losslessly, so its pixels do not change.

Runs in your browser

JPG, PNG, or WebP, up to 50 MB

Questions

Does compressing lower the quality?
For JPG and WebP, a lower quality number gives a smaller file with more visible loss of detail. PNG compression is lossless: the pixels stay exactly the same.
Does the file format change?
No. A JPG stays a JPG, a PNG stays a PNG and a WebP stays a WebP.
What is the default quality?
70. You can raise or lower it before running the tool.
What is the size limit?
Each image can be up to 50 MB and up to 50 megapixels, depending on what your browser can handle.
