How to compress an image
- Drop your image into the box above.
- Choose output format and drag the quality slider (lower = smaller file).
- Files are compressed automatically — compare the sizes, then download.
Tip: lower quality means a smaller file. PNG is lossless, so the quality slider has no effect on it.
Frequently Asked Questions
Will compression reduce image dimensions?
No — width and height stay the same; only the file size shrinks. To change dimensions, use our Resize Image tool.
Is my image uploaded?
No. Compression runs locally in your browser via canvas.
Which format gives the smallest file?
Usually WebP at quality 70–80. JPEG is the most compatible choice.
