Compress Image
Reduce image file size for faster page loads, email attachments, and storage savings. Move the quality slider and compare estimated file size before you download. Compression runs in your browser — your photos never leave your device.
Frequently Asked Questions
How does image compression work here?
You adjust a quality slider for JPG or WebP, or convert PNG to JPEG for smaller files. The tool estimates the output size so you can balance quality and file weight.
Will compression ruin image quality?
Higher quality keeps more detail but a larger file. Lower quality shrinks the file more. Use the preview and size estimate to find a level that works for your use case.
Why is my PNG converted to JPEG?
PNG is lossless and often large for photos. Exporting as JPEG typically reduces file size significantly for web and email use.
Are compressed images uploaded?
No. Compression is performed locally in your browser.
Which formats can I compress?
JPG, PNG, and WebP are supported. GIF and SVG files are exported as PNG when using this tool.
