Free Image Compressor
Reduce JPG, PNG and WebP file size in your browser while you control how much quality to keep.
Compress photos and graphics online with an adjustable quality slider so you can shrink file size while minimizing visible quality loss. Supports JPG, PNG and WebP. Processing stays on your device — nothing is uploaded for compression. Use a higher quality setting when you need to preserve photo detail for print or portfolios; lower it for web, email and chat attachments.

- Set quality — higher keeps more detail; lower shrinks the file more.
- Click Compress and compare the new size to the original.

Frequently Asked Questions
Is image compression free?
Yes. The Image Compressor is free to use with no signup required.
Do you upload my images to a server?
No. Compression runs entirely in your browser. Your files never leave your device.
Does compression remove all quality loss?
JPG and WebP use lossy compression, so some detail can be discarded. At moderate-to-high quality settings, visible loss is often minimal for web use. Raise the slider if faces, text or fine detail look soft.
How do I preserve photo quality while reducing size?
Start around 70–85% quality, compare the preview size, and only lower further if you still need a smaller file. Resizing oversized dimensions first (Image Resizer) often saves more space than crushing quality alone.
Can this stop photos from looking over-compressed?
This tool cannot restore detail already lost in a heavily compressed file. For best results, compress from a high-quality original and choose a higher quality setting so you control how much compression is applied.
