What Does the Image Compressor Do?
The Image Compressor shrinks JPG, PNG, and WebP photos to a fraction of their size with barely visible quality loss. Smaller images mean faster websites, quicker uploads, and emails that actually send — without paying for storage or a desktop app.
You can target an exact file size in KB — the tool automatically finds the best quality setting to hit your target — or use the quality slider for manual control. Compare the original and compressed versions side by side before downloading. Everything runs locally in your browser, so your photos are never uploaded anywhere.
How to Use It — Step by Step
- Upload a JPG, PNG, or WebP image.
- Set your target size in KB or adjust the quality slider.
- Compare the original vs compressed preview and file sizes.
- Download the smaller image — free, no watermark.

Frequently Asked Questions
How does the exact KB compression work?
The tool automatically adjusts image quality and dimensions until the file size is at or just below your target KB. It tries the highest quality first, so you get the best looking image at your target size.
Is my image uploaded to a server?
No. Everything happens in your browser — your image never leaves your device. This also means unlimited free use with no queues.
What format is the compressed image?
Images are compressed to JPEG for the smallest size. PNG images with transparency are converted — if you need transparency, use our Background Remover instead.
Will compression reduce image quality?
Some quality loss is unavoidable when reducing file size, but the tool finds the best possible quality for your target size. For small reductions (e.g. 500KB to 200KB) the difference is barely visible.
