Compress Image
Compressing an image means shrinking its file size so it loads faster, uploads quicker, and takes up less storage. Our compressor runs entirely inside your browser: your photos are never sent to a server, so nothing leaves your device.
Pick a target size in kilobytes and the tool automatically finds the best quality setting that still fits. You can also switch the output format — WebP is usually 25–35% smaller than JPG at the same visual quality.
Your images never leave your device. All processing happens locally in your browser.
How to use
- Drop your image into the box above.
- Adjust the target size, width or output format.
- Click download — the file is created on your device.
Frequently asked questions
Does compressing reduce image quality?
Yes, but you control how much. Setting a target file size lets the tool pick the highest quality that still fits. For most web use, 80–85% quality is visually indistinguishable from the original.
Is my image uploaded anywhere?
No. All processing happens locally in your browser using JavaScript and the HTML5 canvas. Your files never leave your device, which also means it works offline after the page loads.
What is the maximum file size I can compress?
There is no hard limit — it depends on your device memory. Photos up to 50–100 MB usually work fine on desktop and modern phones.
