Image Compressor
Reduce an image's file size right in your browser, without uploading it anywhere.
Drag and drop an image, or choose one from your device
Processed entirely in your browser — this image is never uploaded to a server.
How it works
Choose an image and drag the quality slider — the preview updates instantly so you can find the smallest file size that still looks good, then download the result.
Frequently asked questions
- Is my image uploaded to a server?
- No. Compression happens entirely in your browser using the canvas API — the file never leaves your device.
- Why does the output download as a .jpg?
- JPEG's adjustable quality setting is what makes size reduction possible. If you need a PNG or WebP output instead, try the resize or format-conversion tools.
