Compress
Local lossy / lossless compression.
A free image compressor that re-encodes images to JPEG or WebP at a quality you choose, showing before/after size and savings. Compression happens locally via the browser canvas — your original is never uploaded.
How to use
- Drag in or choose an image.
- Pick an output format (JPEG or WebP).
- Drag the quality slider and compare the result and size side by side.
- Click Download to save the compressed image.
FAQ
- Are my images uploaded?
- No. Compression is done locally with the browser canvas; images never leave your device — safe for private photos.
- Which output formats are supported?
- You can export JPEG or WebP. WebP is usually smaller at the same quality, but check that your target platform supports it.
- Does the quality setting affect sharpness?
- Yes. Lower quality means a smaller file but more lost detail. Drag the slider while watching the preview to balance size against sharpness.
