Our image compressor uses the browser's Canvas API to re-encode images at your chosen quality level. Everything happens locally — your images are never uploaded to any server.
For photos, JPEG at 75% quality typically reduces file size by 60-80% with minimal visible quality loss. For graphics with transparency, PNG is preserved. WebP offers the best compression but may not be supported by all browsers for viewing.
Is this image compressor free?
Yes, completely free. No account, no watermark, no limits.
Are my images uploaded?
No. All compression happens in your browser using the Canvas API. Images never leave your device.
What quality should I use?
For web use, 70-80% is recommended. For archival, use 90%+. Below 50% may show visible artifacts.
Why is my compressed file larger?
Small or already-compressed images may get larger when re-encoded. The tool shows this in red so you can skip those.
