Reduce JPG file size while maintaining acceptable visual quality. Our JPG compressor lets you control compression level to find the perfect balance between file size and image quality. All processing happens in your browser for complete privacy.
Control quality from 1-100%. See real-time file size estimates. Find the sweet spot between quality and size for your needs.
Reduce JPG file size by 50-90% depending on quality setting and original image. Typical compression at 80% quality saves 40-60%.
All compression happens locally using Canvas API. Your photos never leave your device - zero uploads, complete privacy.
See original and compressed file sizes side-by-side. Know exactly how much space you're saving.
Compress one image at a time with no daily limits. Process as many as you need - completely free.
JPG compression is performed entirely client-side in your browser using JavaScript and Canvas API. Your images are never uploaded to servers. We have zero access to your photos. Verify by checking browser network tab - no upload requests occur. Works offline after initial load.
80% is recommended for most photos - significant size savings with minimal visible quality loss. 70% for aggressive compression. 85-90% if quality is critical. Test to see what works for your image.
JPG uses lossy compression - some quality is lost. At 80%+, differences are usually imperceptible on screen. Below 70%, artifacts may become visible in detailed areas.
Varies by image and quality setting. Typical results: 80% quality = 40-60% size reduction, 70% quality = 60-80% reduction, 60% quality = 70-90% reduction.
Technically yes, but quality degrades with each compression. Artifacts compound. Always compress from original high-quality sources when possible.
Limited only by browser memory. Most devices handle 20-50MB images easily. Very large files (100MB+) may be slow or fail on low-memory devices.
Resize first, then compress. Smaller dimensions = smaller files. Compressing a large image then resizing wastes quality and processing time.
