Frequently Asked Questions About Image Compressor
Upload your image and set the quality slider to 80–90%. This typically reduces file size by 50–70% while keeping the image visually indistinguishable from the original. For photos, JPEG compression at 85% is the industry-standard sweet spot.
Web images should be under 200KB for product photos and blog images, and under 100KB for thumbnails and icons. Smaller files directly improve your Core Web Vitals (LCP) score, which Google uses as a ranking factor.
Lossy compression (used for JPEG) permanently removes some image data to achieve large file reductions. Lossless compression (used for PNG) reduces file size without removing any data. Lossy gives smaller files; lossless preserves every pixel perfectly.
Set the quality to 70–80% for email compression — this keeps the image readable while reducing the file below the typical 5–10MB email limit. For very large photos, reduce dimensions with the Image Resizer first, then compress.
No. All compression happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device and are never uploaded, stored, or processed on any server. Compression is 100% private and browser-based.
The Image Compressor accepts JPG, PNG, and WebP files. Output is saved as JPG for photos (best compression ratio) and PNG for graphics with transparency. The tool shows file size before and after so you can see the exact saving.
