Image Compressor

Private Image Compressor — Compress Images Without Uploading

Reduce image file size without sending your photos to a server. Unlike TinyPNG, Squoosh, and most online compressors, this tool runs entirely in your browser — your images are never uploaded anywhere. It supports JPG, PNG, and WebP with an adjustable quality slider so you stay in full control of the output size.

How to Compress an Image

1. Click the upload area or drag and drop your image file.
2. Adjust the quality slider — lower values produce smaller files, higher values preserve more detail.
3. Click Compress Image.
4. Review the original size, compressed size, and percentage saved.
5. Download the compressed image.

Tips and Best Practices

• A quality setting of 75-85% typically offers the best balance between file size and visual quality for most photos.
• For web use, aim for images under 200 KB — this significantly improves page load speed.
• PNG images with large areas of solid color often compress very well. Photographs with many colors benefit most from JPEG compression.
• Check the preview after compressing to make sure the quality is acceptable before downloading.
• If the compressed file is still too large, try lowering the quality slider further or resizing the image dimensions first.

Common Use Cases

Website owners compress images to speed up page load times and improve SEO rankings. Social media managers reduce photo sizes to meet platform upload limits. Email users compress images before attaching them to stay within attachment size caps. Bloggers and content creators optimize their images for faster delivery to readers.
