Benefits

1. Faster website load times from smaller image payloads and better Core Web Vitals
2. Meet email attachment and form upload size limits without paid software
3. Save storage across devices and cloud drives with batch compression
4. No privacy risk since images never leave your browser
5. No software installation, watermark, or account sign-up required
6. Combine with Image Resizer and WebP Converter for a complete web prep workflow

How to Use Image Compressor

1. Drag your image(s) into the upload area, or click to browse and select files from your device
2. Adjust the compression quality slider — lower values save more space; higher values preserve detail
3. Watch each file compress with a live progress bar and resulting size displayed
4. Review the before/after size and percentage reduction for every image
5. Download files individually, or click Download All to save the entire batch
6. If savings are insufficient or quality looks soft, raise the slider and compress again before downloading

Use Cases

Examples

• A 2.4 MB product photo at 75% quality may compress to ~400 KB — enough for most e-commerce listing requirements.
• A batch of ten blog screenshots compressed at 80% can cut total payload from 15 MB to under 4 MB for faster publishing.
• PNG logos with flat colors may see modest savings; photographic JPGs typically see 40–70% reductions at 70–85% quality.

Tips for Best Results

• For web photos, start at 70–85% quality — most viewers cannot tell the difference from the original at normal viewing sizes.
• Compress after resizing: smaller dimensions plus compression yields the best file size for blog and social use.
• Keep your original files untouched and compress copies so you can revert if quality is insufficient.
• PNG screenshots with text compress less aggressively than JPG photos — consider WebP conversion for additional savings.

Limitations

• PNG is lossless, so compression gains are smaller than JPG or WebP unless you also reduce dimensions elsewhere.
• Very large images or large batches may process slowly on older devices since everything runs on your CPU.
• Compression cannot restore detail already lost in a heavily compressed source file.
• There is no hard file-size cap, but extremely high-resolution camera RAW exports converted to JPG may take longer.
