✂️ Image Compressor – Exact Target Size

How do I compress an image to exactly 100KB?

Upload your image, enter "100" in the target size field, select "KB", and click "Apply Target". The tool will automatically find the best quality to hit 100KB. Then click "Compress to Target" to download.

Can I compress a PNG to a specific file size like 500KB?

Yes! PNG compression works by adjusting quality or converting to JPG (if ultra mode is enabled). Enter your target (e.g., 500 KB), apply, and the tool will find the optimal settings.

How much can I reduce an image file size?

You can typically reduce by 50-90% depending on the image content. For example, a 1MB photo can often be compressed to 100-200KB with acceptable quality. The tool will show you the result before downloading.

What's the difference between KB and MB targets?

KB (kilobytes) are for smaller files – ideal for web use, email attachments, or thumbnails. MB (megabytes) are for larger files – suitable for high‑resolution images or printing. Use the dropdown to choose your unit.

Will the image quality suffer?

The tool balances quality and file size. It tries to keep quality as high as possible while hitting your target. If your target is very small, quality will be reduced – you'll see the final quality percentage in the preview.

What does "Ultra mode" do?

Ultra mode allows the tool to go below 10% quality if needed and may convert PNG images to JPG for greater compression. This helps hit very small targets, but quality may be lower. You can disable it for gentler compression.

Is this tool really free and private?

Absolutely. All processing happens in your browser – no files are uploaded to any server. Your images never leave your device. No registration, no hidden costs.
