Frequently Asked Questions

How do I compress an image to a specific size?

Upload your image, enter your desired size in KB or MB, then click Compress. The tool uses a multi-phase algorithm for 99%+ accuracy.

Can I change the image format while compressing?

Yes. Select JPEG, PNG, WebP, or PDF before compressing. The tool auto-detects your uploaded format and selects it by default.

Does PDF compression work with target size?

Yes. When you choose PDF output and set a target size, the tool uses quality and dimension optimization to hit your target precisely.

What if my target size is too small?

The tool will automatically scale down image dimensions to reach very small targets while maintaining the best possible quality.

Does PNG / GIF / BMP compression work?

Yes. These lossless formats can't be quality-compressed, so the tool intelligently scales down dimensions to hit your target size.

Are my images uploaded to a server?

No. Everything runs in your browser. Your images never leave your device.

Is there a file size limit?

You can upload images up to 20 MB. There is no limit on the number of compressions.
