How does the image compressor work?

Our image compressor uses a binary search algorithm to find the optimal compression settings that achieve your exact target file size. It automatically adjusts quality parameters while preserving image dimensions and format.

What image formats are supported?

We support JPEG, PNG, and WebP formats. You can upload images in any of these formats and compress them to your desired file size.

What file sizes can I compress images to?

You can compress images to exact file sizes including 20KB, 50KB, 100KB, 500KB, 1MB, or any custom size you specify. The tool will find the best quality settings to achieve your target.

Is the image compressor free to use?

Yes, our image compressor is completely free to use. No registration, subscription, or payment required. You can compress unlimited images without any restrictions.

Will my images be stored or shared?

No, your images are processed entirely in your browser and are never uploaded to our servers. All compression happens locally, ensuring complete privacy and security of your files.

Can I compress multiple images at once?

Yes, you can upload and compress multiple images simultaneously. The tool supports batch processing, allowing you to compress several images to the same target file size efficiently.

What's the maximum image size I can upload?

The maximum file size depends on your browser's memory capacity, but typically you can upload images up to 50MB. For very large images, we recommend compressing them in smaller batches.

Does compression affect image quality?

Compression will reduce image quality to achieve smaller file sizes, but our algorithm optimizes the compression to maintain the best possible quality for your target file size.

Can I use compressed images commercially?

Yes, you retain full rights to your compressed images. You can use them for any purpose including commercial projects, websites, social media, or print materials.
