Is the image compressor free to use?

Yes. It’s free and runs in your browser - no signup, no install.

How do I reduce an image to a specific KB size?

Enter your target in the Target Size (KB) field and compress. The tool lowers quality step by step until the output hits your limit. If it can’t reach it, also enable Resize to lower the pixel size.

Which formats can I compress?

JPG, PNG, WebP, and AVIF inputs are supported. You can keep the original format or convert to any of these during compression.

Will compression hurt image quality?

Lossy formats like JPEG lose some detail by design. Use the quality slider or presets to find the right balance. PNG output is lossless, so it preserves detail but saves less size.

Can I compress many images at once?

Yes. You can upload up to 100 images in one batch, compress them together, and download the results as a single ZIP file.

Does the tool upload my images to a server?

Compression runs in your browser. Files are processed locally and not stored on our servers.
