Can I reduce an image to 500 KB?

Yes. Choose Custom target size, set 500 KB, and we search for the highest quality encoding that fits when possible.

Why can't every file reach the exact target size?

Some images are already small or use formats that resist further compression. We stop before quality becomes unusable and show the actual result size.

Will compressing ruin my photo?

You control the tradeoff. Start with Balanced or a realistic target, then download only if you like the result.

Which format compresses best?

Photos usually shrink well as JPG or WebP. Graphics with flat colors often stay sharper as PNG, though PNG files can stay larger.

Is the image compressor free?

Yes. Compress images online free with no registration.

Are my photos uploaded?

No. Compression runs in your browser, so images are not sent to our servers.
