Compress an image to an exact size

Frequently asked questions

Will compressing reduce image quality?

There's a small trade-off, but the compressor targets visually lossless results by default. You can lower the quality slider further for smaller files, or raise it if you need higher fidelity.

Can I compress an image to a specific size, like 50KB or 100KB?

Yes. Switch to "Target size" mode, enter your desired size in KB, and the tool automatically finds the quality level that gets closest to it.

What image formats are supported?

JPG, PNG, and WebP are all supported for both input and output.

Are my images uploaded to a server?

No. Compression runs entirely in your browser using JavaScript. Your images never leave your device.

Can I compress multiple images at once?

Yes. Select or drag in as many images as you like and they'll be compressed as a batch, each downloadable individually.
