Can I compress an image to 20KB, 50KB or 100KB?

Yes. Choose a preset or enter any custom KB or MB target.

Will the result be exactly the requested number of bytes?

File encoding works in discrete steps, so AG File Tools aims to stay at or just below the limit rather than promise an exact byte count.

Why can the image dimensions become smaller?

After quality adjustment reaches its practical limit, reducing pixel dimensions is the remaining way to meet a much smaller file-size target.

Are my files uploaded to your server?

No. Your files never leave your device. Processing happens privately in your browser.
