Frequently Asked Questions
Which image formats can I compress?
You can compress JPG, JPEG, PNG, and WEBP files. Simply upload any of these formats and the tool will automatically handle the compression.
Will the image quality be reduced after compression?
You have full control over the quality. By setting the compression quality slider between 80% and 90%, the image will look visually identical to the human eye but the file size will be drastically reduced (often by 50% or more).
Are my images uploaded to a cloud server?
No, absolutely not. All image compression runs locally within your browser using the HTML5 Canvas API and modern JavaScript. Your images never leave your local device, guaranteeing total data privacy.
Is there a limit on how many images I can compress?
There are zero limits. You can compress as many images as you want, completely for free. You do not need to create an account, sign up, or pay any subscription fees.
