Frequently asked questions
Is this image compressor free?
Yes. The tool is designed to run directly in a compatible browser without requiring an account.
Are images uploaded to a server?
The image processing in this tool is performed locally in your browser. The JavaScript does not send the selected image files to a processing server.
What image formats are supported?
JPG, JPEG, PNG and WEBP are the primary formats. GIF, BMP and SVG may work as input when your browser can decode them safely.
Can I compress multiple images?
Yes. You can select multiple images and process them together.
Can I convert JPG to WEBP?
Yes. Choose WEBP as the output format and process your JPG image.
Can I resize images?
Yes. You can use percentage scaling or provide custom width and height values.
Does compression reduce image quality?
For JPG and WEBP, lower quality values can reduce file size while also reducing visual quality. PNG uses a different encoding process.
Does it work on mobile?
Yes. The interface is responsive and designed for modern mobile browsers.
Why can PNG compression behave differently?
PNG is lossless, so canvas PNG encoding does not use the same quality-based compression model as JPEG and WEBP.
Is there a maximum image size?
The practical limit depends on available browser memory, device resources and canvas limitations. Very large images may fail on low-memory devices.
