Compress images locally
Upload an image, choose WEBP quality, and ImageConvert uses the browser canvas to create a smaller WEBP copy. The file stays on the device for this local tool.
Supports JPG, JPEG, PNG, WEBP, AVIF, SVG, BMP and JFIF files. PSD, RAW and specialist image source files are explained before upload is enabled in browser tools.

FAQ
Are my images uploaded to a server?
No. Compression runs locally in the browser with canvas export. The source file stays on your device and is not sent to ImageConvert servers.
What output format does this tool create?
This page exports WEBP only. Lower quality usually creates a smaller file, but compression artifacts are permanent.
Which input formats can I compress?
JPG, JPEG, PNG, WEBP, AVIF, SVG, BMP and JFIF when the browser can decode them. PSD, RAW and specialist image source files are guide-only until safe processing is available.
Can I compress to JPG or PNG here?
No. Use the Image Converter for other output formats, or resize first with the Resize Image tool if you need a PNG copy at a new size.
