When this tool is useful
Reduce file size while keeping the image dimensions the same. The right choice depends on what is actually wrong with the image. If the dimensions are correct but the file is too heavy, start with compression. If the image is physically larger than the destination needs, resizing can remove unnecessary pixels. If another system requires a different file type, conversion is the appropriate step.
How it works
The core operation runs in your browser using the selected file and the browser's image and Canvas capabilities. The generated result is offered as a local download. This design is intended to avoid a server-side image upload for the core operation.
Common questions
How much can I compress an image?
It depends on the format, dimensions and image detail. Photos often shrink substantially when saved as JPG or WebP at a moderate quality setting, while already-optimized images may shrink very little.
Should I resize or compress first?
If the image dimensions are much larger than you need, resize first. Then compress the smaller image. If the dimensions are already correct, compression alone may be enough.
Does this upload my image?
The core processing in this tool is performed in your browser. The page does not need to upload the selected image to a server to create the result.
