Free Image Resizer & Compressor Tool
Resize photos, convert PNG, JPEG, or WebP images, and compare file size before downloading. Your image stays in your browser.
How to use this tool
- Choose a PNG, JPEG, or WebP image from your device.
- Optionally set a maximum width or height; the tool keeps the aspect ratio and never enlarges the image.
- Choose an output format and quality, create the new copy, compare sizes, then download it.
How the calculation works
The browser draws a local image to a canvas, scales it down to fit optional maximum dimensions while preserving its aspect ratio, then encodes a new copy in your chosen format and quality. The original file is unchanged.
A quick example
An image that is 2,400 × 1,600 pixels with a maximum width of 1,200 pixels becomes 1,200 × 800 pixels, with its original proportions preserved.
Common questions
Which image formats are supported?
You can open PNG, JPEG, and WebP files, then create a PNG, JPEG, or WebP copy. Browser support may vary for WebP encoding.
Are my photos uploaded?
No. This tool processes the selected file in your browser and does not send it to a SoloKit application server.
Does resizing change the original file?
No. The tool creates a separate download and leaves your source image untouched.
