Frequently asked questions
Which formats are supported?
Upload JPG or PNG images and export in JPG, JPEG, or PNG.
Do my images leave the browser?
No. Everything runs locally using a web worker, so files never leave your device.
How does target size work?
Target size adjusts JPEG quality until the file is close to the size you specify.
Will EXIF rotation be applied?
We read EXIF orientation when possible and fall back to the original orientation if it cannot be detected.
Resize images without leaving your browser
ReduceImages makes it simple to change dimensions for social posts, product shots, or marketing graphics. Set the exact width and height you need or resize by percent to scale images quickly. If you want an image size reducer that also trims file weight, switch on compression controls and export a smaller KB file without losing clarity.
You can work in pixels for digital layouts, inches or centimeters for print, and keep the aspect ratio locked to avoid stretching. The output format choices help you decide between lighter JPG files and crisp PNG exports for graphics or screenshots.

ReduceImages resizes JPG, JPEG, and PNG files directly in your browser. Upload one of those formats to get started.
Can I reduce the KB size as well as the dimensions?
Yes. You can resize by dimensions and also use compression controls to reduce file size in KB.
Does the resizer keep the aspect ratio?
By default the aspect ratio is locked, so your image stays proportional when you change width or height.
Will resizing reduce image quality?
Resizing can slightly change quality depending on your settings, but you can fine-tune the output quality before downloading.
Is there a limit to image size?
Large images can take longer to process, but there is no hard server-side limit because everything runs on your device.
