Frequently Asked Questions
How can I reduce image size in KB?
Upload your image, switch on Target file size, enter the KB limit such as 20, 50 or 100 and click Resize & Compress. The tool lowers the quality step by step until the file fits the limit.
Can I make a 50 KB or 100 KB photo?
Yes. Choose JPG or WebP, switch on Target file size and enter 50 or 100. If the picture is very large, reduce its width and height as well so the target can be reached.
How do I change an image to 300 DPI?
Enter 300 in the DPI box and download the image as JPG or PNG. The DPI value is written into the file. When you use cm, inch or mm, DPI also decides the final pixel size.
Can I resize a photo by cm, inch or mm?
Yes. Select CM, Inch or MM, enter the size and set the DPI. The tool shows the final size in pixels before you download.
Can I resize an image by percentage?
Yes. Open the By Percentage tab and enter a value such as 25, 50 or 75. The proportions of the image stay the same.
Why can't I compress a PNG to a target KB?
PNG is a lossless format, so quality cannot be reduced to hit a size. Choose JPG or WebP for target-size compression.
Are my images uploaded to a server?
No. Resizing, cropping and compression happen inside your own browser. Your photo is not sent to any server.
Can I use this tool on my mobile phone?
Yes. The tool works in the browser of any modern smartphone, tablet or computer and needs no app or software.
Privacy
100% In-Browser Processing
Your image is resized, cropped and compressed on your own device. It is never uploaded to our server or to any third-party service.
No Account, No Watermark
The tool is free, needs no login and does not add a watermark to your image. The crop feature loads a small open-source library (Cropper.js) only when you click Crop.
