Percentage Resizing Made Practical
Use relative scaling when you know how much bigger or smaller the image should be, but do not want to work out the exact width and height.
Scale From the Original
The new size is calculated from the image you upload. Pick 50% for half size, 200% for double size, or use the slider for a custom result.
Keep the Same Shape
Width and height change together, so the image keeps its natural proportions. This helps avoid stretched photos and distorted graphics.
Useful Preset Percentages
Start quickly with 25%, 50%, 75%, or 200%. These cover common needs like thumbnails, previews, lighter uploads, and larger layout drafts.
Format and Quality Choices
Export as JPG, PNG, or WebP. Use quality control when you want to balance a clean-looking image with a smaller file.
Private Browser Workflow
Your image is processed locally in your browser. You can test different percentages without sending the file to a remote server.
Good for Repeat Tasks
Percentage scaling is handy when you need the same relative size again and again, such as quick drafts, content previews, or asset variants.
Resize by Percentage in 3 Steps
Upload an image, choose a scale, and download the resized result.
Upload Your Image
Choose a JPG, PNG, WebP, GIF, or AVIF file. The tool reads the original width and height so it can calculate the percentage size accurately.
Pick a Percentage
Use a preset such as 50% or 200%, or move the slider to choose a custom percentage between the minimum and maximum allowed values.
Export the New File
Check the output resolution, choose the format and quality, then download the resized image when it looks right.
Create a Percentage-Based Resize
Make a quick proportional copy of your image for drafts, uploads, previews, or layout testing.
