How to use Change Image Dimensions
1. Select your input
Choose a JPG, PNG or WebP image from your device using the file button or supported drop area. The standard file picker accepts browser-readable images up to 25 MB; decoding support depends on the file and browser.
2. Understand the settings
Use the width and height fields and proportional-size control. This focused workflow complements the general resize tool’s percentage mode.
3. Process and review
Enter the required pixels, decide whether proportion or exact bounds matters, process and verify both output dimensions.
4. Save your result
Use the result’s Download control after processing. Keep your original separately and inspect the exported copy at its intended display size; the preview alone is not the file you will share.
Supported formats
Input: browser-readable images, normally JPG, PNG and WebP, up to 25 MB. Output controls include the shown Keep, JPG, PNG or WebP choices. Keep preserves a supported source encoding choice, not byte-for-byte original data; animation is not preserved.
When to use this tool
Use this route when you already know the required pixel width and height. Check whether the original ratio matches the destination before entering both values.
What to check in the result
Stretching a rectangle into a square changes proportions. Crop or pad to the required shape if distortion is unsuitable.
Continue with Change Image Aspect Ratio when that step fits your workflow.
A practical example
Prepare a photo for a fixed-size layout and inspect whether the subject has become wider or narrower.
Capabilities and limitations
Unmatched width and height ratios can distort the image. Use Change Image Aspect Ratio to crop or pad instead.
Troubleshooting
If an exact width and height distort the subject, enable proportional scaling or use aspect-ratio crop/pad instead. Confirm the downloaded dimensions.
Processing and privacy
Image pixels are processed on your device. Loading the website and processing assets still uses a network connection, and hosting may receive normal request information. Keep original files backed up.
Questions about Change Image Dimensions
What if I need an exact size without stretching?
Use cropping or padding to reach the required shape, then export the target dimensions.
Does changing pixels change print DPI?
This tool focuses on pixel dimensions. It is not a print-resolution or colour-profile workflow.
