Resize PNG and JPG images online by pixels or proportions to quickly fit your web and document needs.
When an image doesn't meet upload requirements or display dimensions, manual cropping or stretching often leads to distortion or blurriness. This tool offers two resizing methods: specifying exact width and height in pixels, or scaling up and down proportionally. Resizing essentially resamples the image pixels, outputting a dimension-adjusted, downloadable PNG or JPG image.
Q: How do I avoid distortion when resizing an image?
A: Be sure to enable the "Lock Aspect Ratio" option in pixel resize mode. The tool will automatically calculate the other dimension based on the original proportions.
Q: What image formats and maximum file sizes are supported?
A: We currently support PNG and JPG formats with a maximum file size of 5MB per image, which is ideal for standard web image resizing.
Please ensure you enter valid pixel values (positive integers) or scale factors (0.1-2.0). Disabling the aspect ratio lock may cause image stretching. Please download your processed images promptly, as the download links may expire.
For web image optimization, we recommend calculating your target pixel dimensions based on the display container size before using the pixel resize mode. For example, scaling a 1200×800 banner image by a 0.5 factor quickly generates a crisp 600×400 thumbnail. Note that excessive upscaling (e.g., beyond 2x) may result in pixelation or blurriness.
