How to Resize and Compress an Image

- Adjust the dimensions. Enter a new width or height in pixels. Keep Maintain Aspect Ratio selected to preserve the image's proportions.
- Choose an output format. Select JPG, PNG, or WebP.
- Set compression quality. Adjust the quality slider for JPG or WebP. PNG uses lossless encoding.
- Process the image. Click Resize & Compress to generate the new image.
- Download the result. Review the preview and file-size comparison, then download your image.
JPG, PNG, and WebP: Which Format Is Best?
- JPG: Useful for photographs and everyday images. Often provides smaller files with adjustable quality.
- PNG: Useful for graphics, screenshots, and images that need transparent backgrounds. PNG output uses lossless encoding.
- WebP: A modern image format that can offer smaller file sizes while maintaining good visual quality. WebP export availability depends on browser support.
How to Reduce Image File Size
Image file size depends on dimensions, format, image detail, and compression quality. Reducing an image's width and height can significantly decrease its file size.
For photographs, JPG and WebP are often effective choices. For graphics requiring transparency or lossless output, PNG may be more appropriate.
Helpful Tip: For website images, try WebP or JPG at approximately 80–85% quality, then inspect the downloaded image. Text-heavy graphics may need higher quality to remain sharp.
Maintain Aspect Ratio When Resizing
Maintaining aspect ratio helps prevent images from appearing stretched or distorted. When this option is enabled, changing the width automatically adjusts the height, and changing the height adjusts the width.
If you turn off Maintain Aspect Ratio, you can enter custom dimensions independently. This may change the image's proportions.
Private, Browser-Based Image Processing
The Image Resizer & Compressor uses browser-based image processing. Uploaded image files are processed locally rather than being sent to a separate image conversion service.
Share Settings links contain only selected dimensions, output format, compression quality, and aspect-ratio preferences. Uploaded images are not included in shared links.
