Choose dimensions before quality
Reducing the width and height can cut file size without relying only on compression. Start with the destination requirements and inspect small text and fine edges.

A practical example
Fit a 2400 × 1600 photo within 1200 × 1200
With proportions preserved, a 2400 × 1600 image fitted within 1200 × 1200 becomes 1200 × 800. The image stays in proportion rather than becoming square.
- Enter the maximum width and height and keep the aspect-ratio control enabled.
- Choose the output format, resize and check the resulting pixel dimensions.
Disable proportions only when stretching is intentional. Enlarging a small image cannot create new photographic detail.
Back to the toolAbout the image resizer: instructions and questions
Resize JPG, PNG and WebP images by pixel dimensions. Keep proportions, choose the output format and download.
How to use the image resizer
- Choose images. Add photos or graphics and check their original dimensions.
- Set pixel limits. Enter maximum width and height. Keep aspect ratio for a proportional fit, or turn it off for an exact stretched size.
- Save the resized copies. Choose JPG, PNG or WebP. Compare the preview and download the results.
Make the next step easier
Match the space where the image will be used.
An image often needs fewer pixels for a form, email or website than the original camera file contains.
Use the format that fits
JPG fills transparent areas with white. PNG and WebP can keep transparency. Keep your original when a larger print or another edit may be needed later.
Image Resizer questions
Is this free without an account?
Yes. There is no signup, payment gate or added watermark. The stated limits keep the work manageable on your device. Your result is a normal downloadable file.
Are my files uploaded?
No. These tools read and process files in your browser tab. File contents are not sent to a conversion server or a paid API. Download the result before closing the tab. Normal website hosting and page analytics still apply.
Does this crop my image?
No. With aspect ratio enabled, the entire image fits inside your width and height limits. With aspect ratio disabled, the image is stretched to the entered dimensions.
Can I enlarge a small image?
Only when Allow enlargement is enabled. Enlarging adds pixels by interpolation, not new photographed detail. Check sharpness before using the result.
Can I resize to a specific file size?
This tool targets pixel dimensions, not an exact number of kilobytes. Choose a lower JPEG or WebP quality, or use the image compressor for size comparisons.
