What this tool does
For supported image formats, the tool outputs an image at the chosen dimensions. Users can keep aspect ratio, set width, set height, or use exact dimensions.
Use this page when an upload form, website, email, or profile image needs a smaller image size and you want the resize operation to happen locally.
Best uses
Useful for
Reducing large phone photos before uploading them to forms or websites.
Useful for
Creating exact pixel dimensions for profile pictures, thumbnails, blog images, and attachments.
Useful for
Lowering file size when the visible quality does not need to remain original-camera quality.
Useful for
Preparing web images without sending the original to a cloud resizer.
How to use
- Select or drag an image into the page.
- Choose width and height. Keep aspect ratio locked if needed.
- Choose output format and quality.
- Click Resize Image and download the result.
Privacy and local processing
Local workflow
- Select a supported image and review the current dimensions.
- Choose exact width and height or resize by percentage.
- Keep aspect ratio enabled unless you intentionally need a stretched output.
- Download the resized copy and check dimensions before using it.
Before sharing the output
- Confirm the output width and height match the target requirement.
- Open the result at normal size to check sharpness and compression.
- Use a larger source image when small text or detailed graphics must stay readable.
- Remember that resizing may strip or change metadata because the image is re-exported.
Supported files and limitations
Supported: JPG, PNG, WebP. Recommended max size: 50 MB.
- Upscaling cannot create true original detail. It only increases pixel dimensions.
- Exact dimensions may stretch an image if aspect ratio is unlocked.
- Animated images are not supported in this starter and may be flattened or rejected.
Image resizing vs image compression
Resizing changes pixel dimensions. Compression changes how image data is encoded. A smaller image often uses both: fewer pixels and a new compression pass. This tool focuses on a predictable local export with dimensions you can verify.
Common mistakes to avoid
- Do not upscale small images and expect new detail to appear.
- Do not disable aspect ratio unless distortion is acceptable.
- Do not use resize as a privacy guarantee; inspect metadata and visible content separately.
- Do not overwrite your original until you confirm the resized output works.
FAQ
Can I resize without losing aspect ratio?
Yes. Keep the aspect ratio option enabled and enter one dimension.
Can I resize to exact pixels?
Yes. Enter both width and height and turn off aspect ratio lock.
Will resizing remove metadata?
Browser re-export usually drops many metadata fields, but use the EXIF remover and metadata viewer to verify.
Is the image uploaded to your server?
No. The image is processed locally.
Which output formats are supported first?
Start with JPG, PNG, and WebP because they cover common browser workflows.
