What does Resize Image do?
Resize Image is a free online tool that can fit an image within width and height bounds while keeping proportions. The PNG result from Resize Image is a separate copy to inspect before you use it elsewhere. One possible use is photos fitted within a website content area.
Image resizing fits a picture within the width and height you supply while retaining its proportions. It is useful for a bounded display area or a smaller upload, but the result may not be exactly both requested width and height.
ImageMagick's ordinary resize geometry keeps aspect ratio unless explicitly forced, and this form does not force it. Distinguish fitting from cropping: resizing keeps the whole picture while changing the number of pixels used to represent it.
Width and height describe a bounding area for the resized picture. The usual resize path keeps the image's shape rather than stretching it to fill that area.
Check the actual output size after download. A square source need not become a wide banner. Crop first if the destination needs a different shape.
Fit image dimensions to bounds online: steps
Before using Resize Image, decide what the new copy must contain and where it will be used. Choose width and height bounds based on the target layout, and check the source aspect ratio. Review the upload area and all values required by the current Resize Image form.
Choose the source
Check the exact pixel size required by an upload form. For Resize Image, choose one source from your device. Keep a source copy for another attempt.
Review the form values
Width controls a value used by Resize Image. The starting Width value is 1920.
Height controls a value used by Resize Image. The starting Height value is 1080.
Run the file task
Use Process Resize Image after checking the source and form values. Wait for the job to finish. An error means this attempt failed.
Save and check the output
Check actual output width and height, subject proportions and the readability of embedded text. Store the output on your device. Name this copy separately from the original.
Fit dimensions: uses for Resize Image
Resize Image can help with large scans reduced for a preview. It can also be used for picture assets sized for a file template. The PNG result from Resize Image must suit the intended reading or editing step, so keep the source until that check is complete.
- Photos fitted within a website content area.
- Large scans reduced for a preview.
- Picture assets sized for a file template.
- Images prepared for a portal with dimension bounds.
Formats and limits for Resize Image
The Resize Image form accepts the image formats in the table sources. Each Resize Image upload can be up to 300 MB, which equals 300 MiB. The allowed suffixes on the Resize Image page do not prove that a source has valid content inside it.
| Accepted formats | Maximum file size | Output |
|---|---|---|
| JPG, JPEG, PNG, WEBP, GIF, TIF, TIFF | 300 MB per file (300 MiB upload limit) | PNG |
Upsizing cannot recover missing source detail. To create an exact shape such as a square, crop the image in a separate step.
How this tool works
Resize Image uses ImageMagick to handle the source on the server. The Resize Image request uses your chosen input rather than any local editing project left on your device. Check the PNG contents produced by Resize Image before treating them as ready for another app or reader.
For Resize Image, your browser uploads the source to our file-processing server. This is a server task, not local editing.
Files are due for deletion within 1 hour. Cleanup runs during normal service operation. Keep a local download for future use.
