Overview
Resize an image for a form, webpage, or other space by setting Width (px) and Height (px). The configured result is JPEG, so check the saved file’s dimensions, proportions, and background before using it. Guest access is available for eligible on-device tasks; online processing requires sign-in and an internet connection.
Give your image a smaller space to fit, then check the saved size, proportions and background before you upload it elsewhere.
When to use
- Use Resize Image when a form, webpage, or other destination needs different pixel dimensions. Enter the requested width and height, then check the saved file’s actual dimensions rather than relying on its filename.
- Use it when several images need the same requested dimensions. One set of dimensions is applied to the batch, so check each saved image. If the dimensions are already suitable but the file is still too large, use Compress Images Online to compare file size and appearance.
How to use
Open Resize Image and use its linked workspace. Check the processing mode before continuing: eligible on-device tasks may use guest access; online processing requires sign-in and an internet connection.
Add .jpg, .jpeg, .png, .webp, or .gif images. The tool accepts up to 50 images, each up to 50 MB, and applies one set of dimensions to the batch. Under Options, enter Width (px) and Height (px). The defaults are 800 and 600, and Maintain Aspect Ratio is checked by default. Fill in both fields; changing Width does not automatically update Height.
Choose dimensions that suit the destination. A proportional result may have one dimension below the requested box or leave padding around the image. Check the saved result if the fit matters.
Click Resize. Choose Download for one result or Download All for a batch, if those options are shown. Open the saved JPEG and check its pixel dimensions, orientation, file type, and background. The configured output is JPEG, so do not rely on this workflow to preserve transparency, the original file format, or GIF animation. Keep the original: enlarging a small picture cannot recover missing detail, so look closely at lettering and fine lines in the saved copy.

Examples & use cases
A site editor preparing a wide photo for a page.
Fit a wide photo into a page slot
The page slot allows up to 800 × 600 pixels, but the source photo is wide. A proportional result may be smaller than the full box in one dimension or have padding.
.jpg to JPEG
- Width (px):
- 800
- Height (px):
- 600
- Maintain Aspect Ratio:
- Yes
- Set Width (px) to 800 and Height (px) to 600, using the listed defaults. Leave Maintain Aspect Ratio checked while you see how the wide image fits.
- Open the saved JPEG and check its actual dimensions, proportions, and orientation against the page slot.
Expected outcome
A resized JPEG to check against the page’s 800 × 600 space. Confirm the saved dimensions and fit before uploading it.
A designer preparing an icon for an upload form.
Check a transparent icon for a form
The form requests a 500 × 500 image, and the source PNG has a transparent background. The configured output is JPEG, so the saved background may be solid rather than transparent.
.png to JPEG
- Width (px):
- 500
- Height (px):
- 500
- Maintain Aspect Ratio:
- Yes
- Enter 500 in both Width (px) and Height (px). Keep Maintain Aspect Ratio checked while resizing.
- Open the saved JPEG and check its actual dimensions and background. If the background does not suit the form, keep the PNG and do not use this JPEG there.
Expected outcome
A JPEG made with a 500 × 500 request. Check its pixel dimensions and background against the form’s requirements before submitting it.
A researcher placing a small screenshot in a document.
Enlarge a small screenshot for a document
The screenshot needs a larger working size, but enlarging it cannot restore detail missing from the original. Small text and fine lines need a close check.
.jpg to JPEG
- Width (px):
- 1200
- Height (px):
- 900
- Maintain Aspect Ratio:
- Yes
- Set Width (px) to 1200 and Height (px) to 900. Keep Maintain Aspect Ratio checked while resizing.
- Open the saved JPEG and zoom in on small text and fine lines. Compare them with the original before placing the image in the document.
Expected outcome
A resized JPEG for the document. Check its actual pixel dimensions and whether the screenshot’s text and lines are usable at the intended size.
More ways to use it
- A shop owner preparing product thumbnails.: Several product images need the same requested dimensions for a catalog. One set of dimensions applies to the batch, so check how each saved image fits the target. JPEG results resized using the same requested dimensions. Check each saved image’s pixel dimensions, orientation, and background before adding it to the catalog. Width (px): 500, Height (px): 500, Maintain Aspect Ratio: Yes.
- An applicant preparing an image for a form.: The form specifies pixel dimensions, and a filename alone cannot confirm that the saved image meets them. A JPEG resized with the requested pixel values. Check the saved file’s actual dimensions before submitting it; if the form requires both dimensions exactly, confirm that the result meets both. Width (px): 800, Height (px): 600, Maintain Aspect Ratio: Yes.
Troubleshooting
The saved image is not the width you expected.
Try this: Set Width (px) to 800, then inspect the saved JPEG’s actual pixel dimensions.
What to expect: The requested width is set to 800 pixels. The saved file’s dimensions show what the resize produced.
The saved image does not fill both dimensions of the requested box.
Try this: Check Width (px) and Height (px), then inspect the saved dimensions and proportions. A proportional result may leave one dimension below the requested box.
What to expect: The saved dimensions show how the image fits the requested box; the requested values alone do not confirm the saved size.

Frequently asked questions
Can I stretch an image to an exact width and height?
Width (px), Height (px), and Maintain Aspect Ratio are available controls. The available information does not confirm how turning off Maintain Aspect Ratio works across processing modes, so do not depend on it to stretch an image. Check the saved JPEG’s dimensions and proportions before using it for an exact-size requirement.
Is resizing an image the same as cropping it?
No. Resizing changes pixel dimensions; cropping removes part of the picture. Resize Image lists width and height controls, not a crop control. If you need a different shape without stretching the subject, crop to the intended proportions first, then resize and inspect the saved result.
Will resizing reduce the file size?
Not necessarily. Pixel dimensions and file size in bytes are different measurements. Check the saved file size; if its dimensions are right but the file is still too large, use Compress Images Online to choose a format and quality, then compare the saved size and appearance.
Can I resize several images at once?
Yes. The tool accepts up to 50 images, each up to 50 MB, and applies one set of dimensions to the batch. Use Download All if it is offered, then check the saved files individually.
Which image formats can I resize, and what format is the result?
The configured inputs are .jpg, .jpeg, .png, .webp, and .gif. The configured output is JPEG, so check the saved file type instead of assuming the original format is preserved.
Does the resized image keep transparency or GIF animation?
The configured output is JPEG. Do not rely on this workflow to preserve transparency, the original file format, or GIF animation. Check the saved background and file type, and keep your original if those matter.
How do I resize an image without losing quality?
No listed setting guarantees unchanged quality or fine detail. Enter dimensions suited to the destination, avoid enlarging a small image when you need its original detail, and inspect lettering and fine lines in the saved JPEG before using it.
Can I resize by percentage instead of pixels?
The listed controls use pixel dimensions: Width (px) and Height (px). Enter the dimensions you need in those fields, then check the saved file’s actual pixel size.
Can I resize an image to a particular DPI, inches, or centimeters for printing?
The listed controls set Width (px) and Height (px); no DPI, inch, or centimeter control is listed. For a print requirement given in pixels, check the saved pixel dimensions. The available information does not establish print-size or DPI behavior.
Are my images uploaded to a server?
Online processing uploads files. Completed results may remain available for later download. See Privacy Policy for current file-handling and retention details. Check the processing mode before starting.
How do I make a square avatar from a non-square photo?
Set Width (px) and Height (px) to the square dimensions you need, then inspect the saved image. If you need to change the photo’s shape without stretching the subject, crop it to a square first; resizing does not remove part of the image.
Can I resize an image to exact pixel dimensions online?
You can enter requested pixel values in Width (px) and Height (px). Check the saved JPEG’s actual dimensions before submitting it: entering a requested size does not confirm that both resulting dimensions match an exact requirement.
