How to use Resize Image
1. Select your input
Choose a JPG, PNG or WebP image from your device using the file button or supported drop area. The standard file picker accepts browser-readable images up to 25 MB; decoding support depends on the file and browser.
2. Understand the settings
Pixel width/height, percentage scaling and Maintain aspect ratio are different ways to express the target.
3. Process and review
Choose the resize method, enter the target, keep the aspect ratio when appropriate, process and verify the downloaded dimensions.
4. Save your result
Use the result’s Download control after processing. Keep your original separately and inspect the exported copy at its intended display size; the preview alone is not the file you will share.
Supported formats
Input: browser-readable images, normally JPG, PNG and WebP, up to 25 MB. Output controls include the shown Keep, JPG, PNG or WebP choices. Keep preserves a supported source encoding choice, not byte-for-byte original data; animation is not preserved.
When to use this tool
Change the size of a photo for a website, email or layout. Preserve the aspect ratio when the subject should retain its original proportions.
What to check in the result
Width and height are pixel counts, not a guaranteed file size. If a destination also imposes a KB limit, resize first and then compress the exported copy.
Continue with Compress Image when that step fits your workflow.
A practical example
A 2400×1600 photo becomes 1200×800 when scaled to half its width without distortion.
Capabilities and limitations
Resizing does not recover absent detail. Entering incompatible dimensions with the ratio unlocked can stretch the subject.
Troubleshooting
If the image looks stretched, turn on proportional scaling and change only one dimension. For a different shape, use crop or aspect-ratio controls.
Processing and privacy
Image pixels are processed on your device. Loading the website and processing assets still uses a network connection, and hosting may receive normal request information. Keep original files backed up.
Questions about Resize Image
Does resizing keep the original proportions?
Use the proportional option; changing both dimensions independently can stretch the picture.
Does a smaller pixel size always mean a smaller file?
Not always. Format, quality and image detail also affect the encoded file size.
