How to Resize a Photo

Sometimes a photo is too large for an online form or does not fit the dimensions required by a website. You can use this photo resizer to change its width and height without installing extra software.

1. Select the photo you want to resize.
2. Enter the required width and height in pixels.
3. Keep aspect ratio enabled if you want to avoid stretching the photo.
4. Select the output format and image quality.
5. Choose a target file size if you need a smaller image.
6. Click Resize Photo and download the result.

Resize Photo in KB

If a website asks for a photo under 50KB or 100KB, choose the corresponding target size above. The tool will try to reduce the file size while keeping the selected dimensions. If the result is still too large, reduce the dimensions or try WebP format.

The final file size depends on the image's colours, details, dimensions and format. For this reason, an exact file size cannot be guaranteed for every photo.

Image Dimensions and Quality

Image dimensions are measured in pixels. A larger width and height generally preserve more detail but can create a bigger file. Smaller dimensions are useful for thumbnails, profile pictures and forms that require a compact image.

JPG is commonly used for photographs, WebP can offer a smaller file size, and PNG is useful for graphics that need transparency. Choose the format required by the website where you plan to upload the image.

Frequently Asked Questions

Can I resize a photo online for free?

Yes. Select your image, adjust its dimensions and download the resized result using this free browser-based tool.

How do I make a photo 50KB or 100KB?

Choose 50KB or 100KB in the file-size menu and resize the photo. If it remains above the target, try smaller dimensions. The final size can vary from one image to another.

Will resizing affect photo quality?

Reducing dimensions removes image detail, and lossy compression may reduce quality further. Use larger dimensions and higher quality when clarity matters.

Does this tool upload my photo?

The tool processes your selected photo in your browser and does not send it to a PixelKit Tools server. The image is held temporarily by your browser while it is processed.

Can I use it on my mobile phone?

Yes. Open this page in a modern mobile browser, select a photo, set the required dimensions and download the result.
