Free Image Resizer
This free image resizer changes a picture to the exact width and height you type, or to a percentage of its current size, and lets you keep the original proportions so nothing looks stretched. Upload a JPG, PNG, WebP, GIF or BMP up to 8 MB, choose the output format and download the result. The file is processed in memory and never stored.

About this tool
Pictures from a phone or camera are usually far larger than any web page, email or form needs. An upload field that asks for 800 pixels wide, a product listing that wants a square image, or a page that crawls because it loads a 6000 pixel photo are all fixed the same way: resize the picture to the size it will actually be shown at. This tool does that without installing anything.
Choose pixels to type an exact width, height or both, or choose percent to scale everything by one number, such as 50 for half size. With keep proportions switched on, typing only a width calculates the height for you, and typing both fits the picture inside that box without distortion. Switch it off when you need the exact size and accept that the picture will stretch. Scaling down gives clean results; scaling up cannot add detail that was never there, so enlarged photos look soft.
The result can be saved as PNG, JPG or WebP, or kept in the original format. Transparent areas become white when you save as JPG. Resizing re-encodes the picture, which removes camera metadata such as GPS location and applies the photo rotation. Keep your original file, because every lossy save adds a little damage. The limit is 8 MB per upload and 8000 pixels on the longest side of the result.
Frequently asked questions
How do I resize an image without making it look stretched?
Keep the "keep proportions" box ticked and type either a width or a height. The tool works out the other side from the original shape. If you type both, the picture is fitted inside that box so it is never squashed. Only untick the box when you truly need an exact width and height.
What size should an image be for a website?
Make it about as wide as the space it fills, doubled at most for sharp screens. A blog column of 800 pixels rarely needs more than 1600 pixels of width. Anything much larger just slows the page. Resize first, then run the picture through an image compressor for the smallest file.
Can I make a small image bigger without losing quality?
No. Enlarging only stretches the pixels that already exist, so the picture turns soft or blocky. A small enlargement of about 120 to 150 percent is usually fine. For larger jumps, go back to the original file or retake the picture at a higher resolution.
Which formats can I upload and save?
You can upload JPG, PNG, WebP, GIF and BMP files up to 8 MB. Results can be saved as PNG, JPG or WebP. An animated GIF is read as a single still frame. Choose PNG when you need transparency and JPG or WebP when you need the smallest file for a photograph.
Is my image uploaded or stored anywhere?
The file is sent to our server only so it can be resized, held in memory while that happens, and discarded when the page finishes loading. It is not saved to disk or shared. The resized picture shown in the result exists only on that page, so download it before you leave.
