How to resize an image
- Drag your pictures into the box above, or click to browse. JPG, PNG and WebP are all accepted, and you can resize a whole batch in one go.
- Choose Exact size and type the width you need — the height follows automatically so nothing gets stretched. Or switch to Percentage to scale everything to, say, 50%.
- Optionally pick a different output format and adjust the quality slider.
- Click Download next to a result, or take the whole batch with Download all.
Exact pixels or a percentage?
Use exact pixels when something else decides the number for you: a profile photo that must be 400×400, a forum that rejects anything wider than 1600px, a print shop asking for a specific size. Type the one measurement that matters and let the other follow — that is what "keep proportions" is for.
Use a percentage when you have a pile of photos at different sizes and you just want them all smaller. Scaling a 4000px photo and a 1200px screenshot to the same fixed width would leave one of them blown up and soft; halving both keeps each one sensible.
Why smaller images are worth the trouble
A photo straight off a modern phone is often 4000 pixels wide and several megabytes. Displayed in a document, an email or a web page it gets squeezed down to a fraction of that — but the full file still has to be stored and sent. Resizing before you upload is the single biggest thing you can do to make pages load faster, emails actually send, and forms stop rejecting your file.
Resizing changes the pixel dimensions. If you want to keep the same dimensions but make the file lighter, use the image compressor instead — and for changing between JPG, PNG and WebP there is the image converter. Need to cut off part of the picture rather than shrink all of it? That is the crop tool.
Frequently asked questions
How do I resize an image to an exact size in pixels?
Drop your image in, type the width you want, and the height fills itself in automatically to keep the proportions. If you need an exact width and height regardless of shape, untick "Keep proportions" first.
Can I resize several images at once?
Yes. Drop as many images as you like and they are all resized with the same settings. Percentage mode is usually the better choice for a mixed batch, because it scales each image relative to its own size.
Will resizing make my image blurry?
Making an image smaller keeps it sharp. Making it much larger cannot invent detail that was never captured, so enlarging always looks softer — that is why the "Don't enlarge" option is on by default.
Are my images uploaded anywhere?
No. The resizer runs entirely inside your browser using the canvas API. Your images never leave your device, and closing the tab removes every trace of them.
