Image Resizer
Resize images online free. Set exact pixels or scale by percentage, alone or in bulk. JPG, PNG and WebP. Private — no upload.
The 10-second test: switch off your Wi-Fi (or turn on airplane mode) and use this tool anyway. It keeps working — because there is no server doing the work.
The technical check: open your browser's developer tools, go to the Network tab, and run the tool. Your file is never sent anywhere.

How to resize an image
Add your images, enter a width or height in pixels (leave one empty to keep proportions), or scale by percentage — then download. Works with JPG, PNG and WebP, one image or a whole batch.
Perfect for profile pictures, marketplace listings, email attachments and forms with strict dimension requirements.
Resizing versus compressing
Two different jobs that people often confuse. Resizing changes the pixel dimensions — a 4000-pixel-wide photo becomes 1000 pixels wide. Compressing keeps the dimensions and reduces the quality to shrink the file. If your problem is "this image is too big to upload", resizing usually helps more, because file size scales with the area: halving both dimensions cuts the pixel count to a quarter. For a target in kilobytes, use the image compressor.
Keeping the proportions
Enter only a width or only a height and the other is calculated automatically, so nothing stretches. Enter both and the image is forced to those exact dimensions, which distorts it unless the ratio happens to match. Forcing exact dimensions is right for things like passport photos with a mandated size, and wrong for almost everything else.
Enlarging
Making an image bigger cannot add detail that was never captured. A 200-pixel image scaled to 2000 pixels will be soft, because the extra pixels are interpolated from neighbours. Always start from the largest original you have.

Frequently asked questions
Will resizing distort my image?
No — leave width or height empty and the other side is calculated automatically to keep the original proportions.
Can I make an image bigger?
Yes, you can scale up to 200%. Note that enlarging can't add detail the photo never had, so slight softness is normal.
Does it work with PNG transparency?
Yes — PNGs stay PNGs, and their transparency is preserved when resizing.
Should I resize or compress to make a photo smaller?
Resize if the image has far more pixels than it needs — file size scales with area, so halving the dimensions cuts it to about a quarter. Compress when you need a specific size in kilobytes.
How do I avoid stretching the image?
Enter only a width or only a height and the other is worked out for you.
Can I make a small image bigger without it going blurry?
Not really. Enlarging interpolates pixels that were never captured, so the result is soft. Start from the largest original you have.
