Three ways to resize
Type a width or a height and the other side follows automatically, scale by a percentage, or pick a ready-made size for Instagram posts, Stories and Reels, YouTube thumbnails or Full HD screens.
Ready-made sizes fill the whole frame by trimming the edges evenly from the center, so the picture is never squashed or stretched.

Same format, sharp result
The resized image keeps its original format: JPG stays JPG, PNG keeps its transparency, WebP stays WebP. iPhone HEIC photos are saved as JPG so they open everywhere.
Resizing runs on your device with the browser's high-quality scaler, so even a batch of photos is quick and private.
Frequently asked questions
Does resizing make the file smaller?
Yes — fewer pixels means a smaller file. If you need to get under a specific size in KB, use Compress Image instead.
Can I make an image bigger?
You can enter a larger size, but enlarging can't add detail that isn't there, so the result may look soft.
Are my photos uploaded?
No. Every image is resized inside your browser and never leaves your device.
