Resize images to exactly the dimensions you need: type a new width or height in pixels and the other side follows automatically, scale by a percentage, or pick a ready-made preset for Instagram, Facebook, X, YouTube and passport-style photos. It works with JPG, PNG and WebP and can resize a whole folder in one go.
When a preset has a different shape from your photo, choose whether to crop it to fill the frame or fit the whole picture inside with a background colour. Resizing uses gradual step-down scaling for smooth, sharp results. It all happens on your device, so there is no waiting for uploads and your photos stay yours.

Common image sizes for social media
Instagram feed posts look best at 1080 × 1080 px (square) or 1080 × 1350 px (portrait). Stories, Reels covers and TikTok use 1080 × 1920 px. A YouTube thumbnail is 1280 × 720 px, an X (Twitter) header 1500 × 500 px, and a Facebook page cover displays at 851 × 315 px on desktop. Platforms change their layouts from time to time, so check their help pages for the latest numbers.
Uploading an image at the recommended size means the platform does less recompression of its own, which usually gives you a sharper result than uploading a huge original.
Crop to fill or fit inside?
Crop to fill scales the photo until it covers the whole target frame and trims the edges that stick out, so there are no empty bars; it is the right choice for profile pictures and thumbnails. Fit inside shrinks the photo until all of it is visible and fills the remaining space with a colour of your choice, which is useful for product photos or artwork where nothing may be cut off.
Frequently asked questions
How do I resize an image without stretching it?
Keep Lock aspect ratio switched on and type only the width or the height. The other side is calculated to keep the original proportions.
Does resizing reduce file size?
Yes, making an image smaller in pixels almost always makes the file smaller. To hit a specific size in KB, use Compress Image to KB.
Can I make an image bigger?
You can enlarge images, but no tool can add real detail that was not captured, so big enlargements look soft. Resizing down always keeps images sharp.
Can I resize many photos at once?
Yes. Add as many images as you like; the same settings are applied to each and you can download them all as one ZIP.
Are my images uploaded?
No. Resizing is done in your browser and the images never leave your device.
