How to resize an image
The resizer gives you three ways to set a new size, each for a different need:
- Pixels— type an exact width and height. Keep "Lock aspect ratio" on and fill just one side to scale the other automatically.
- Percent — scale by a percentage, like 50% to halve every dimension. The proportions are always preserved.
- Preset — pick a ready-made size such as an Instagram post or a Full HD frame and let the tool do the maths.
Drop your images in, choose a mode, and download the results — one by one or as a single ZIP.
Understanding aspect ratio
An image's aspect ratio is the relationship between its width and height. Change one without the other and the picture stretches — faces go wide, circles turn into ovals. To stop that from happening by accident, "Lock aspect ratio" is on by default, so the shape is always kept.
When you do need an exact frame — say a perfect 1080×1080 square from a landscape photo — turn the lock off and choose how the image should fill it:
- Contain fits the whole image inside the frame and pads the leftover space, so nothing is cut off.
- Cover fills the frame edge to edge and crops the overflow, so there are no bars.
Stretching is never an option — your image keeps its proportions whichever you pick.
Common sizes and where they're used
- 1080 × 1080 — the square Instagram feed post, and a safe size for most profile pictures.
- 1080 × 1920 — the full-screen vertical frame for Instagram and TikTok stories.
- 1920 × 1080 — Full HD: presentation slides, YouTube thumbnails and desktop wallpapers.
- 600 × 600 — a 2×2 inch passport-style photo.
- 800 × 600 — a lightweight size for forum posts, email and older displays.
Why resize in your browser?
Resizing here runs entirely on your device, so a folder of forty product photos is reshaped in seconds with no upload, no account and no watermark. Because the files never leave your computer or phone, there's nothing to store and nothing to leak — useful when the images are clients' photos or anything you'd rather keep private.
Next steps
Frequently asked questions
- Will resizing stretch or distort my image?
- No. With "Lock aspect ratio" on, the proportions are always kept, so distortion is impossible. If you turn it off to force an exact width and height, you choose Contain (pad the edges) or Cover (crop the overflow) — the image is never stretched.
- How do I keep the same proportions?
- Leave "Lock aspect ratio" on and enter just one side — the other is calculated for you. Or use the Percent mode, which always scales both sides together.
- Can I make an image larger?
- Yes, you can enlarge as well as shrink. Bear in mind that enlarging can't add detail that isn't in the original, so very large increases will look soft.
- Can I resize many images to the same size at once?
- Yes. Drop in a whole batch and they are all resized to your settings on your device, then you can download them together as a ZIP — handy for product photos or a set of avatars.
- Are my images uploaded anywhere?
- No. Resizing happens entirely in your browser. Your files are never uploaded, so nothing is stored or seen by us.
