Image Resizer
100% PrivateImage ToolsResize an image by exact pixels, by percentage, or to a ready-made social media size.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
- 1Choose your image; its current dimensions and file size are shown.
- 2Pick how to resize: exact pixels (with an optional aspect-ratio lock), a percentage scale, or a social preset.
- 3Choose the output format: PNG, JPEG or WebP.
- 4Check the target size, click Resize image, preview the result and download it.
A 4000 x 3000 px photo resized by percentage at 50% comes out at exactly 2000 x 1500 px, one quarter of the pixels, which usually means a file several times smaller. With the aspect lock on, typing a width of 1200 for the same photo sets the height to 900 automatically, so nothing is stretched.
- Resizing stretches or shrinks to the exact target and never crops; if the target has a different shape than the photo, the picture will look stretched. Crop first when shape matters.
- Enlarging beyond the original size is allowed, but it cannot add detail that was never captured.
- Animated GIFs are resized using their first frame only.
Resize scales the whole picture to new dimensions. Crop cuts away edges and keeps the middle at full resolution. The Image Cropper is the right tool when you want to remove part of the scene.
About this tool
The Image Resizer changes an image's pixel dimensions by exact pixels, by percentage, or to a ready-made social size such as an Instagram post or a YouTube thumbnail. It is the tool you need when an upload form demands a specific size or a photo is simply far bigger than the screen it will be shown on.
