Resize any JPG, PNG, WEBP, GIF or BMP image by exact pixels or by percentage — instantly, in your browser. Nothing is uploaded to a server.
🔒 Everything happens on your device — your image is never uploaded anywhere.
This free image resizer is a browser-based tool that changes the pixel dimensions of a photo or graphic without installing any software or uploading your file to a server. You can resize to an exact width and height in pixels, or scale the whole image up or down by a percentage, then export the result as PNG, JPEG or WEBP at the quality level you choose.
It's built for quick, everyday tasks — shrinking a photo before emailing it, preparing an image for a specific social media size, or reducing file size for a website — without the friction of desktop editing software.
Looking for the Arabic name art tool instead?
Open the Calligraphy Generator →It changes the pixel dimensions of an image you choose, either to an exact width and height or to a percentage of the original size, then lets you download the result as PNG, JPEG or WEBP.
No. The resizing happens entirely in your browser using the HTML canvas element. Your image is never uploaded, stored, or seen by us.
You can upload JPG, PNG, WEBP, GIF or BMP files. You can export the resized result as PNG (lossless, supports transparency), JPEG (smaller file size) or WEBP (modern format with strong compression). Note that animated GIFs are exported as a single static frame.
Shrinking an image generally preserves good visual quality. Enlarging an image beyond its original pixel dimensions can make it look soft or blurry, since no tool can add detail that wasn't in the original file — this tool warns you when a change will enlarge the image.
Yes. Switch to the Percentage tab and use the slider to scale the image anywhere from 1% to 300% of its original size, with the resulting pixel dimensions shown live.
There's no hard limit, but very large files (over roughly 20 MB) or extremely large target dimensions may be slow or use a lot of memory, since everything is processed on your own device rather than a server.
Yes, completely free, with no account, signup or watermark.
Need a smaller file after resizing?
Open Image Compressor →This image resizer helps you change an image to an exact pixel size or percentage while keeping control over its proportions, output format and quality. It is useful when a profile, post, thumbnail, banner or website section needs a specific width and height instead of the dimensions supplied by your camera or phone.
The editor also includes ready social-media sizes and a positioning preview. After choosing a preset, you can drag the uploaded image with your mouse or finger and use zoom to decide which part of the picture should remain visible inside the selected frame.
Resizing changes the pixel dimensions of an image. For example, an image that is 2400 × 1600 pixels can be reduced to a smaller output for a web page, thumbnail or social post. Smaller dimensions can also reduce the amount of image data that a browser needs to display, although final file size also depends on the image format, quality setting and the picture itself.
Resize changes the dimensions of the image. Cropping changes which part of the image is visible. When a selected social-media frame has a different aspect ratio from the original photo, the positioning editor lets you move and zoom the picture so the important subject stays inside the frame.
Start from a ready post, portrait, story, thumbnail or cover size and position the photo inside that frame.
Create images with dimensions that better match a page section instead of uploading an unnecessarily large original.
Prepare a consistent landscape or square image size for cards, previews, galleries and other visual listings.
Use exact width and height values when a platform or layout requires a particular aspect ratio.
Width and height describe the number of pixels in the output. If you only need a smaller version of the same composition, keep the original aspect ratio locked. If you need a different shape—such as turning a landscape photo into a portrait social post—use a target preset and reposition the image rather than stretching it.
Quality affects supported lossy output formats differently from dimensions. Reducing pixel dimensions and lowering quality are separate operations. For logos, graphics and text-heavy artwork, inspect the result carefully so fine edges remain clear. For photographs, a moderate quality setting can often produce a smaller output while retaining a useful visual result.
This version of the resizer performs its resize operation in your browser. The Device option is the working local input in this tool. Google Drive and Dropbox should only be treated as available sources when those services are actually connected; the interface does not claim an unconfigured cloud connection is active.
It can. Reducing pixel dimensions usually reduces the amount of image data, but the final file size also depends on the output format, quality setting and image content.
The target frame may use a different aspect ratio from the original image. Use the drag-position and zoom controls to choose which part of the photo remains visible.
Usually no. Stretching can distort faces, logos and objects. Keeping the aspect ratio or using the positioning/crop workflow generally produces a more natural result.
Yes. The custom width and height controls are useful when you already know the exact pixel dimensions required by your website, document or other destination.
Yes. The layout is responsive, and the positioning area supports touch interaction so an uploaded image can be moved inside the selected frame.
