How to Resize an Image — Step by Step
1
Upload your image. Click the "Choose Image" button or drag and drop a JPG, PNG, or WebP file onto the upload area. Your image loads instantly — nothing is sent to any server.
2
Set your target dimensions. Enter the Width and Height values in pixels. The aspect ratio lock (đ) is enabled by default — change one dimension and the other adjusts automatically to prevent distortion. Unlock it to set custom dimensions independently.
3
Choose your output format. Select JPG for photographs and smaller file sizes, PNG for images with transparency, or WebP for modern browsers with best compression.
4
Click "Resize Image". The tool processes your image instantly using your browser's built-in Canvas API. A preview of the resized image appears immediately below.
5
Download your resized image. Click the Download button to save the result to your device. The filename includes the new dimensions so you can keep track of multiple versions.

Frequently Asked Questions
Is this image resizer really free? Are there any limits?
Yes, completely free — no account, no subscription, no watermark, and no hidden limits. You can resize as many images as you want. Rekreay is funded by advertising, so the tool stays free for everyone.
Does my image get uploaded to your servers?
No. Your image is processed entirely inside your browser using the HTML5 Canvas API. Nothing is ever sent to any server. This means your files are 100% private, and the tool works even without a strong internet connection once the page is loaded.
What image formats does this resizer support?
You can upload JPG (JPEG), PNG, and WebP images. You can also choose your output format independently — for example, upload a PNG and download it as a JPG or WebP. Note: if your source image has a transparent background (PNG with alpha), saving as JPG will fill the transparency with white.
Will resizing an image reduce its quality?
Scaling an image down to smaller dimensions is generally lossless for PNG and maintains excellent quality for JPG. Scaling up (enlarging) beyond the original resolution will soften the image as the browser interpolates pixels — this is a fundamental property of bitmap images and applies to all image resizers, not just this tool. For best results, always work from the highest-resolution source you have.
What does the aspect ratio lock do?
When the aspect ratio lock is enabled (the đ button is blue), changing the Width automatically recalculates the Height to maintain the original image's proportions, and vice versa. This prevents your image from looking squashed or stretched. Disable the lock if you intentionally want to set a custom width and height that differs from the original ratio — for example, to fit a specific social media template size.
Is there a maximum file size or image dimension?
There is no fixed file size limit imposed by the tool — it is limited only by your browser's memory. In practice, images up to 20–30 MB process without any issue on most modern devices. The output dimension is capped at 8000 × 8000 px to prevent browser canvas memory errors.
