Understanding Image Resizing
Resizing an image correctly is key to maintaining its quality. Here are the core concepts:
Pixels & Dimensions
A digital image is made up of thousands of tiny dots called pixels. The dimensions of an image are its width and height in pixels (e.g., 1920 x 1080). When you resize an image, you are changing the number of pixels it contains.
Aspect Ratio
The aspect ratio is the proportional relationship between an image's width and height. For example, a 4x6 photo has the same aspect ratio as an 8x12 photo. Keeping the aspect ratio locked prevents your image from being stretched or distorted when you change its size.
Frequently Asked Questions (FAQs)
Will resizing my image reduce its quality?
Making an image smaller (downsizing) generally maintains quality well. However, making an image significantly larger (upsizing) than its original dimensions can cause it to look blurry or "pixelated" because the software has to guess what the new pixels should look like.
What's the best image format to use: JPEG or PNG?
Use JPEG for photos with many colors and gradients, as it provides excellent compression. Use PNG for images with sharp lines, text, or transparent backgrounds, as it preserves detail perfectly without loss of quality.
Is my uploaded photo secure?
Yes. This tool is 100% private. Your image is never uploaded to a server. All resizing is done directly on your computer within your web browser. When you close this page, your image is gone.
What image type will the output be?
You can choose to download your resized image as a **JPEG (.jpg)**, **PNG (.png)**, or **WEBP (.webp)** file. JPEG is great for photos, PNG is best for graphics with transparency, and WEBP offers excellent quality at a smaller file size.
