Frequently Asked Questions
Does resizing an image affect its quality?
If you shrink an image (downsizing), the quality is generally preserved while the file size drops. However, enlarging an image past its original pixel count (upscaling) may cause it to become blurry or pixelated. Use the quality slider carefully when saving as JPG to balance sharpness and file size.
Is my private data safe on imimg.online?
Absolutely. The imimg.online resizer uses client-side processing. Your image files are read, resized, and downloaded entirely inside your web browser. Nothing is ever uploaded to our servers.
What is Aspect Ratio and why lock it?
Aspect ratio is the proportional relationship between the width and height of an image. Leaving the "Lock Aspect Ratio" box checked ensures that when you change the width, the height adjusts automatically, preventing your image from looking distorted or squeezed.
Can I convert my images using this tool?
Yes! Under the Output Settings, you can choose to save your resized file in a different format. You can easily convert PNG to JPG, or save heavy files as modern, web-optimized WEBP files.
