Frequently Asked Questions
Common questions about image resizing and upscaling
What does this tool do?
This tool increases image resolution by 2x or 4x—e.g. 500×500px becomes 1000×1000 or 2000×2000. Dimensions are increased without AI enhancement; output is the same image at higher pixel dimensions.
What's the maximum scale?
You can resize images to 2x or 4x their original size. For example, 400×400px becomes 800×800 (2x) or 1600×1600 (4x). There are no file size or dimension limits.
Does resizing improve image quality?
This tool only increases resolution (pixel dimensions). It does not add new detail or reduce pixelation—you get the same image at a larger size, which can help meet minimum size requirements for platforms or print.
What file formats are supported?
We support JPG, PNG, GIF, BMP, and WebP. Output is always PNG. There is no maximum file size.
How long does processing take?
Resizing is done in your browser and is typically instant or a few seconds, since it's a simple resolution increase with no AI.
Do you store my images?
No. Resizing runs entirely in your browser. Your images never leave your device and we never store or access them.
