Frequently asked questions
- Is the image resizer free?
- Yes — completely free, with no signup, no watermark and no daily limit. Upload an image, set your dimensions and the resized file downloads instantly.
- How do I resize an image without losing quality?
- Upload your image (up to 25 MB), enter the width and height in pixels, choose JPG, PNG or WebP, and press Resize image. The image is scaled with high-quality resampling and is never enlarged beyond its original size, so it stays sharp.
- Will resizing stretch or distort my image?
- No. The image is scaled to fit within the dimensions you enter while keeping its original aspect ratio, so nothing is squashed or stretched.
- What image formats can I upload?
- Almost anything — JPG, PNG, WebP, HEIC, AVIF, GIF, TIFF and more. You choose whether the resized file downloads as JPG, PNG or WebP.
- Can I enlarge a small image?
- No — the resizer scales down only. Upscaling a small image just adds blur, so images are never enlarged beyond their original dimensions.
- Are my images stored anywhere?
- No. Your image is resized in memory and never written to disk, stored or shared. Once the download finishes, it's gone from our servers.
