FAQ
Resizing questions
What does "maintain aspect ratio" mean?
Aspect ratio is the proportional relationship between width and height. When locked, changing one dimension automatically adjusts the other to keep the image from appearing stretched or squished. This preserves the original image quality and appearance.
Can I make images larger?
Yes, you can increase dimensions. However, enlarging images beyond their original size may reduce quality. For best results, resize to smaller dimensions or sizes closer to the original.
Which format should I use after resizing?
Choose JPG for photos and general use (best compatibility), PNG for images with transparency or graphics, or WebP for modern websites and smaller file sizes. All three formats support high quality at various file sizes.
What's the maximum size I can resize to?
You can resize up to 9999 pixels in any dimension. However, practical limits depend on your browser memory and the original image quality. Most use cases work with dimensions under 4096 pixels.
Will resizing hurt image quality?
Reducing image dimensions improves quality by decreasing file size with minimal visual loss. However, enlarging (upscaling) can reduce quality. Resizing to smaller dimensions typically maintains or improves quality.
Is my image data stored anywhere?
No. All resizing happens directly in your browser. Your image never leaves your device or connects to any server. Complete privacy and security guaranteed.
