Image Resizer FAQs
Does resizing change the file format?
No. The resized image keeps the original format — JPG stays JPG, PNG stays PNG. Use the Image Format Converter if you also want a different format.
What does the aspect-ratio lock do?
It keeps the original proportions: when you change the width, the height updates automatically (and the other way around), so the image never looks stretched.
Can I make an image bigger?
Yes, but enlarging cannot add detail that was never there, so the result may look soft. For printing, stay close to the original size.
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser — your images never leave your device.
What size should I use for social media?
Square posts commonly use 1080 × 1080 px and HD video covers 1920 × 1080 px, but every platform differs — check the current recommendation for the one you use.
