Resize Image : what to know
Useful for a profile picture, a banner, a website or a form that requires a specific size. Enter the width or the height: with “Keep proportions”, the other dimension is computed automatically and the image isn't distorted. If you enter both, the image fits inside that box. The original format (JPG, PNG or WebP) is kept.
Frequently asked questions
How do I avoid distorting the image?
Leave “Keep proportions” checked and enter only the width or the height: the other dimension adjusts.
Can I make an image larger?
Yes, but enlarging doesn't add detail: beyond 1.5 to 2 times the original size, the image gets blurry.
What size for a profile picture?
A square of 400 × 400 to 800 × 800 pixels works for most social networks and messaging apps.
Are my files uploaded to a server?
No. The conversion is done by your browser, on your computer or phone: your files are never sent over the Internet or kept by Tooleon. You can even go offline once the page has loaded.
Is it really free?
Yes: free, no sign-up, no watermark and no limit on conversions. The site is funded by ads.
