Frequently Asked Questions

What is aspect ratio?+

It is the relationship between width and height. Keeping it locked means that if you change one number, the other changes automatically so the picture does not look stretched.

Does resizing reduce file size?+

Yes. Fewer pixels means a smaller file. For even smaller files, follow up with the Image Compressor.

Can I make a small image bigger?+

You can, but it will look blurry because new pixels are guessed. Always start from the largest original you have.

Is my data safe?+

Yes. Everything runs inside your own browser. Your text, files and images are never uploaded to any server.

Is this tool really free?+

Yes — completely free, no signup, no watermark and no usage limit.
