FAQ

Will resizing reduce quality?

Scaling down (making an image smaller) preserves quality well. Scaling up (making it larger) may introduce blur, since the tool has to add pixels that weren't there.

What does "lock aspect ratio" mean?

It means the width-to-height proportion stays the same. If you change one dimension, the other adjusts automatically to avoid stretching the image.

What's the maximum size I can resize to?

There's no hard limit, but very large dimensions may be slow on older devices, since processing happens locally in your browser.

Does resizing change the file format?

No — the output format matches your input. A JPG in produces a JPG out.

Is this tool secure?

Yes. Your images are processed locally in your browser and never uploaded to any server.
