FAQ

Will resizing reduce quality?

Enlarging an image beyond its original size may reduce sharpness. Reducing size generally maintains good quality.

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.

Is this tool secure?

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

Frequently asked questions

Will resizing reduce image quality?
Scaling down (making an image smaller) preserves quality well. Scaling up (making it larger) may introduce blur, as the tool has to add pixels that weren't there.
What's the maximum size I can resize to?
There's no hard limit, but very large dimensions may be slow on older devices, as 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.
Can I resize multiple images at once?
Upload multiple files and each will be resized to the same target dimensions.
