❓ Frequently Asked Questions
Is this Image Resizer free?
Yes, 100% free with no signup, no watermark, and no usage limits.
Are my images uploaded to a server?
No! Everything happens in your browser. Your images never leave your device.
What image formats are supported?
JPG, JPEG, PNG, WEBP, GIF, BMP, SVG, and any other format your browser can display.
What does “Keep aspect ratio” do?
It automatically adjusts the height when you change the width (and vice versa) so the image doesn’t get stretched or squished.
Does resizing reduce file size?
Yes. Making an image smaller (fewer pixels) usually reduces file size. Making it larger increases file size but not quality.
What format is the output?
The resized image is saved as PNG, which preserves quality and supports transparency.
What is the maximum image size?
The tool supports images up to 10,000 × 10,000 pixels — more than enough for any normal use.
Can I resize multiple images at once?
This tool handles one image at a time — resize, download, then load the next image.
Will resizing reduce quality?
Making an image smaller retains good quality. Making it larger can look slightly blurry — that’s true of any resizer.
Does it work on mobile?
Yes, our Image Resizer is fully responsive on phones, tablets, laptops, and desktops.
