How do I resize an image?

Drop the image, choose a preset or type custom dimensions, and click Resize. Lock the aspect ratio if you want to avoid stretching.

What sizes do you support?

Any size you type, plus presets for Instagram post (1080×1080), Instagram story (1080×1920), YouTube thumbnail (1280×720), LinkedIn post (1200×627) and more.

Will resizing reduce image quality?

Down-scaling looks great. Up-scaling beyond the original is limited by the source — it won't add detail that wasn't there.

Can I resize multiple images at once?

Yes. Drop a batch and we apply the same dimensions to all of them. Use aspect-ratio lock to keep each image's proportions.

Does it keep the aspect ratio?

Yes if you toggle the lock — adjust one dimension and the other follows. Turn the lock off when you need an exact size.

What format will the resized image be?

The output keeps the input format (PNG stays PNG, JPG stays JPG). Use our format converter if you want to switch.

Is image resizing free?

Yes, free, with no signup and no watermark.

Are my images uploaded to a server?

No. Resizing runs in your browser, so your images stay on your device.

Can I resize images for Instagram or YouTube?

Yes. Pick the platform preset and the dimensions are filled in for you.

Can I resize images on mobile?

Yes. The tool works in mobile Safari and Chrome — pick the image, resize, and save.
