How do I resize an image without distorting it?

Keep the aspect-ratio lock on: when you change the width, the height is calculated automatically (and vice versa), so the image keeps its proportions.

What size should I use for the web?

For full-width banners, 1920 px wide; for blog and product photos, 1000–1600 px; for thumbnails, 300–600 px. Larger images only make the page slower.

Can I make an image larger?

Yes, but enlarging only stretches existing pixels, so it gets blurrier. To enlarge photos with real detail, use “Upscale image (AI)”.

Does resizing reduce the file size?

Yes. Fewer pixels means a lighter file: halving the width and height leaves roughly a quarter of the pixels.

Are my files uploaded to a server?

No. Everything is processed inside your browser and your files never leave your device. There is no upload, no queue and no temporary storage, so the tool keeps working even if you go offline after the page has loaded.

Yes. There is no sign-up, no watermark and no daily limit. The site is funded by a few unobtrusive ads around the tools, never inside your files.
