Frequently asked questions
- Are my images uploaded anywhere?
- No. Resizing happens entirely in your browser, so your images stay on your device. Once the page has loaded it works offline, and you can confirm in the Network tab that no image data is ever sent.
- Can I resize by pixels or by percentage?
- Both. Enter an exact width and height in pixels, or scale by a percentage of the original. With aspect-ratio lock on, changing one dimension updates the other automatically, so nothing ends up stretched or squashed.
- Will resizing lose quality?
- Making an image smaller keeps it sharp. Enlarging past the original can look soft, because the tool can't invent detail that isn't there — for the crispest result, resize down rather than up. The output size is shown before you download.
- What formats can I resize, and can I do many at once?
- It resizes JPG, PNG, and WebP, one image or many at once. In batch mode the same dimensions or percentage apply to every image, and you can download them individually or as a single zip.
- Can I resize to a specific size like 1080×1080?
- Yes. Set any pixel size you need, so you can fit a 1080×1080 social post, a 1920×1080 wallpaper, an email attachment, or a specific upload limit. Enter the exact numbers and the tool handles the rest.
- Does it work on mobile and offline?
- Yes. It runs in any modern browser on desktop and mobile and works offline once loaded. Nothing to install, no signup.
