Resize an image online — free and private
To resize an image for free, open Klipzo’s editor, type a new width or height in pixels (or pick a percentage like 50% or 200%), and export. It runs entirely in your browser, so nothing is uploaded, there’s no account, and your photo is never sent to a server. Lock the aspect ratio to scale cleanly without stretching.
Resizing changes an image’s pixel dimensions — useful for fitting a forum avatar limit, meeting an email attachment cap, or matching a template that expects an exact size. Klipzo lets you set width and height directly, or scale by percentage with quick 50%, 75%, and 200% presets. Keep the lock icon on to preserve proportions so nothing looks squashed; turn it off when you deliberately need a non-proportional size. Because the math runs on your own device with Canvas, even a 6000-pixel photo resizes the instant you hit apply, with no upload wait.
How to resize an image online
- Open the editor Go to the Klipzo editor and drag your image in, or click to browse. It loads on your device with no upload.
- Open the Resize tool Choose Resize from the tool rail. You’ll see the current width and height in pixels.
- Enter a new size Type a target width or height, or pick a percentage preset like 50%, 75%, or 200% to scale up or down.
- Lock the aspect ratio Keep the lock icon on so width and height change together and the photo isn’t stretched.
- Apply the change Click Apply. The canvas updates to the new dimensions and the live pixel readout confirms the size.
- Export the result Click Export to download a PNG, JPEG, or WebP at your new size. No sign-up, no watermark.
Tips
- For website hero images, resize to around 1600–1920 pixels wide before compressing to keep pages fast.
- Use the 50% preset to quickly halve oversized phone photos for email attachments.
- Resize first, then compress — shrinking dimensions cuts file size more than quality tweaks alone.
- For social avatars, resize to the exact square size the platform lists (for example 400×400) to avoid awkward auto-cropping.
- Turn the lock off only when a layout demands a fixed, non-proportional size such as a banner strip.
Why it’s private
Unlike most “online” editors, Klipzo never uploads your photo. Everything — decoding, editing, and export — happens on your own device inside the browser. There’s no server that receives your file, no account, and no watermark on what you export. See exactly how it works →
Frequently asked questions
Does resizing cost anything?
No — Klipzo’s resizer is free to use with no account, no watermark, and no cap on how many images you resize. The tool itself never charges you.
Are my images uploaded to resize them?
They aren’t. All resizing happens locally in your browser using HTML5 Canvas, so the file stays on your device and is never transmitted to any server.
Can I resize by percentage instead of exact pixels?
Yes. You can scale by percentage with one-tap 50%, 75%, and 200% presets, or type any custom width or height in pixels for precise control.
Will enlarging an image make it blurry?
Scaling up past a photo’s native resolution adds pixels the camera never captured, so it can look soft. Downscaling stays crisp. For the sharpest results, resize down rather than up whenever possible.
How do I keep the aspect ratio the same?
Leave the lock icon enabled. When it’s on, changing the width automatically updates the height (and vice versa) so the image keeps its original proportions.
