Resize Image Online — Free, No Upload
Resize JPG, PNG and WebP by pixels or percentage. Keep the aspect ratio or set exact dimensions. No upload, no watermark.
How it works
Change the dimensions of a photo without installing anything. Set an exact width and height, or scale by percentage — the aspect ratio lock is on by default so your picture will not come out stretched.
Like every tool here, resizing happens on your device. There is no upload, no waiting for a server, and no watermark on the result.
How to use it
- Choose an image.
- Enter a new width or height, or a percentage to scale by.
- Toggle the lock if you want to set width and height independently.
- Download the resized image.
Why this runs in your browser
Every tool on this site runs 100% in your browser. Your files are never uploaded to any server. That means no upload wait, no third party holding a copy of your data, and it keeps working even if your connection drops.
Frequently asked questions
Will resizing make my image blurry?
Making an image larger always adds blur, because there is no extra detail to invent. Making it smaller usually looks fine. The tool uses smooth scaling to keep downscaled results sharp.
Does it keep the original aspect ratio?
Yes, by default. Turn off the lock icon if you need exact dimensions that do not match the original shape.
Can I resize several images at once?
Not in this version. Batch processing is planned — tell us through the feedback link if you need it.
Is there a maximum resolution?
No fixed limit. Your device memory is the practical ceiling.
