Image Resizer — Free Online, Resize JPG, PNG, WEBP
Resize JPG, PNG and WEBP images to any pixel dimension free online. Batch friendly, in-browser, no upload, no signup.
How to resize images
Drop your PNG, JPG, or WEBP images. Multiple files at once is fine.
Choose Resize-by-Width (each image gets that width, height auto) or Percentage (uniform scale).
Pick the output format and quality.
Click Resize. Each file is processed in your browser; download individually or as a ZIP.
Common use cases
Preparing images for a specific dimension required by a website, social platform, or print template — fitting a header, thumbnail, or avatar size precisely.
Shrinking very large camera or scanner images to a manageable size for email, document attachments, or web publishing without losing important detail.
Standardising a folder of mixed-resolution images to a consistent size before handing them off to designers, developers, or a print workflow.
How it works
Drop your image into the upload area. The original is read into the browser and a preview is generated locally — nothing is sent over the network.
Enter your target width or height. Choose whether to lock the aspect ratio or allow free resizing. The resizer uses the browser Canvas API for fast, hardware-accelerated rendering.
Click resize and download the result. The original file on your device is untouched; you receive a fresh resized copy with the new dimensions.
Privacy by design
We built this tool to demonstrate that powerful file utilities do not require sending your data to a remote server. Every byte stays on your device.
Hosting and bandwidth aren't free, so the site is supported by privacy-respecting display advertising. Ads never have access to your files because the ads run in a separate iframe and the files never leave your browser memory in the first place.
You can opt out of personalised advertising at any time via the cookie banner at the bottom of the page. Functional behaviour of the tools does not change based on your consent — it only affects the type of ads displayed.
Frequently asked questions
Is it really free?
Yes. There are no fees, no monthly limits, and no premium tier. The tools are funded by display advertising.
Are my files private?
Completely. Everything runs in your browser. We don't have a server that sees your files.
Will it work on my phone?
Yes. Every tool is responsive and works on iOS Safari and Android Chrome. Some heavy operations (large videos, complex PDFs) may be slow on older devices because the work happens locally rather than on a server.
Do I need an account?
No. Tools work immediately, with no signup or login.
Can I use it for commercial work?
Yes. There are no restrictions on the type of file you process or what you do with the result, beyond not violating the law or our Terms of Service.
Where can I report a bug or request a feature?
The Contact page lists an email address — we read every message and try to respond within a couple of business days.
