Free image tools for faster, lighter files
Large images are one of the most common reasons a page feels slow, an email bounces or an upload form rejects a file. These three tools handle the everyday fixes: make the file smaller, change its dimensions, or save it in a more efficient format. Processing happens on your device using your browser's built-in image engine.
How to resize an image without changing the aspect ratio
Open the Resize Image tab, choose your file and keep Lock aspect ratio switched on. Type the new width and the height fills in automatically so the picture isn't stretched. Shrinking an image keeps it sharp; enlarging far beyond the original will look soft, because the browser can't add detail that isn't there.
Why convert images to WebP?
WebP is a modern image format supported by all current major browsers. For the same visual quality, a WebP file is often noticeably smaller than a JPG or PNG, and it supports transparency like PNG.
Smaller images download faster, which can help page load times and Core Web Vitals such as Largest Contentful Paint. Converting to WebP doesn't improve search rankings by itself, but a faster page is a better experience for visitors.
JPG vs PNG vs WebP
| Format | Best for | Keep in mind |
|---|---|---|
| JPG | Photos and images with lots of color detail | No transparency; quality drops each time it's re-saved at low settings |
| PNG | Logos, screenshots, graphics with sharp edges or transparency | Photo files get large |
| WebP | Most website images, photos and graphics | Some older software and email clients may not open it |
Image optimization for websites
- Resize images to roughly the largest size they'll actually display at, not the camera's full resolution.
- Aim for quality around 70–80% for photos; the difference is rarely visible.
- Use WebP where your website platform supports it, with JPG or PNG as a fallback if needed.
- Give every meaningful image descriptive alt text on your site.
- Test the finished page with a speed tool to see what's still heavy.

Good to know
- Everything happens in your browser using the built-in image engine, so nothing is uploaded and there is no file queue.
- Compressing saves as JPG, which suits photos. Logos and screenshots with flat color usually look better as PNG or WebP.
- Resizing down keeps quality well. Scaling far above the original size will look soft.
- WebP is supported by all current browsers and normally produces a smaller file than JPG at the same quality.
- Very large images depend on your device’s memory. If a file fails, try resizing it first.
Common questions
Are my images uploaded to a server?
No. The file is read and processed locally in your browser, and the result is created on your device.
Which formats can I open?
JPG, PNG and WebP. Output is JPG, PNG or WebP depending on the job you pick.
Will smaller images make my site faster?
Lighter images reduce page weight, which usually helps. Real page speed depends on many other things too, so measure the page afterwards.
Is there a file size limit?
There is no fixed limit, but very large files can exhaust the memory a browser tab is allowed to use.
