Image Resizer — free online tool
Resize by maximum edge, fixed width or height, or percentage—common for passport-style dimensions, banner crops, and thumbnail batches.
Good for email attachments, CMS uploads, and faster page loads without installing desktop software.
How to use Image Resizer
- Select a photo on the Image Resizer.
- Enter max edge, fixed width/height, or percentage scaling—whichever controls are visible.
- Apply resize and review dimensions reported on the card.
- Download the scaled image for thumbnails, ID forms, or CMS requirements.
Practical tips
- Resize by max edge to fit both portrait and landscape images under one limit.
- Lock aspect ratio unless you intend to stretch—free resizing distorts faces and logos.
- Downscaling is clean; upscaling cannot add detail that was never captured.
Limitations
Image Resizer depends on what your browser can decode (HEIC, SVG, animated GIF, etc.). Output quality and colour profile may shift slightly compared with desktop Photoshop.

Frequently asked questions about Image Resizer
Is the Image Resizer free on Webtoolshop?
Yes. There is no sign-in and no paywall on this page. We may show advertising on some layouts to cover hosting.
Which browsers work best for the Image Resizer?
Chrome and Firefox handle large local files reliably. Safari may struggle with HEIC or very large PDFs—try a smaller file or switch browsers if the preview never appears.
Why did the Image Resizer fail or look wrong?
Try a smaller file, fewer pasted characters, or an updated browser. Extensions that block scripts or downloads sometimes interfere—test in a private window if results never appear.
Are my files uploaded when I use the Image Resizer?
No. The file is read in your browser tab and the result is generated locally. Nothing is sent to Webtoolshop servers for in-browser image or PDF tools.
