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.
When to use Image Resizer
Fit images under max-width rules for email, LMS uploads, or marketplace listing limits.
Good for email attachments, CMS uploads, and faster page loads without installing desktop software.
What Image Resizer does not do
Upscaling does not add real detail. Not a content-aware crop or AI super-resolution tool.
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.
Example
Max edge 1600 px on a 4000 px camera photo before uploading to a marketplace.
