Resize Image Online
Resizing is often the most effective way to reduce file size. A 4000 pixel wide photo is usually unnecessary for a web article, profile upload, or email attachment.
Recommended image widths
- Blog content images: 1200 to 1600 pixels wide.
- Product thumbnails: 600 to 1000 pixels wide.
- Email attachments: 1000 to 1600 pixels wide.
- Small previews: 300 to 600 pixels wide.
Quality plus size
Image file size depends on both pixel dimensions and encoding quality. For best results, reduce dimensions first and then adjust quality. This usually preserves a cleaner image than forcing extremely low quality on a huge photo.
Local workflow
The resizer runs in your browser, which makes it suitable for private screenshots, internal documents, and personal photos that you do not want to upload to an external image service.
