Common use cases

How to use this tool

Practical tips
- Keep aspect ratio enabled when you want to avoid stretched or squeezed images.
- Use square sizes such as 300x300 or 512x512 for avatars and icons.
- Resize first, then compress, when both dimensions and file size matter.
Why use this tool
- Resize, compress, or convert common image files without installing desktop software.
- Prepare images for upload forms, profile pictures, thumbnails, documents, and web pages.
- Keep image processing local in your browser so your files are not uploaded to ToolNova.
FAQ
Are my images uploaded to a server?
No. The image is processed locally in your browser with canvas APIs and is not uploaded to ToolNova.
Why is the final file size not exactly the target size?
Browser image encoding is approximate. The tool aims to get close to the target while keeping the image usable.
Which image formats are supported?
Most modern browsers support common JPEG, PNG, and WebP files. Support may vary slightly by browser.
