How it works
Convert locally in your browser
ViewerPix decodes and converts supported images on your device. Your files do not need to be uploaded to an application server.
Batch conversion without extra steps
Add multiple images, convert them with the same output settings, then download one result or all completed files.
Control image quality
For JPG and WebP output, adjust quality before converting. PNG remains lossless and keeps transparency when possible.

About Free Image Converter Online
This converter keeps the original pixel dimensions by default and changes the file encoding to the selected output format.
Frequently asked questions
Will converting an image change its dimensions?
No. ViewerPix keeps the original pixel dimensions by default and changes the file encoding.
What happens to quality and transparency?
JPG and WebP use adjustable quality. JPG cannot preserve transparency, while PNG and WebP can preserve transparent areas when the source contains them.
Are my images uploaded to a server?
No. Supported image processing runs locally in your browser. Third-party decoder code may be loaded only when a format needs it, but your image itself stays on your device.
Private browser processing
ViewerPix processes supported images on your device. Your image files are not uploaded to a ViewerPix application server for this task.
