Convert image formats

You can read and export still JPG, PNG, and WebP images

JPG does not support transparency, so transparent areas are saved with a white background

Yes. Choose multiple supported images and the same output format and quality setting will be applied to each file in sequence, with an independent result status for every image

No. Source images, full file names, output settings, decoded intermediate pixels, generated images, and ZIP files remain on this device and are not uploaded for processing

The tool handles tested still JPG, PNG, and WebP images. Animation and metadata may not be preserved, while WebP support and large-image capacity depend on your browser

Yes. JPG, PNG, and WebP are available as both tested input formats and selectable output formats, so you can choose PNG or WebP for JPG files

No. A JPG source has no alpha channel, so converting it to PNG cannot recreate transparent pixels that are not present in the source

JPG and WebP output use lossy quality settings and are re-encoded, so some visual detail can change even at a high quality setting

Yes. After a batch finishes, you can create a ZIP containing successful converted results only; failed files are not included

No account or installed conversion software is required. Supported file processing runs on this device after the required browser code loads, while page display and ordinary site features may still use a network connection
