Fast image conversion
Convert the folder instead of one image at a time.
Useful for websites, ecommerce images, screenshots, photo collections and other groups of images that need the same output format.
WEBP output
Convert JPG and PNG images into modern WEBP files for web use.
JPG output
Create widely compatible JPEG images with adjustable compression quality.
PNG output
Convert compatible source images to PNG when lossless output is preferred.
Batch resizing
Set maximum width and height while keeping each image's aspect ratio.
Local processing
Images are converted on the user's device instead of being sent to a cloud conversion service.
Desktop app planned
The desktop version can handle entire folders.
The web tool handles common browser-compatible formats now. A downloadable desktop converter could expand this into a much larger offline image-processing utility.
Convert complete folders
Select an entire source folder and process hundreds or thousands
of images in one batch.
More image formats
Add support for TIFF, BMP, HEIC, AVIF and other formats that need
native image libraries.
Batch naming rules
Rename converted files using prefixes, suffixes, numbers or
custom filename patterns.
Preserve folder structure
Convert image folders while maintaining subfolder organization.
Strip metadata
Optionally remove image metadata during batch conversion.
Fully offline operation
Process large or private image collections without uploading them.

formats such as TIFF and HEIC, metadata removal, naming rules,
preserved folder structures and much larger batch processing.
