What this tool does
Drop a whole pile of images and convert them all to the same format in one pass. Image Converter Batch does every file in your browser with canvas, so nothing is uploaded. Pick the target format, set the quality for JPG or WEBP, and download each result or all of them together.
Need one image at a time? Use the single Image Converter, or shrink the results with Image Compress.
What you can use it for
- Convert a folder of PNG screenshots to lighter JPG or WEBP.
- Standardize mixed image formats before uploading them somewhere.
- Turn camera shots into WEBP to save space on a website.
- Batch-prepare images for a gallery without a desktop app.

Frequently asked questions
Are my images uploaded anywhere?
No. Every image is decoded and re-encoded in your browser with canvas, so nothing is uploaded. The files never leave your device.
How many images can I convert at once?
There is no fixed limit, but everything runs in your browser, so very large batches of big images use more memory and take longer. Convert in smaller groups if your device struggles.
Why is the quality slider hidden for PNG?
PNG is lossless, so there is no quality setting to tune. The slider appears only for JPG and WEBP, which trade some detail for smaller files.
