How to convert an image
- Add your image PNG, JPG, and WebP can all be converted in the browser.
- Choose the output format Pick JPG, PNG, or WebP and adjust quality if needed.
- Download the converted file Single files download directly; batches are available as a ZIP.
One output format for the whole set
A batch conversion applies the same output format and quality to every file. That is ideal when a CMS, upload form, or client expects a consistent set of JPGs or WebPs. Mixed input formats are fine: PNG, JPG, and WebP can all be processed in the same run.
Each file is handled independently. If one image is corrupt or unsupported, the rest of the batch continues and the error is shown next to the failed file.
File names and ZIP output
Converted files keep their original base names with the new extension. If two source files share a name, a numeric suffix is added so nothing is overwritten. Successful results are packaged into a single ZIP for easy download.

- Per-file status and error messages
- ZIP download for successful results
Transparency in a mixed batch
If the output is JPG, any transparent areas become white. If the output is PNG or WebP, transparency is preserved. For a batch with a mix of logos and photos, WebP is often the best compromise: it keeps transparency and produces small photographic files.
Frequently asked questions
Can I convert different formats in one batch?
Yes. The input can be a mix of PNG, JPG, and WebP. Every file is converted to the output format you choose.
How many files can I convert at once?
It depends on file size and device memory. A few dozen typical images usually work on desktop. Very large batches may be limited by the browser, and errors are reported per file.
Does the ZIP keep the folder structure?
No. Files are placed at the root of the ZIP with their base names preserved. Folder structure is not recreated.
Are my files uploaded?
No. Conversion runs locally in your browser. Nothing is sent to a server.
