About this batch tool
Batch conversion runs through a bounded task queue: two files are processed concurrently and the queue yields to the browser between files, so scrolling stays smooth even with a hundred-megapixel batch on screen. Progress is per-file and cancellable at any point.
How it works
- 1Drop your images in. Drag and drop, paste from the clipboard, or browse. Whole folders are fine โ the converter picks up every image it recognises.
- 2Tune the output. Pick a format, set the quality or a target file size, adjust dimensions, and dial in the colour. The preview updates as you type.
- 3Download. Save a single file, or grab the whole batch as one ZIP. A ten-second sponsored break comes first โ that is what keeps the tool free.
Tip: check the preview before downloading
The preview runs the exact same pipeline as the download, including quality and the size target. If it looks right in the preview, the file on disk will look identical โ there is no server-side re-encoding step that could change the result.
