What is Batch Converter?
Batch Converter is a powerful free online tool that lets you convert multiple images to a different format simultaneously, saving you the time and effort of processing files one by one. All conversions happen entirely in your browser, meaning none of your images are uploaded to any server. Your files remain completely private on your device throughout the entire process. Simply drag and drop or select multiple images at once, choose your desired output format (PNG, JPG, or WebP), adjust the quality setting, and click Convert All. The tool processes each image sequentially and displays real-time status updates for every file, showing pending, processing, done, or error states. Each converted image gets its own download button so you can save results individually. The tool supports PNG, JPG, WebP, and GIF as input formats. You can process dozens of images in a single session depending on your browser's available memory. This is ideal for photographers, designers, and web developers who regularly need to convert large batches of images to a uniform format for consistency across projects.
How to Use
- Upload multiple images at once.
- Set the output format and quality.
- Click 'Convert All' to convert all images.
- Download each image individually.
Tips & Best Practices
- Select all images at once using Ctrl+A (or Cmd+A on Mac) in the file picker to speed up the upload process for large batches.
- Use WebP as the output format for web projects to achieve the smallest file sizes with excellent quality across the entire batch.
- Set quality to 80% for a good default that works well across most image types when batch converting photographs.
- If some conversions fail, check that the source files are valid images. Corrupted or truncated files may cause individual conversion errors.
- Process images in batches of 20-30 at a time for optimal performance. Very large batches may slow down depending on your device memory.

FAQ
How many images can I convert at once?
It depends on browser memory, but generally you can process dozens of images at once. Each file can be up to 50MB.
Are the same settings applied to all images?
Yes, the output format and quality settings are applied uniformly to all images.
What is batch conversion (batch processing)?
Batch conversion applies the same operation to multiple files at once. It is much faster and more efficient than converting files one by one manually.
Are my files uploaded to a server?
No, all processing happens entirely in your browser and no files are sent to any external server. It is completely safe.
What happens if some images fail to convert?
Failed images are shown with an error status while the remaining images are converted normally. You can retry only the failed files.
Can I download all converted images at once?
Each image has its own download button. Please download them individually after conversion is complete.
How many images can I convert at the same time?
There is no hard limit. The practical limit depends on your browser's available memory. Most devices can handle 20-50 images comfortably. For larger batches, processing in groups of 20-30 is recommended.
Are the same quality settings applied to all images?
Yes, the output format and quality slider settings apply uniformly to every image in the batch. All files are converted using identical parameters.
Can I select different output formats for different images?
The current batch tool applies one format to all images. If you need different formats for different files, process them in separate batches or use the single Format Converter tool.
What happens if one image fails during batch conversion?
Failed images show an error status while the remaining images continue processing normally. Successfully converted images can still be downloaded individually.
Can I cancel a batch conversion in progress?
You can close the browser tab to stop processing. Images that have already been converted will need to be processed again since results are not saved between sessions.
Does batch conversion preserve the original file names?
Yes, each converted file retains its original name with the new file extension matching the selected output format.
