Before you start
40 MB combined input and 100 MB output. Images are processed sequentially on your device. Animated images become a still frame.
The total input limit is 40 MB. Very large documents or high-resolution images may need more memory than a phone can provide. Choose a smaller file if your browser runs out of memory.
Your files stay with you.
File contents are processed on this device. We do not upload your selected files to a server or save them to a Pactuno account. Closing or clearing the page releases this session’s files. Downloaded results remain wherever you save them.

Is Batch Image Converter free?
Yes. This tool is free to use without an account. You can process files again as needed, within the per-run limits shown above.
Can I use it on my phone?
Yes, in a current browser with JavaScript enabled. Larger files may work better on a computer with more available memory. Processing depends on your device, not a server queue.
Will the output look exactly the same?
Resizing, cropping, color changes and lossy conversion can alter appearance. JPG does not support transparency. Keep the original and compare the preview before replacing it.
