PBM to PAM questions
How do I convert PBM to PAM?
Add one or more PBM files, click Convert, then download each PAM result or save the complete batch as a ZIP.
Are PBM files uploaded to a server?
No. Conversion runs locally in the current browser tab, and the original files stay on your device.
Can I batch-convert PBM to PAM?
Yes. You can process up to 200 files, save results one by one, or download multiple results in one ZIP file.
What compression quality should I use?
For WebP and JPG, 75–89 is a useful range for most images. Higher values usually increase file size.

Duplicate names are kept unique by adding _(1), _(2), and so on.
