PBM to PNG
- Step 1: Add your PBM image(s) using the upload box on the left. You can queue up to 20 files at once, and large files are welcome. If you want a specific output size, set the width and height in the settings below.
- Step 2: The conversion from PBM to PNG starts automatically. It is quick, and multiple files run in parallel. Tip: PBM is pure black and white; if you upscale, anti-aliasing can introduce soft grays. For the crispest line art, try even multiples like 2x or 4x.
- Step 3: Download your PNG. When you convert more than one file, you will get a single ZIP containing all results. The PNGs will keep the original black-and-white look; PBM does not carry transparency or color.
You can upload up to 20 images simultaneously. Large files are fine, and there are no strict usage limits beyond fair use.
