How to convert HEIF to PBM
To convert HEIF to PBM, upload your HEIF file, choose PBM as the output format and press Convert. The finished PBM file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter changes HEIF images into PBM files in seconds, with no software to install and no watermark. You can convert several files at once, resize them and choose the quality for formats that support it. Metadata such as location tags is removed from the output for privacy.
Reasons to switch from HEIF to PBM
- Simplest possible image format
- Tiny for line art
- Easy for scripts to handle
- Works with: GIMP, ImageMagick, Netpbm and most scientific tools
What to expect from this conversion
- HEIF is lossy and PBM is not, so the file will usually get larger. Converting cannot bring back detail that HEIF compression already removed.
- PBM has no transparency, so transparent areas are filled with a background colour. White by default, and you can choose another colour in the options.
- PBM cannot store animation here, so only the first frame of an animated HEIF is saved.
- PBM is pure black and white, so every pixel becomes either black or white and photographs lose their tones.
- Browsers do not display PBM files, so use it in editors, print workflows or development tools rather than on a web page.

Steps to convert HEIF to PBM

- Check that PBM is selected as the target and adjust the options if you want.
- Press Convert, then download your new PBM file when it finishes.
Tips for the best result
- Use quality 80 to 90 for photos: it is visually close to the original at a much smaller size.
- Set a width if the image will be shown on a small screen, which also reduces the file size.
- Choose a background colour before converting transparent images to a format without transparency.
