→Use OTF for cross-platform compatibility
→Test fonts across different browsers and operating systems after conversion
→Always keep a backup of your original files before converting

Troubleshooting PFM to OTF Conversion

!The converted OTF font has incorrect metrics → advance width and kerning values may differ between formats despite identical glyphs
!OTF file looks heavier or lighter than PFM → font rendering engines handle weight and anti-aliasing differently per format
!OpenType features (ligatures, swashes) lost after conversion to OTF → verify the target format supports advanced typographic features
!Variable font axes missing from the converted OTF → variable font support varies significantly between formats
