TTF

TTF (TrueType Font) is a font format developed by Apple and adopted by Microsoft. It stores scalable glyph outlines with hinting instructions for sharp text on screen. TTF is supported by almost every operating system and app, and it is often converted to WOFF or WOFF2 for use on websites.

OTF

OTF (OpenType Font) is a font format developed by Microsoft and Adobe. It can contain TrueType or PostScript outlines and supports advanced typography such as ligatures, alternate characters, and large character sets. OTF fonts work on Windows, macOS, and Linux and are widely used in design and print.

What happens when TTF becomes OTF

Source format

TTF is the font source or target format for this conversion path.

Target format

OTF is the font source or target format for this conversion path.

What changes

The TTF document is interpreted and rebuilt using the layout and editing model supported by OTF.

What is preserved
Readable text, images, and page order are preserved where the OTF format can represent the same document features.
What may be lost
Complex fonts, comments, tracked changes, forms, macros, and exact pagination may change when OTF cannot represent them.
Codec and quality implications
Inspect the output before replacing the source, especially when the formats use different layout, codec, or editing models.
Realistic limitations
Password protection, corruption, missing fonts, macros, embedded objects, and unusually complex layouts can change or prevent conversion.

Conversion steps

  1. Upload a TTF file no larger than 1 GB.
  2. Confirm that OTF is selected as the target.
  3. Start the conversion. A healthy compatible worker begins processing immediately.
  4. Download the OTF file and check the result before deleting your source.

Troubleshooting

The TTF file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The OTF file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.

Privacy and file retention

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
