About TIM to HEIF Conversion
TIM and HEIF (introduced 2015) are both image formats, but they differ in important ways. TIM is a widely used file format. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices.
When you convert TIM to HEIF, the goal is to convert between formats quickly. Converting TIM to HEIF maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your TIM file is decoded and re-encoded as HEIF. The conversion involves 4 steps: (1) your tim file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in heif format, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you need a HEIF file. For the opposite direction, CocoConvert also supports HEIF to TIM conversion.
