PCX's 1985-era RLE compression is far less efficient than HEIF's modern HEVC-based compression, especially for photographic or gradient-rich content where PCX's simple compression scheme doesn't perform well. Converting old PCX scans or digitized artwork to HEIF can shrink file sizes considerably, which matters when archiving a large collection of legacy image files.
HEIF also supports 10-bit color depth, well beyond what PCX's older structure typically handles, though the actual benefit depends on whether your source PCX file contains that much color information to begin with.
- Install Turbo Batch Image Converter Pro on your Windows PC.
- Open the app and select Batch Mode for multiple files, or Individual Mode for a single PCX.
- Drag your PCX file or folder into the app window, enabling recursive folder scanning if needed.
- Set the "From" format to PCX and the "To" format to HEIF.
- Adjust the quality setting to balance file size against visual detail.
- Click Convert. HEIF files are written to the output folder, fully offline.
- 100% offline — your legacy image files are never uploaded anywhere
- Bulk conversion of entire folders, including sub-folders, in one pass
- Significant storage savings compared to PCX's older compression
- Multi-core processing for fast handling of large batches
- Option to delete original PCX files automatically once converted
- No recurring subscription or hidden upload limits
Why is HEIF more storage-efficient than PCX?
PCX's RLE compression dates back to 1985 and is far less efficient than HEIF's modern HEVC-based compression, especially for photographic or gradient-heavy content.
Will HEIF files open on older software?
Most current operating systems and recent software handle HEIF without issue, but some older programs may still expect a more universal format.
Can I batch-convert an entire archive of PCX files to HEIF at once?
Yes, Batch Mode with recursive folder scanning handles entire archives, including nested sub-folders, in a single run.
