PCX's RLE compression is decades behind modern image compression technology, working reasonably well on flat-color graphics but poorly on detailed or photographic content. AVIF's AV1-based compression produces some of the smallest file sizes available for a given visual quality, making it a strong choice when archiving digitized PCX artwork or scans where storage efficiency matters.
Converting old PCX files to AVIF can shrink file sizes significantly for detailed content, though AVIF encoding takes more processing time than simpler formats due to its more advanced compression algorithm.
- 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 AVIF.
- Adjust the quality setting to balance file size against visual detail.
- Click Convert. AVIF files are written to your 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
- Dramatic file size reduction compared to PCX's older compression
- Multi-core processing helps offset AVIF's heavier encoding cost
- Option to delete original PCX files automatically once converted
- No recurring subscription or hidden upload limits
How much smaller will my files be after converting to AVIF?
Often significantly smaller for detailed or photographic content, since PCX's older RLE compression isn't nearly as efficient as AVIF's modern algorithm on that kind of image data.
Do all browsers support AVIF?
All current major browsers support displaying AVIF images, though very old browser versions may not, so checking your specific audience's needs is worthwhile.
Can I convert an entire folder of PCX files to AVIF at once?
Yes, Batch Mode handles entire folders, including nested sub-folders, and scales conversion speed across multiple CPU cores.
