Frequently Asked Questions

Everything you need to know about image conversions.

What image formats can I convert with PDFRack Image Converter? +
PDFRack supports conversions across all major formats: JPG/JPEG, PNG, WEBP, GIF, BMP, TIFF, and ICO. You can convert any format to any other supported format.
Can I convert multiple images at once in batch? +
Yes! You can upload up to 50 images at once, configure custom compression settings, and download all converted files individually or as a packaged ZIP archive.
What happens to transparency when converting PNG or WEBP to JPG? +
Because JPG does not support alpha transparency, PDFRack automatically composites transparent areas onto a clean background (default white or custom color) to prevent black border artifacts.
Can I adjust the compression quality of converted images? +
Yes, you can fine-tune output quality from 10% to 100% using the compression slider for lossy formats like JPG and WEBP, or choose 100% for lossless encoding.
Are my uploaded images private and secure? +
100% private. All conversions occur in isolated temporary memory sandboxes and are permanently purged automatically within 1 hour. No files are saved or shared.
