What you can do in version 1.4
New in 1.4
Powerful PDF compressor
Compress PDF files directly on your device with High Quality, Balanced, or Maximum Compression. Compare original and compressed size, keep the source file untouched, and save or share the optimized copy.
- High Quality
- Balanced
- Maximum Compression
Your file stays on the device. The result shows the original size, the compressed size, and the reduction percentage. Supports PDFs up to 100 MB — large files need more memory and can take longer.
