Tips for the best results
- For photos, JPG at 80 to 90% quality gives small files that still look sharp.
- Use PNG when the image has text, a logo or a transparent background.
- PDF to Word works best with PDFs that have real text. For scanned PDFs, use the Image to Text (OCR) tool.
- To shrink a video, choose MP4, Smaller file and 720p in Options.
- Merge PDF keeps the order of your list. Use the arrow next to a file to move it up.
- Big videos convert faster on a computer than on a phone, because all the work happens on your device.
