Created a new iWork Pages document, but the mac powered off suddenly. How can I get the unsaved Pages file back?

Please give me a list of your favorite DVD burner, which can keep original video quality and always works.

I have 2 SD cards, and was planning to save all files into one SD Card, but before transfering the files, I accidentally formatted the SD Card, how can I get the formatted files back, pls help.

Large size PDFs are always troublesome to send out or save, here I collect some tips to reduce PDF file size on mac:

# Small Tips (Without using PDF Compressor)
1) Make the images in the PDF file in small size, images are always the reason to keep a PDF file larger;
2) Delete and remove some unnecessary pages in the PDF file;
3) Export PDF to other formats, especially when you are working on a scanned PDF or a PDF mainly composed of images, you can convert to Text, Word or other editable formats;

# Using PDF Compressor
1) Dedicated---Cisdem PDF Compressor
2) Mac Preview(free)
3) smallpdf(online free)

Hi, I got some images and want to copy the text from these files, how can I do this? Any free solutions would be better, thanks in advance.

I googled online and find Mac Automator can convert PDF to JPG for me, if anyone has similar needs, you can try:
1. Launch Automator in Finder>Application.
2. Click on the Automator to run it, then choose “Workflow”.
3. In the Library column, click on “Files&Folders”, then drag “Ask for Finder Items” to the right column;
In the Library column, click on “PDFs”, then drag “Render PDF Pages as Images” to the right column;
In the Library column, click on “Files&Folders”, then drag “Move Finder Items” to the right column;
4. Click on the “Run” icon on the top right and locate PDFs that need to convert to JPG
5. You will find the JPEG files in your designated location. If you want to convert another PDF to JPG with Automator, click “Run” icon and choose the file for conversion.
