How can I reduce or decrease the size of a PDF for cloud printing on my pc?
I need to print PDF learning materials for my kids but the EPSON printer does not support PDF files larger than 50MB for cloud print. The current PDF is over that limit, so it can't be uploaded or se...
You can definitely use Libre Office to decrease the size of the PDF on your Windows 10 PC. Totally. It’s not just a Word clone. Libre Office has a feature that lets you "re-export" your PDF. When you do that, you can tell it to squeeze the images inside, which is usually what makes the file huge in the first place.
How to actually do it:
1. Open it up
- Launch Libre Office. Don't just double-click the PDF yet. Open the program first, then go to File > Open and select your big PDF.
2. Find the right export option
- Go to File > Export As > Export as PDF. This opens a box where the magic happens.
3. Crank down the settings
- Look for the Images section.
- Compression: Switch it from "Lossless" to JPEG compression. Lossless keeps 100% quality but makes a massive file.
- Quality: This is the slider that saves you. The default is usually 90. Drop this down to around 50% or 75%. The lower the number, the smaller the file (and slightly lower the quality).
- Resolution: Change this to 150 DPI. Unless you're printing a professional photo for a wall, 150 DPI is totally fine for homework sheets.
4. Save it
- Hit Export, give it a new name so you don't overwrite the original, and you're done.
A user on a help forum did this exact thing with a manual. They dropped the image resolution to 150dpi and the quality to 33%, and the file shrank from 17.2MB down to 5.32MB—massive difference. Next , you can decrease the size of the PDF on Windows 10 computer via Libre Office.
