Merge Drive Files into One PDF and Compress
A merged PDF that includes Slides, Charts, and image-heavy Docs can get large quickly. Compressing during the merge keeps the file size manageable without requiring a separate step.
Enabling compression at merge time
The extension includes a compression option in the merge settings. Enable it before clicking Merge to reduce image resolution in the output. This is most effective for files with many high-resolution images or detailed charts.
Choosing the right compression level
Light compression reduces file size modestly while keeping near-original quality. Medium compression is suitable for most email and web sharing. High compression significantly reduces file size but may make images visibly softer at full zoom.
Post-merge compression
If you have already merged and want to compress afterward, free tools like PDF24 can reduce the file size without re-merging. Upload the merged PDF, apply compression, and download the smaller version.
Frequently Asked Questions
Does compression affect text quality?
No. Text in PDFs is vector-based and is not affected by image compression. Only raster images are compressed.
