Useful for email, online submission, and reducing the size of scans.
How it works
- Choose PDF — best for scans files from your device.
- Process them locally in your browser.
- Download One scan-optimized image-based PDF.
Limits and support
- Best for scanned or image-based PDFs.
- Pages are rasterized, so selectable text, links, forms, and vector detail are not preserved.
- A source that is already optimized may not become smaller.
Selected file data is processed on your device and is not uploaded to CobaltPebble for processing.
