Raster PDF compressor: inputs, results and limitations
Turn large document pages into JPEG-backed PDF pages when an image-only copy is acceptable.
How to use Raster PDF compressor
- Choose the appropriate input file. General limits are 30 MB per file and 100 MB total.
- Review the options before running: Render scale: 1 · JPEG quality (0.1–1): 0.65
- Inspect the preview or result, then download a new file.
An illustrative use case
A scanned brochure for email, where selectable text is unnecessary.
Select a real sample file you are allowed to process. Begin with a short, simple input before attempting a complex document or recording.
What to inspect in the output
Compare the old and new byte sizes and zoom into the smallest print. Lower JPEG quality can introduce blur; a lower render scale reduces detail before encoding.
Where this tool stops
Creates a lossy image-only PDF. Text selection, forms, links and signatures are not preserved. Output may be larger.
Settings and starting values
| Control | Starting value |
|---|---|
| Render scale | 1 |
| JPEG quality (0.1–1) | 0.65 |
Troubleshooting Raster PDF compressor
If the PDF is encrypted or cannot be parsed, use an unlocked copy you are allowed to edit. For DOCX input, use a genuine .docx file rather than a renamed older .doc document. If extracted text is empty, check whether the source is a scan.
