PDF tools / practical guide
Turn large document pages into JPEG-backed PDF pages when an image-only copy is acceptable.
A practical starting example
A scanned brochure for email, where selectable text is unnecessary.
Turn large document pages into JPEG-backed PDF pages when an image-only copy is acceptable.
Use this as a small trial before applying the operation to your real input. A sample illustrates the workflow; it does not promise a specific result for every source file or device.
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. Use the application’s copy or download option when it is available.
Prepare the input
Choose an input matching .pdf. Review the tool’s file-size limits before selecting a large batch.
Review the available controls
| Control | Starting value | Review before processing |
|---|---|---|
| Render scale | 1 | Check this against your intended raster pdf compressor result. |
| JPEG quality (0.1–1) | 0.65 | Check this against your intended raster pdf compressor result. |
How to decide whether the result is useful
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.
- Compare the output with the unchanged source.
- Check the destination requirement before copying, downloading or uploading it.
- Open the downloaded file in the receiving application and check its actual type, size and contents.
- Use a second representative sample if the first does not cover the difficult part of your input.
Limitations and troubleshooting
Creates a lossy image-only PDF. Text selection, forms, links and signatures are not preserved. Output may be larger.
If the output does not match your intention
Return to the original copy, review the selected input and controls, and repeat with a smaller sample. If the embedded view is unavailable, use the direct tool link at the top of this page. Browser support and device memory can affect file-based workflows.
Questions about this tool
Why can the compressed PDF be larger?
A PDF that already contains efficient text or compressed images can grow when every page is rasterized. Keep the original if the new copy is larger or loses needed functionality.
Can I use the tool from this guide?
The main button opens the working tool on its Tabaix subdomain. An optional embedded view may be added to this guide; the direct link remains available for larger screens, downloads or browser compatibility.
What should I keep before changing the input?
Keep an unchanged source and record any controls you chose. That gives you a comparison point and lets you repeat the task without replacing your original.
