How to use
Compress a PDF to reduce file size while keeping readable quality.
Steps
- Click “Select file” and choose your PDF (or image) from your device.
- If the tool shows extra options, configure them before running.
- Click “Run tool” and wait until processing finishes.
- Click “Download result” to save the output.
Tips
- If a file fails, try “Repair PDF” or “Unlock PDF” first (for damaged or password-protected PDFs).
- For best results, use modern Chrome/Edge and keep the tab open during processing.
- If quality is too low, try recompressing with fewer passes (or avoid double-compressing).
For more advanced options and additional formats you can also use the original React app version.
