Need to reduce PDF size below 50KB or 100KB for government forms, job applications, or university uploads? Set a precise target and the compressor hits it automatically.
Batch Compress Multiple PDFs at Once

Every PDF is compressed locally in your browser using JavaScript. No files are uploaded to any server. Your sensitive documents never leave your device.

Upload Your PDF Files
Click the "Select Files" button or drag and drop your PDF documents onto the upload area. You can add as many files as you need — there is no file count limit. Each file can be up to several hundred megabytes. All files stay in your browser and are never uploaded to any external server.

Choose a Compression Mode
RajTool offers three compression modes to match your needs:
- Smart Compression (Recommended) — Analyzes each page automatically. Text-heavy pages keep their selectable text and vector graphics intact. Only scanned or image-heavy pages are re-encoded. Best for contracts, reports, and academic papers.
- Maximum Compression — Aggressive raster mode. Choose Target Size to hit an exact file size (like 50KB or 100KB for government form uploads), or choose Quality Based for manual DPI and quality slider control.
- Lossless Optimization — Removes metadata, cleans unused objects, and optimizes PDF streams. Zero visual quality loss. Ideal for archiving.

Click Compress PDF
Hit the "Compress PDF" button. The compressor processes every page locally in your browser. You will see a real-time progress indicator showing which file and page is being processed. Smart mode displays page-type analysis results (vector, scanned, or mixed) as it works.
-
Download Your Compressed
PDFs
Once compression finishes, click "Save as PDF" for a single merged file, or "Save as ZIP" to download all compressed PDFs packaged in one archive. The ZIP option is especially convenient when compressing 5, 10, or 50+ files for bulk email, portal upload, or archiving.
Pro Tip: For government form uploads that require exactly 100KB or 200KB, use Maximum Compression → Target Size mode. For office documents where you want text to remain selectable and searchable, use Smart Compression.

Most online PDF compressors upload your files to their servers and use a single compression algorithm. RajTool is different — it processes everything locally with a page-by-page intelligent analysis engine that routes each page to the optimal compression pipeline. Government documents with text stay searchable. Scanned certificates get maximum size reduction. You control the output with 3 distinct modes.
