PDF Compressor – Reduce PDF Size Without Losing Clarity

Large PDF files can be slow to upload, share, or email—especially when they contain a lot of images or scanned pages.
This PDF Compressor Tool helps you quickly reduce the file size of your PDFs while keeping them clear and readable.

Just upload your file, adjust the quality if needed, and download the compressed version. No software installation, no signup, no complicated steps.

How to Use the PDF Compressor

Using this tool is simple and beginner-friendly:

1. Click on “Choose PDF Files” and select one or multiple PDF files from your device.
2. (Optional) Set a Global DPI and Global Quality for all files.
   • Higher DPI = better quality, larger size
   • Lower DPI = smaller size, lighter file
3. (Optional) Click the ⚙️ settings icon next to any file to set individual DPI & quality only for that file.
4. Once you’re ready, click on “Compress PDF(s)”.
5. Wait while the tool processes your files—progress will be shown in the status area.
6. After completion, you’ll see the compressed file name, new size, and original size, along with a Download button for each file.

You can also use the Reset button to clear all files, results, and settings and start fresh.

Key Features of This PDF Compressor

This tool is designed to be practical, flexible, and easy to use:

• Multiple PDFs at once – Upload and compress more than one file in a single go.
• Global Settings – Set a default DPI and quality that applies to all files.
• Per-File Settings – Need different quality for a specific file? Use the ⚙️ settings button to override DPI and quality for that file only.
• Quality Control – Convert each page to a high-quality image and rebuild the PDF with optimized settings.
• Before & After Size Info – See how much space you saved with original and compressed size in MB.
• Browser-Based – Works directly in your browser using JavaScript. No upload to a server is required in typical implementations (depends on your configuration).
• Mobile-Friendly Layout – Optimized for both desktop and mobile screens.

What Are DPI and Quality?

To give you better control, the tool lets you adjust two important options:

• DPI (Dots Per Inch):
  Controls the resolution of the pages when they are converted to images.
  • Higher DPI → sharper pages but bigger file size
  • Lower DPI → smaller file size but slightly reduced clarity
• Quality (%):
  Controls the JPEG image compression used inside the PDF.
  • Higher quality (e.g., 80–90%) → better visuals, more size
  • Lower quality (e.g., 60–70%) → more compression, smaller size

If you’re not sure what to choose, you can simply keep the default values (like 144 DPI and 75 quality) for a good balance between clarity and file size.

When Should You Use This PDF Compressor?

This tool is extremely handy when:

• You need to email a PDF but the size limit is too low
• You are uploading documents to a government portal, job application, or online form
• You want to save storage space on your device or cloud drive
• You are sharing documents on WhatsApp, Telegram, or other platforms that restrict file size

Instead of re-scanning or editing the PDF again and again, you can simply compress it once and share the optimized version.

FAQ – PDF Compressor

Yes. You can upload multiple files together and compress them in a single click.

Q3. What is the purpose of Individual Settings (⚙️ button)?
Individual settings allow you to set a custom DPI and quality for a specific file without changing the global defaults.

This tool is designed to be used as a free, browser-based PDF compressor. You can compress as many documents as you like (subject to your website’s own policy).
