<p>Finding reliable free online tools used to mean juggling dozens of bookmarked websites — one for PDFs, another for images, a third for JSON formatting, and yet another for calculators.

<p>Large PDF files cause email bounces, slow uploads, and rejected government exam applications. Compressing a PDF reduces file size while keeping text and images readable. This guide shows how to <strong>compress PDF online free</strong> using UtilityTools.</p>
<h2>When should you compress a PDF?</h2>
<p>Compress PDFs before attaching to email (many providers limit attachments to 10–25 MB), uploading to SSC/UPSC/Banking portals (often 50–200 KB for photos, 1–2 MB for documents), sharing on WhatsApp, or publishing on websites where page speed matters.</p>
<h2>Step 1: Open the PDF compressor</h2>
<p>Go to the <a href="/tool/compress-pdf">Compress PDF tool</a> on UtilityTools. No signup or software installation is required.</p>
<h2>Step 2: Upload your PDF</h2>
<p>Click upload and select your PDF file. The tool accepts standard PDF documents up to the platform file limit (typically 50–100 MB for media tools).</p>
<h2>Step 3: Choose compression level</h2>
<p>Select a balance between size and quality. For exam forms and scanned documents, medium compression usually works well. For print-ready files, use lighter compression.</p>
<h2>Step 4: Download the result</h2>
<p>Click compress and download the smaller PDF immediately. Compare file sizes before and after to confirm the result meets your upload limit.</p>
<h2>Tips for better compression results</h2>
<ul>
<li>Remove unnecessary pages before compressing — use <a href="/tool/split-pdf">Split PDF</a> first</li>
<li>Scan documents at 150–200 DPI instead of 600 DPI when possible</li>
<li>Convert color scans to grayscale for text-heavy documents</li>

<h2>FAQ</h2>

<p>Goods and Services Tax (GST) affects every invoice, purchase, and business decision in India. Whether you are a shop owner, freelancer, or student learning taxation basics, a reliable <strong>GST calculator</strong> saves time and prevents billing errors.</p>
<h2>What is GST?</h2>
<p>GST is an indirect tax on supply of goods and services. Standard rates include 5%, 12%, 18%, and 28% depending on the product or service category. Calculations split into CGST + SGST for intra-state supply, or IGST for inter-state supply.</p>
<h2>How to use the GST calculator</h2>
<p>Open the free <a href="/tool/gst-calculator">GST Calculator</a> on UtilityTools. Enter the amount, select the GST rate, and choose inclusive or exclusive mode. The tool instantly shows net amount, GST amount, and gross total with CGST/SGST or IGST breakdown.</p>
<h2>Inclusive vs exclusive GST</h2>
<p><strong>Exclusive GST:</strong> GST is added on top of the base price. A ₹1,000 product at 18% GST costs ₹1,180 total.</p>
<p><strong>Inclusive GST:</strong> GST is already embedded in the price. A ₹1,180 inclusive price at 18% contains ₹180 GST and ₹1,000 net.</p>
<h2>CGST, SGST, and IGST</h2>
<ul>
<li><strong>CGST + SGST:</strong> Applied when supplier and buyer are in the same state. Each is half the total GST rate.</li>
<li><strong>IGST:</strong> Applied on inter-state transactions. One integrated tax replaces CGST + SGST.</li>
</ul>
