How to Compress a PDF to 100KB, 200KB or 1MB

Why You Need a Smaller PDF

Upload portals and email providers cap file sizes: a form might accept a PDF only under 1MB, an application might want each document under 200KB, and email attachments choke past a certain point. Scanned PDFs are the usual culprit — a few scanned pages can easily run to several megabytes.

Compression re-optimises the images and strips redundant data inside the PDF, shrinking the file while keeping it readable.

How to Compress a PDF to a Target Size

Step 1: Open the Compress PDF tool. Step 2: Upload your PDF. Step 3: Let it compress, then check the new file size. Image-heavy and scanned PDFs usually shrink the most — often 50–80% smaller. Step 4: Download the smaller PDF, ready for your email or upload.

Tips to Reach 100KB or 200KB

• Scanned PDFs compress the most, because the savings come from re-optimising the page images.
• Fewer pages = smaller file. If you only need part of a document, use the Split PDF tool to keep just the pages you need before compressing.
• Text-only PDFs are already small, so if yours won't shrink much, it's probably because it's mostly text — in that case removing unused pages is the better lever.

Will It Lose Quality?

For everyday documents and scans the difference is invisible at normal viewing size. Heavily compressing a photo-rich PDF to a very small target will soften images, so aim for the largest size that still fits under your limit.
