About the PDF Compression Tool
Almost every PDF size problem comes from the same source: images. A scanned document photographed at full camera resolution can easily produce a file of 20 MB or more, while the same pages as clean text would be a few hundred kilobytes. Since most upload forms cap attachments at 2, 5, or 10 MB, compression becomes necessary rather than optional.
This compressor reduces the file by optimising embedded image data and stripping redundant structure, all within your browser. Because nothing is uploaded, it is safe for exactly the documents people most often need to compress โ identity papers, bank statements, medical records, and signed contracts.
How to Use PDF Compression
- Select the PDF you want to compress.
- Choose a compression level based on how much reduction you need.
- Press Compress and compare the resulting size against the original.
- Download the smaller file.
When to Use This Tool
- Getting a document under an upload limit on a government or job portal
- Reducing an email attachment to fit a mailbox size restriction
- Shrinking scanned documents that were captured at unnecessarily high resolution
- Cutting storage use across a large document archive
- Speeding up sharing of a large report over a slow connection
Things Worth Knowing
- Text-only PDFs are already efficient and will compress very little. The gains come from image-heavy files.
- Higher compression reduces image clarity. Check that any small print is still readable before submitting.
- Always keep the original โ compression discards data permanently.

Frequently Asked Questions
Why did my PDF barely get smaller?
Because it was probably already efficient. Text and vector content compress well by default. Meaningful reductions come from PDFs containing large embedded images, particularly scans.
Will text still be readable after compression?
Text itself is not degraded by image compression. Scanned documents are different โ they are images of text, so heavy compression can blur small print. Verify readability before submitting anything important.
How do I hit an exact size like 2 MB?
Try a compression level, check the result, and adjust. If you cannot reach the target, splitting the document into parts is often the more practical solution.
Is my document uploaded to a server?
No. Compression runs entirely in your browser, which is what makes it appropriate for sensitive documents.
