PDF Compressor | Reduce PDF File Size
Reduce PDF file size for email attachments, upload portals, document sharing, and storage limits while checking the output before download.
What the PDF Compressor Reduces
The PDF compressor is for large documents that need to fit email, form upload, client portal, or storage limits. It focuses on reducing file size while keeping the PDF usable.
What to Review After Compression
Open the compressed PDF and check page order, image clarity, readable text, signatures, stamps, and forms. Important documents should always be reviewed before sending.
When Compression May Not Help Much
If a PDF is already optimized or mostly text, the file size may not drop significantly. Scanned image-heavy PDFs usually have more room for compression than clean digital documents.
About This Tool
PDF Compressor reduces the file size of PDF documents by downsampling embedded images, removing metadata, and applying compression to streams. It is used to shrink PDFs before emailing them, uploading to portals with file size limits, or storing in document management systems.
When to Use It
Use this when a PDF is too large to attach to an email, when a government portal or application form has a file size limit, or when compressing a scanned document to save storage space.
How to Use
- Upload your PDF file.
- Select the compression level: low, medium, or high.
- Click Compress to process the file.
- Preview the file size reduction before downloading.
- Download the compressed PDF.
Frequently Asked Questions
Will compression affect the text in the PDF?
Text compression is lossless. The main quality impact comes from image downsampling, so text-heavy PDFs can be compressed aggressively with no visible difference.
Why is my scanned PDF so large?
Scanned PDFs store each page as a high-resolution image, which can be many megabytes per page. Reducing the scan resolution or image quality during compression can produce dramatic size reductions.
What is a reasonable target size for an emailed PDF?
Most email servers accept attachments up to 10 MB. Aim for under 5 MB for reliable delivery. Government and HR portals often have limits of 2 MB or lower.
