PDF Compressor

Reduce PDF file size before sending email attachments, uploading forms, archiving documents, or sharing files with size limits. Upload a PDF, choose a compression level, and download the optimized file.

How to use this PDF compressor

Upload a PDF file up to 10MB, choose a compression level, and run the tool. Balanced quality is a practical default for most documents because it aims to reduce size while keeping text and images readable. Maximum compression is useful when a form or email service has a strict limit. Higher quality is better when the PDF contains detailed images, scanned pages, charts, or material that may be printed.

After compression, compare the original size and compressed size. Open the downloaded PDF before sending it anywhere important. Check that text is readable, pages are complete, links still work where relevant, and images are acceptable for the final use. If the compressed version is not suitable, try a higher quality setting.

How the tool works

The PDF Compressor uses Ghostscript on the server to rewrite the PDF with compression settings suitable for screen, ebook, or printer-style output. This process can reduce the size of embedded images and optimize internal PDF data. Results vary because some PDFs are already optimized, while scanned documents and image-heavy files often have more room for reduction.

Benefits

Compressed PDFs are easier to upload, email, store, and share. Many job portals, government forms, school systems, client portals, and email services limit attachment size. A smaller PDF can save time and prevent failed uploads. It can also reduce storage usage when archiving large numbers of documents.

Common use cases

People often compress resumes, invoices, scanned forms, certificates, reports, brochures, manuals, and application documents. Businesses may compress PDFs before sending quotes or support files. Students may use compression when submitting assignments through portals with strict limits. For legal, financial, or official documents, always review the final output carefully before submission.

Privacy and security note

Uploaded PDFs are processed as temporary files and old temporary files are removed where server permissions allow. Do not upload highly confidential documents unless you fully trust the hosting environment. The tool does not require an account and is designed to keep the workflow simple.
