Frequently Asked Questions

How do I compress a PDF without losing quality?

Use the 'Medium' or 'Low' compression preset. These settings reduce file size by optimizing internal PDF structure while preserving text sharpness and image quality.

How much can I reduce a PDF file size?

Typical compression reduces PDF size by 20–70%. Scanned PDFs (image-heavy) compress more than text-only PDFs. A 10MB scanned PDF can often be reduced to 2–3MB.

Can I compress multiple PDFs at once?

Yes! TryDocsy supports batch PDF compression. Upload multiple PDFs and compress them all at once. Each file is processed individually so you can download them separately.

Is it safe to compress PDFs online?

Yes. TryDocsy compresses PDFs entirely in your browser using JavaScript. Your files are never uploaded to any server, making it 100% private and secure.

Can I set a specific target file size?

Yes! Switch to 'Target Size' mode and enter your desired file size in KB or MB (e.g., 1MB, 500KB). The tool will automatically find the best compression level to meet your target.
