Frequently Asked Questions
How much can I reduce my PDF file size?
Typical compression achieves 20-80% size reduction depending on the PDF content. PDFs with many images compress the most.
Will compression affect the quality?
Low and Medium compression preserve quality well. High compression may slightly reduce image quality but keeps text sharp.
Is there a file size limit?
No file size limit. All processing is done in your browser, so you are only limited by your device memory.
What happens to my PDF after compression?
Your file is processed entirely in your browser. It never leaves your device. We have zero access to your files.
Can I compress a password-protected PDF?
No. You must unlock a password-protected PDF first using the Unlock PDF tool, then compress the unlocked file.
What if my PDF is still too large to email after compression?
Try the High compression level. Most email clients accept attachments up to 25MB. If the file is still too large, split it first using the Split PDF tool.
