No sign-up, ever
No account, no email address, no verification link. Open the page and the tool is already working. We do not want your details and we never ask for them.
Free for life
Not a trial and not a freemium tease. There is no daily cap, no file-size paywall, no watermark, and no premium tier waiting to interrupt you halfway through a job.
Fast, because nothing uploads
Your file is processed on your own device instead of travelling to a server and back. Most jobs finish before a traditional site would have finished uploading.
Questions
Compress PDF — frequently asked
How much smaller will my PDF get?
Scan-heavy and image-heavy documents commonly drop by 60 to 90 per cent. A PDF that is mostly plain text is already small, so the saving there is modest.
Will the text still be selectable afterwards?
No. Compression works by re-rendering each page as an image, which is what makes the saving so large. If you need selectable text or a searchable document, keep the original.
Which level should I pick?
Balanced is right for emailing reports and forms. Use Light for anything you will print, and Strong when you just need to slip under an upload limit.
Is it safe for confidential documents?
Yes — the file is processed in your browser and never sent anywhere, so a contract or medical record stays on your machine.
Is Compress PDF free to use?
Yes — free for life, with no catch. There is no premium tier, no trial that expires and no feature withheld behind a payment. Compress PDF does the complete job at no cost.
Do I need to create an account or sign up?
No. There is no sign-up, no email address to hand over and no account system of any kind. Open the page and compress pdf is ready to use immediately.
Is there a daily limit or a file cap?
None. Use compress pdf as many times as you like, today and every day, with no hourly cap, no queue and no watermark on what comes out. Because the processing happens on your own device rather than our servers, there is nothing for us to ration.
