About this tool
A 1 MB limit is common for email attachments and government or university upload forms.
Even longer scanned documents usually fit in 1 MB with sharp text and photos.
The tool shrinks the photos and scans inside the PDF step by step until the file fits. Text and drawings are never changed, so typed text stays sharp and searchable.
Frequently asked questions
Are my files uploaded to a server?
No. Everything happens inside your browser, on your own device. Your files are never sent anywhere, and the tool keeps working even if you go offline after the page has loaded.
What if my PDF can’t get under 1 MB?
The tool tells you the smallest size it could reach. Split the PDF into parts with Split PDF, or remove pages you don’t need, then try again.
Can it compress a password-protected PDF?
No. Remove the password first, then compress the file.
Is it free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
