About Compress PDF to 1 MB
Most large PDFs are big because of scanned pages or photos. The tool shrinks those images step by step until the file fits under 1 MB, keeping text and lines sharp.
If a PDF still doesn't fit, it saves the pages as compact images as a last resort, and tells you. If even that is too big, splitting the PDF into parts is the answer.
Frequently asked questions
Are my files uploaded?
No. Everything happens in your browser on your own device. Your files are never sent to a server, so they stay private.
Will my scanned certificate still be readable?
Yes. The tool picks the highest quality that fits the limit, so text on scans stays readable.
My form needs a different size
Type it in the size box: any limit in KB or MB works.
