Frequently Asked Questions
How do I reduce a PDF to under 1 MB?
Drop it here with 1 MB selected and click "Compress PDF". The images inside are compressed a little more at each step until the file fits.
Why is my PDF so large?
Usually because of scanned pages or photos taken with a phone, which are stored at full resolution. Compressing those is what makes the file smaller; text takes very little space.
What if it is still over 1 MB?
Split long scans into parts with "Split PDF" and compress each part, or remove the pages you do not need.
Is 1 MB 1,000 or 1,024 KB?
The tool counts 1 MB as 1,024 KB (1,048,576 bytes), as most upload forms do. If a form still says the file is too large, choose 500 KB.
