Frequently Asked Questions
How do I compress a PDF to 1MB?▾
Upload your file and the tool will apply light compression to reduce its size. The result will get as close as possible to 1MB depending on the original file.
My PDF is 50MB — can it be compressed to 1MB?▾
It depends on the content. Text-heavy documents compress very well. Image-heavy PDFs may not reach 1MB — consider removing unnecessary pages first.
Will the formatting change?▾
No. The tool preserves page layout, text, and formatting. Compression may slightly reduce image quality.
Is there a file size limit?▾
You can upload PDFs up to 100MB for free. There's no limit on how many files you can compress per day.
