About the Compress PDF to 1MB tool
Many job portals, university applications and government websites only accept PDFs up to 1 MB. This tool automatically tests several compression levels and keeps the sharpest version that fits, so you don't have to try again and again. It works best for scanned documents and PDFs with photos. Pages are saved as images, so text in the result can't be selected.

Frequently asked questions
How long does it take?
Usually a few seconds to a minute, depending on how many pages your PDF has. The tool may try a few settings to find the best one.
What if my PDF can't get under 1 MB?
For long documents with many photos, 1 MB may not be possible with readable quality. The tool tells you the smallest size it could reach, and you can split the PDF into parts with Split PDF.
My PDF is already under 1 MB. What happens?
You get your original file back unchanged, so you don't lose any quality.
Is my document safe?
Yes. It's processed in your browser and never uploaded.
