Questions and answers
How do I compress a PDF to 1 MB or 2 MB?
Type the number into “Not larger than, MB”. The editor picks the best-quality option that fits.
Will text get blurry?
Images inside the PDF are compressed; text stays sharp and searchable.
Why does the file not get smaller?
A text-only PDF is already compact. Scans and photos shrink the most.
Is it safe?
Yes. Compression runs in your browser and the file is never uploaded.
