THREE SMALL STEPS
How to use Compress PDF
Start with your file.
Select .pdf files from your device. Use unencrypted documents within the limits shown above.
Check the upload notice.
Read the upload notice, then choose whether to send your file for temporary processing.
Take the result with you.
Download your PDF and review it before sharing. Files are not stored for later retrieval.
What should I check before sharing the result?
Reopen the downloaded file and check the pages, layout and any added text or form values. Font support and complex PDF features can vary. Standard overlay text supports common Latin characters; unsupported characters produce an error rather than being silently dropped. Existing digital signatures may no longer be valid after editing.
