Compress PDF files
Shrink PDFs so they are easy to email and store, or convert them to grayscale. Text stays selectable by default.
Open in Document Studio Keep your edits between steps, with undo.
Free to use, with no sign-up. Works on your phone, tablet or computer.
How it works
- Choose up to 20 PDFs.
- Pick how much to shrink them.
- Compress, then download each result.
If a file can’t be made smaller, the original is kept and you are told. “Maximum” and “Convert to grayscale” turn pages into pictures, so text can no longer be selected. A grayscale copy is always made, even if it is not smaller.
When to use it
- Shrink a PDF to meet an email attachment or upload limit.
- Make scanned PDFs smaller so they are easier to store.
- Convert a PDF to grayscale to save space and ink when printing.
Common questions
Will I still be able to select the text?
By default, yes. Text stays selectable. The “Maximum” and “Convert to grayscale” options turn pages into pictures, so text can no longer be selected.
What if the file can’t be made smaller?
The original is kept and you are told, so you never end up with a larger file by mistake. The grayscale option is the exception: a grayscale copy is always made, even if it is not smaller.
Can I compress several PDFs at once?
Yes. Choose up to 20 PDFs, pick how much to shrink them, then download each result.
Is it free, and do I need an account?
It is free to use and there is no sign-up. It works in your browser on your phone, tablet or computer.
