Compress a PDF on your PC, without uploading it
Compress PDF makes PDFs smaller by recompressing the pictures inside them, which is usually where the size is. Pick Strong, Balanced or Light and compress one file or a whole batch. Text stays text, and if a PDF has little to shrink, Toolyn tells you.

How it works
4 steps, start to finish.
Drop the PDFs
One file or many.
Pick a strength
Strong (100 dpi pictures), Balanced (150 dpi) or Light (220 dpi).
Choose names
Keep the usual name, add a word or use a pattern, or replace the originals, which go to the Recycle Bin.
Compress, then carry on
One click adds a password or signs the result, with the new file already in place.
What it can do
Compress PDF, in detail.
Three strengths
Strong, Balanced and Light trade picture sharpness for size.
Turn images grey
Black-and-white pictures for documents that don't need color.
Leaner files
Data streams are compressed and unused objects dropped too.
Honest results
“This PDF can't be made smaller (it has little image data)” instead of a pointless copy.
Batches
Compress a whole folder of PDFs in one go.
Questions
Compress PDF: plain answers.
Will the text still be selectable?
Yes. Only the pictures are recompressed; the text stays as it was.
What about password-protected PDFs?
Remove the password first with PDF Password, then compress. Toolyn tells you when a file has one.
Why didn't my PDF get smaller?
A PDF that's mostly text has little picture data to shrink. Toolyn tells you rather than saving a copy that isn't smaller.
Is my PDF uploaded?
No. It's compressed on your PC.
