Questions about compress pdf
Will the text still be selectable?
No. This works by rendering each page to an image, so the result is a document of pictures — text cannot be selected, copied or searched afterwards. That is a real trade, and it is the wrong tool for a contract someone needs to search. Keep your original.
Why did my file get bigger?
Because it was mostly text. A rasterised page is larger than the vector one it replaces, so a text-only PDF grows rather than shrinks. The tool tells you when that happens and does not offer the result for download.
How much smaller will it get?
For scans and image-heavy documents, often a great deal — the saving is shown before you download anything. For text documents, none. Try Balanced first and drop to Small if it is still too large.
Is my file uploaded?
No. This tool runs entirely in your browser — the file is read from your device, processed there, and never sent anywhere. You can confirm it by disconnecting from the network after the page loads; the tool still works.
Is there a file size limit?
100MB. The limit is your device's memory rather than a policy: beyond that the browser tab tends to run out of memory rather than simply being slow.
Do I need an account?
No. Signing in only adds a library, so your results are still there when you come back.
Something wrong with this tool?
If it gave you the wrong answer or would not do what you needed, we would rather hear about it than not.
