Private, local PDF processing

BrightTools reads the selected PDF in your browser and never uploads it. File contents, names and passwords are not sent to analytics. A shared 50 MB and 200-page safety limit keeps memory use predictable on phones and desktops.

Quality and validation

Compression renders each page at a bounded resolution, encodes it as JPEG and checks the real output bytes. Target-size pages use a finite coarse-to-fine search; they never delete pages or create blank or damaged PDFs. The result is reparsed to confirm page count and page dimensions before download.

À savoir

Only known passwords are accepted. This tool does not crack passwords, run dictionaries or bypass access controls. Reader permissions may still apply after decryption.

Questions fréquentes

Can you recover a forgotten password?

No. Only a password you provide is tried, and every retry is manual.

What if the PDF has no password?

The tool detects that state and offers the original file directly.

Are unlocked PDFs uploaded?

No. Decryption and output validation run locally in your browser.
