Compression converts pages to images. Text selection, search, and form fields will not be preserved.

FAQ

Are my PDF files safe?: Yes. Compression runs entirely in your browser using pdfjs-dist and pdf-lib. Your files never leave your device — zero network requests are made.
Will text still be selectable after compression?: No. This tool compresses by converting each page to a JPEG image. Text selection, search, and form fields are not preserved. This is clearly noted before you compress.
What about password-protected PDFs?: Password-protected PDFs cannot be compressed directly. Remove the password first using your PDF viewer, then try again.
What's the maximum file size?: Each PDF can be up to 50MB, and you can process up to 10 files at once. Files are processed one at a time to manage memory.
Which browsers are supported?: All modern browsers: Chrome, Firefox, Safari 16.4+, and Edge. The tool requires OffscreenCanvas support.
Why did my compressed file get larger?: PDFs that are mostly text or vector graphics may get larger when converted to images. The tool warns you when this happens.
