Set a size limit
Compressing this PDF changes its bytes and will invalidate the existing signature.
Compression starts when you continue. You can cancel while it runs; once it finishes you'll need to start a new run to change these settings.

Keep your original. Images were re-encoded and may have lost detail, so check the downloaded file before you rely on it. Nothing left this device: the file above was built here and is being saved from your browser's own memory.

Add content, sign or redact a PDF
Choose a PDF, then add text, JPG/JPEG, PNG or WebP images, or a visible signature. You can also highlight existing text or select an existing image and redact it. A signature photo is cleaned locally so its paper background does not cover the page.
Add text, sign and redact
Your PDF, edits, signatures and redactions stay in this browser and are never uploaded. A visible signature is not a cryptographic digital signature.
Assemble a PDF
Add JPG/JPEG, PNG or WebP photos and whole PDFs, or rearrange the pages of one PDF. Every page gets its own card: type a new page number on it, drag it, or use the arrows. Remove the ones you do not want, and insert blank pages where you need them.
Your photos, PDFs and page order stay in this browser and are never uploaded. The new PDF is built in browser memory and saved straight to your downloads.
Batch PDF compression
Choose several PDFs, then download the safe results as one ZIP file. Each PDF is processed in turn in this browser; signed or unsafe files are listed and left out.
