Upload your first PDF

KeenDraft accepts standard PDF files up to 25 MB on Free and 50 MB on paid plans. We validate the file's magic bytes server-side — renaming a non-PDF to .pdf will fail with a clear error.

Scanned PDFs (images of paper) work fine. The signer just won't be able to copy/paste text from them.

• "Not a valid PDF" — usually means the file is actually an image (JPG/PNG) or something else with a forced extension. Open it in a PDF viewer to confirm.
• "Could not parse the PDF" — the file is corrupted. Re-export it from the original source.
• "… is password-protected" — the PDF needs a password to open. Remove the password and upload it again. A PDF that only restricts printing or editing uploads fine.
• More than 1,000 pages — split the document and upload the parts together.
• "File is too large" — compress it. Most PDFs can shrink 40–60% with your PDF tool's "reduce file size" export or any browser-based compressor.
