Why Flint
The complete online PDF toolkit
Built around the one job you actually have: get your PDF from where it is to where you need it.
Edit and annotate without leaving your browser
Click any paragraph and type, the way you would in a doc, with our PDF editor. Add comments, highlights, arrows, and freehand notes with the PDF annotator. When the document's ready, our PDF signer handles your own signature or sends a signature request to someone else.
Convert PDFs to the format you actually need
Pull tables straight into spreadsheets with PDF to Excel, reopen a contract as an editable doc using PDF to Word, or turn a deck back into editable slides with PDF to PowerPoint. Need page images? Try PDF to JPG or PDF to PNG.
Organize multi-file, multi-page documents
Stitch several documents into one tidy file with Merge PDF, break a large PDF into pieces with Split PDF, or drag pages into a new order using Reorder PDF Pages. No more print-then-rescan workarounds.
Compress and protect sensitive content
Big PDF blocking your email attachment? Compress PDF shrinks file size without re-saving the text, keeping your document crisp. For sensitive content, Redact PDF permanently removes information rather than just visually covering it — what's gone is gone.
Browser-based
Nothing to install. Tools run on the page so you can get to work in seconds.
Private by default
Files stay tied to your account, processed only for the action you trigger, and never shared.
One editor, every tool
Annotate, sign, redact, and edit text in the same place — no switching between separate apps for each step.
