Why local-first matters

Every popular "free PDF editor" online works the same way: you upload your contract, someone else's server reads it. Featherlight loads the PDF engine into your browser instead. Open a 50 MB file on a plane, annotate it, sign it, OCR it, compress it, save it. Nothing leaves your machine. That's the whole architecture, and it's also why we can sell lifetime licenses: serving you costs us almost nothing.

Pay once. That's it.

Questions people actually ask

Is my PDF really private?

Yes. Viewing, annotating, organizing, form filling, signing, OCR, compression and flattening all run on your own computer, using pdf.js, pdf-lib and the Tesseract OCR engine compiled to run in your browser. The app's security policy only lets it talk to our own site, so your files have nowhere else to go.

What does "lifetime" mean here?

You pay once and keep the product, including updates. We can afford that because a paid user costs us close to nothing per month by design: the work happens on your computer, not on servers we pay for. There are no monthly caps; the tiers differ only in how many devices one license covers.

Which browsers work best?

Chrome and Edge give the full experience, including saving straight back to the original file. Firefox and Safari work too, but saves download a copy instead (the File System Access API isn't available there).

Can I get a refund?

60 days, no questions, matching AppSumo's policy. Direct purchases get the same window. See the refund policy.

Does it edit PDF text?

Yes, line by line. In Edit mode you click a line, type the new wording and press Enter; it's drawn in the same place, size and colour, in the closest standard font (Helvetica, Times or Courier). The old line is covered, not deleted, so it can still be found by copying or searching the file. Paragraphs don't reflow, and the standard fonts cover Western European languages only. Images, watermarks and true redaction are next, and lifetime license holders get them as free updates.

Is this legally binding e-signing?

Featherlight places visual signatures (drawn, typed or uploaded). It doesn't do PKI certificates or audit trails like DocuSign. For most everyday sign-and-return paperwork a visual signature is what's expected.
