How do I edit a PDF online for free?

Click the Edit PDF tool, drop your PDF file, and you'll see a preview of every page. Click any text on the page — it becomes editable. Type your replacement, press Enter to confirm, then click Save edited PDF when you're done. The edits are made by covering the original text and drawing your new text on top, producing a clean, valid PDF. No conversion to Word required, no signup, no watermark.

How do I sign a PDF online for free?

Open the Sign PDF tool. Create a signature by drawing it (mouse or finger on a pad) or by typing your name in cursive. Then click anywhere on the PDF preview to place it. You can place the signature on multiple pages, then click Save signed PDF. It's a free alternative to DocuSign and Adobe Sign for personal use.

Is Folio a free alternative to Adobe Acrobat?

For most everyday PDF tasks, yes. Folio offers PDF editing, signing, compression, merging, splitting, and more, all free, all in your browser. Adobe Acrobat Pro charges $19.99/month for these features. Folio doesn't replace Acrobat for advanced enterprise needs like OCR on scanned documents, complex form authoring, or encryption certificates.

Are my PDF files uploaded to a server?

No. Folio processes every file entirely in your web browser using JavaScript. Your PDFs never leave your device, are never sent over the network, and are never stored on any server. You can verify this by opening your browser's DevTools Network tab while you process a file — you'll see zero outgoing requests with file data.

How do I add text to a PDF?

Use the Add Text tool. Drop your PDF, click anywhere on the page preview, and start typing. You can choose font size from 6 to 72 points and color (black, rust, blue, red). Press Enter to confirm. Add as many text blocks as you need across as many pages as you need, then save. Perfect for filling out non-fillable PDF forms.

How do I compress a PDF without losing quality?

Open the Compress tool and pick the High quality preset — this typically reduces file size by about 60% with near-original visual quality, perfect for email attachments. For more aggressive compression of around 90%, use Low quality. The tool tests multiple compression strategies and never makes your file larger than the original.

How do I merge PDF files online for free?

Click the Merge tool, drag and drop two or more PDF files, arrange them in the order you want using the up/down buttons, then click Merge PDFs. The combined PDF will download automatically. The whole process happens in your browser — no upload required.

Can I split a PDF into separate pages?

Yes. The Split PDF tool lets you extract specific pages or page ranges. Enter ranges like 1-3,5,7-9 to pick exactly the pages you want into a new PDF.

Can Folio edit scanned PDFs?

Folio's text editor works on PDFs with selectable text — those created from Word, Pages, web pages, etc. Scanned PDFs are essentially images and need OCR (Optical Character Recognition) before text can be edited. Quick test: try selecting text in your PDF reader. If you can highlight individual words, Folio's editor will work. If selecting just makes a rectangle over the whole page, you have a scanned PDF.

What browsers does Folio support?

Folio works on all modern browsers — Chrome, Firefox, Safari, Edge, Brave, and Arc — on desktop and mobile. JavaScript must be enabled.

Why use Folio over iLovePDF or Smallpdf?

Folio's main differentiator is privacy: nothing leaves your computer. Most online PDF tools require uploading your file to their server, where it's processed and held temporarily. For sensitive documents like contracts, IDs, medical records, and financial statements, that's a real privacy concern. Folio sidesteps it by doing the work locally. There are also no daily limits, no signup walls, and no upgrade prompts.
