PDF Editor Free

Open a PDF and click on any page to add text, highlights, rectangles, white-out, images or a signature. Move and resize items, then download your edited copy.

Choose a PDF to editor drag and drop here — files never leave your device

Fill, fix and mark up

Fill in a form that isn't fillable, correct a date with white-out and new text, highlight the clauses a client needs to read, or stamp 'PAID' on an invoice — all without installing desktop software.

Edits are added on top

Like most free editors, this tool adds new content on top of the page rather than rewriting the original text. White-out plus a text box is the reliable way to 'change' existing wording.

FAQ

Frequently asked questions

Are my PDFs uploaded to a server?

No. Every PDF tool on Pyalm runs entirely in your browser using JavaScript — your files are read, processed and saved on your own device and are never sent to us or anyone else. That makes them safe for contracts, invoices and ID documents.

Can I edit the existing text?

You can cover existing text with a white-out box and type the replacement on top. Directly re-flowing the original text isn't supported, because PDFs store text as positioned glyphs rather than editable paragraphs.

Is white-out the same as redaction?

No. White-out hides content visually, but the original text may still exist underneath and be extractable. For true redaction of sensitive data, flatten the result with Compress PDF's strong mode so each page becomes an image.

Can I add a signature?

Yes — draw it with your mouse or finger, type it, or upload an image of your signature, then place it on the page. See the Sign PDF tool for a signature-first workflow.
