Questions
Can it open password-protected PDFs?
Yes — you’ll be asked for the password, which is used only inside your browser to decrypt the file. DRM-protected documents (e.g. licensed e-books) are a different thing: the toolkit respects that protection and will not attempt to bypass it.
Is there a file size limit?
No hard limit — it depends on your device’s memory. Documents with hundreds of pages work fine on a typical laptop; very large scanned files may be slow on older phones.
Does it work on phones and tablets?
Yes. The tools are touch-first: tap to place text, drag to highlight, and draw your signature with a finger. Open PDFs from your Files app, email attachments, or any cloud storage app via its share/open dialog.
Will my exported PDF lose quality?
No — your original pages are copied into the new file untouched, and annotations are added as vector content on top. The one exception: pages from encrypted sources are flattened to images at export, since they can’t be copied directly.
Can it edit the PDF’s existing text?
Not yet. The editor adds new content on top of pages (text boxes, highlights, shapes, signatures) — which covers form-filling and markup. Rewriting a PDF’s original text streams is a much deeper operation and isn’t supported.
It’s free — how is it funded?
The site shows advertising to cover its costs. Where consent is required (for example in the EEA and UK), a Google-certified consent prompt asks whether you allow ad cookies, and you can change your choice any time via “Privacy settings” in the footer. This is separate from your documents — your PDF files are never uploaded or read by us or advertisers. See the Privacy Policy for details.
