Questions & answers.
Privacy & cost
Is iChangePDF really free?
Yes. It's free to use with no account, no trial, no watermark, and no paid "Pro" tier. We cover costs with unobtrusive ads and keep the editor free for everyone.
Are my files uploaded to a server?
No. Everything happens in your browser, on your device. There is no server on the other end to receive your file — when you open a PDF your browser opens it, and when you save, your browser saves it. The document never travels across the internet. You can read the details in our Privacy Policy.
Do I need to create an account or sign in?
No. There's no sign-up, login, or email required. Open a PDF and start editing.
Does it work offline?
Yes. Once the page has loaded, editing runs entirely in your browser and keeps working without an internet connection.
Editing
What can I change in a PDF?
Quite a lot:
- Edit text in place — change a word, number, or date by clicking a paragraph and typing.
- Format text — bold, italic, underline, strikethrough, and change the font, size and colour of selected words.
- Add things — text boxes, highlights, freehand drawing or a signature, and images.
Can I rearrange, rotate, or delete pages?
Yes. Reorder pages by dragging their thumbnails, rotate or delete any page, and add blank pages. There's full undo and redo.
Will my edits match the original formatting?
iChangePDF re-uses the document's own fonts, sizes and layout so edited text blends in with the rest of the page. Where a document's exact embedded font can't be reused, the closest matching font is substituted.
Can I edit a scanned PDF?
If your PDF is a scan or photo, the "text" is actually an image, so it can't be edited as text. You can still add text boxes, highlights, images, or a signature on top of it.
Files & support
Is there a file size limit?
You can open PDF files up to 50 MB.
How do I save my changes?
Click Export PDF to download a fresh copy with your changes — your original file on disk is left untouched. You can also print the edited document straight from the editor.
Which browsers and devices work?
Any modern browser on desktop or mobile — Chrome, Edge, Safari, Firefox and others. There's no app or extension to install.
How do I report a bug or request a feature?
