About PDF Editor

A free PDF editor that works in your browser

WriteDroid PDF Editor lets you change a PDF without installing anything or creating an account. Open a file, click the text you want to change, sign it, fill in a form, then save. There is no watermark, and your file is edited on your own device, so it is never uploaded to a server.

What you can do

  • Edit text. Press Edit text and click any line. Change the words and the new text keeps the same size and colour. Use Find to replace a word everywhere.
  • Add text, images and your signature. Type anywhere on the page, draw or type a signature once and reuse it, or add a logo or a photo.
  • Fill forms. Fillable PDF forms show their fields right away. Click and type, tick the boxes and save.
  • Mark up. Highlight, underline or strike out text. Draw with a pen, add shapes, arrows, ticks and links.
  • Hide things. Whiteout covers a mistake. Redact removes private details for good by saving that page as a flat picture.
  • Manage pages. Drag to reorder, rotate, delete, duplicate or insert blank pages. Add another PDF or photos to merge them. Extract pages or split a long PDF into several files.
  • Finish. Add page numbers or a watermark, set document properties, make the file smaller or save pages as PNG or JPG.

Built for speed on any device

Pages draw as you scroll, so a large PDF opens quickly. It works on phones and tablets with touch, and on computers with keyboard shortcuts: Ctrl Z to undo, Ctrl F to find and Ctrl S to save.

Private by design

Everything happens in your browser. Your PDF is not sent to us or to any AI service. Close the tab and it is gone. Signatures you choose to keep are stored only on your device.

Frequently asked questions

Is this PDF editor really free, with no sign-up?
Yes. Editing, signing, form filling, merging, splitting and saving are free. There is no account, no watermark and no limit on how many files you edit.
Is my PDF uploaded anywhere?
No. The editor runs in your browser, so your file stays on your device. Nothing is sent to a server, which makes it safe for contracts, IDs and forms.
Can I edit the existing text in a PDF?
Yes. Choose Edit text and click a line. You can change the words, size, font style and colour. Text is replaced line by line. PDFs made from scans are pictures, so add new text on top instead.
How do I sign a PDF?
Open the Sign menu, choose Signature, then draw, type or upload your signature. Click the page to place it and drag the corners to resize it. You can save it on your device for next time.
Can I fill in a PDF form?
Yes. If the PDF has fillable fields they appear ready to type in. If it does not, use Add text and the tick tool to fill it in anywhere on the page.
Does redact really remove the text?
Yes. Pages that contain a redaction are saved as flat pictures, so the hidden text can no longer be selected or copied. Whiteout only covers text, so use Redact for anything private.
How do I merge or split PDFs?
Open the Pages panel and press Add to bring in more PDFs or photos, then drag the pages into order. To split, use More, then Split into several PDFs, or select pages and extract them.
Does it work on my phone?
Yes. It works on phones and tablets with touch. Pinch to zoom, tap a tool, then tap the page. Larger files are faster on a computer.
Is there a file size or page limit?
We set no limit. Very large files depend on your device memory, because the work happens on your device.
