About this tool

PDF Viewer — Read, Search and Print PDFs in Your Browser

Open a PDF and read it straight away: smooth scrolling, zoom, thumbnails, bookmarks, search and printing. Everything runs locally in your browser — no upload, no sign-up, no watermark and no file size limit.

Made for Reading

Pages are drawn sharp at every zoom level as you scroll, one page or two side by side, with page thumbnails, the document's bookmarks and night mode for dark rooms.

Find, Select, Print

Search the whole document with every match highlighted, select and copy text, follow links inside the PDF and print it with your browser's own print dialog.

Edit When You Need To

Need to change something? One click opens the same file in the PDF editor — no second upload, because there never was a first one.

How to use it

  1. Drop a PDF on the page or choose it from your device. Installed as an app, Toolula also opens PDFs with a double-click.
  2. Scroll through the pages, or jump with the page number, the thumbnails or the bookmarks in the sidebar.
  3. Zoom with the buttons or Ctrl and the mouse wheel; choose Fit width, Fit page or two pages side by side.
  4. Press Ctrl+F to find words. Every match is highlighted; Enter jumps to the next one.
  5. Print with the Print button or Ctrl+P, or click Edit to change the PDF in the editor.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Toolula processes the document inside your browser tab with pdf-lib and WebAssembly, so the file never leaves your device.

Can I open large PDFs?

Yes. Only the pages near the screen are drawn and pages you have scrolled past are released again, so long reports and scanned books stay smooth. The practical limit is your device's memory.

Can I use Toolula as my default PDF viewer?

Yes, in Chrome and Edge on a computer: install Toolula as an app, then choose it under Open with for PDF files. A double-click then opens the PDF right here.

Does it open password-protected PDFs?

A PDF that needs a password to open has to be unlocked first. The viewer tells you and takes you to Unlock PDF, which also runs on your device.

Is it really free?

Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
