Free Online PDF Tools
Merge, split, convert, and edit PDF documents without installing software or uploading anything. Every PDF tool runs entirely in your browser, so your files stay on your device — no accounts, no watermarks, no limits.
Why Use Browser-Based PDF Tools?
Most online PDF services upload your document to their servers to process it. That is a real privacy problem when the document is a contract, an ID scan, a medical report, or company financials — you are trusting a third party to delete your file after processing. Toolorah's PDF tools take a different approach: the PDF is parsed, modified, and rebuilt by JavaScript running on your own machine. The file never crosses the network, which also means there is nothing to wait for — no upload progress bar, no queue, no "premium speed" upsell.
Desktop alternatives like Adobe Acrobat are powerful but expensive and heavyweight for everyday jobs. If all you need is to staple three PDFs together, pull two pages out of a report, turn a folder of screenshots into a single document, or add a line of text to a form, a focused browser tool does it in seconds.
PDF Tool Use Cases
Job Applications
Merge your CV, cover letter, and certificates into a single PDF — most application portals only accept one attachment.
Scanned Documents
Convert phone photos of receipts, IDs, or signed pages into a clean multi-page PDF ready to email or archive.
Reports and Contracts
Extract just the pages you need from a long report, or remove confidential pages before sharing a document externally.
Form Filling
Use the PDF editor to type answers onto a non-fillable form, white-out outdated details, or highlight key clauses.
Privacy and Security
All PDF tools on Toolorah process files entirely in your browser using JavaScript. Your documents are never uploaded, stored, or logged — they stay on your device from the moment you pick them to the moment the result downloads. Closing the tab removes everything from memory.
Frequently Asked Questions
Are my PDF files uploaded to a server?
No. Every PDF tool on Toolorah runs 100% in your browser using JavaScript. Your files are read locally, processed locally, and the result is downloaded straight from your own device. Nothing is ever uploaded, stored, or logged — which makes these tools safe for contracts, invoices, medical records, and other sensitive documents.
Is there a file size or page limit?
There is no artificial limit. Because processing happens on your device, the practical limit is your browser's memory. Documents with hundreds of pages and files of 50–100 MB typically work fine on a modern computer; extremely large files may be slower on older phones.
Do these tools work with password-protected PDFs?
Encrypted or password-protected PDFs cannot be modified without the password, so protected files are detected and reported rather than silently producing a broken result. Remove the password in your PDF viewer first, then use the tool.
Do I need to create an account?
No. All PDF tools are completely free with no account, no signup, no watermarks, and no usage limits — unlike most online PDF services that gate merging or editing behind a subscription after a couple of uses.
