Frequently Asked Questions

What is PDF Tools Online?

PDF Tools Online is a free collection of browser-based PDF utilities — including a merger, splitter, page remover, rotator, image-to-PDF converter, and metadata editor — that run entirely in your browser. No account, no software installation, and no file uploads required.

Are these tools really free?

Yes. All tools on this site are completely free to use with no hidden fees, premium tiers, or credit limits.

Do I need to create an account?

No. You can use every tool immediately without signing up or logging in.

Are my PDFs uploaded to your servers?

No. All PDF processing happens locally in your browser using JavaScript and the pdf-lib JavaScript library. Your files never leave your device and never touch our servers.

Is there a file size limit?

Since processing is local, limits are determined by your browser and device memory rather than our servers. Most modern browsers handle files up to several hundred megabytes without issue.

Which PDF versions are supported?

Our tools work with standard PDF files (PDF 1.4 through 2.0). Encrypted or password-protected PDFs need to be unlocked in their original viewer first. Each tool's page lists any specific input restrictions.

Will the output quality be affected?

No. Our PDF tools perform lossless operations — pages are copied byte-for-byte from your source file. Merging, splitting, removing pages, and rotating do not re-compress or re-encode any page content.

Can I use these tools on my phone or tablet?

Yes. All tools are mobile-friendly and work on any modern browser including Chrome, Safari, Firefox, and Edge on iOS and Android.

Do you store any of my data?

We do not collect, store, or transmit your PDFs or file contents. We may collect anonymized analytics data such as page views and browser type to help improve the site.
