How does 100% in-browser PDF conversion protect my security?

Unlike standard converters that upload your PDF to a remote cloud server, our tool uses Mozilla's PDF.js WebAssembly library directly within your browser tab. Your document binary data is never transmitted over the internet.

What DPI setting should I select for printing?

For printing, select 300 DPI. This produces an ultra-high-resolution image matching commercial print standards (over 2400 x 3300 pixels for standard A4 or Letter sizes).

Is there any limitation on the number of pages or file size?

No artificial limits exist. The maximum PDF size is determined only by the available RAM memory of your computer or mobile device.

How do I extract only specific pages?

Use the Page Range Filter input (e.g., '1-3, 5, 8') or check/uncheck the thumbnail checkboxes directly in the gallery.

What is the difference between JPG, PNG, and WebP?

JPG is best for photos and compressed documents. PNG is lossless and supports transparency. WebP offers the highest compression ratio with excellent visual fidelity for websites.

Frequently Asked Questions

Everything you need to know about DPI options, file formats, browser performance, and data security.

How does in-browser conversion guarantee 100% data privacy?

Traditional converters send files over the network to remote backend servers. Our converter uses Mozilla's PDF.js WebAssembly engine directly in your browser. All computations happen in your computer's RAM, and no files ever leave your device.

Which DPI resolution is right for my project?

Choose 72 DPI for small web previews and email attachments, 150 DPI for HD presentations and tablet reading, and 300 DPI for razor-sharp physical printing and high-end graphic design.

Can I convert PDFs on my iPhone, iPad, or Android phone?

Yes. The entire tool is responsive and fully optimized for iOS Safari, Chrome for Android, Firefox Mobile, and iPadOS.

How does the 'Download All as ZIP' feature work?

The tool uses the JSZip client-side library to collect all rendered image blobs, compress them sequentially into a single .zip file in browser memory, and initiate a direct download with clean file naming.

Why won't my password-protected PDF convert?

Encrypted PDFs require a password to access embedded vector streams and font tables. Please unlock or remove the password protection on your PDF prior to converting.

Can I use this tool completely offline?

Yes! Once the webpage assets are loaded into your browser cache, you can disconnect your internet connection and convert as many PDF files as you like without sending any data over the web.
