Frequently Asked Questions

Everything you need to know about our free, client-side universal file converter.

Are my files uploaded to any external server or saved in the cloud?

No, absolutely not. Unlike traditional online converters that upload your confidential documents to third-party cloud servers, AllFileConverterTool processes 100% of the conversion algorithms locally within your web browser using HTML5 Canvas, WebAssembly, and client-side JavaScript. Your confidential files never leave your device.

How do Merge PDF and Compress PDF work without cloud servers?

Our PDF utilities parse and rebuild the document structure directly within your browser memory using vector stream compression and page reordering. This delivers instant, high-quality results without server wait times or privacy risks.

Can I convert multiple images into a single combined PDF document?

Yes. Our Images to PDF tool supports selecting or dropping multiple PNG, JPG, WebP, BMP, and iPhone HEIC files simultaneously. It automatically analyzes the orientation of each photo (portrait or landscape) and scales it to fit standard A4 page margins with precise centering.

Is there any file size limit or daily conversion limit?

Because conversions run on your device's own hardware memory, there are no arbitrary cloud file size limits or paywalled conversion queues. You can convert as many files as your device memory can accommodate for free.

Does this converter work offline without an internet connection?

Yes. Once the page has loaded in your browser, the processing libraries remain in your browser cache. You can convert documents and photos completely offline without sending any data over the internet.
