Frequently Asked Questions About DAILY UTILITIES & PDF to OVERVIEW Conversion
Everything you need to know about formats, privacy, and browser-based file conversion.
Are my confidential PDF documents uploaded to your servers?
No. All PDF operations (merging, splitting, watermarking, page numbering, and table extraction) use client-side WebAssembly and pdf-lib directly in your browser memory. Your documents are never uploaded.
Is there a file size limit for PDF and image tools?
Since processing is powered by your local device hardware, there are no artificial server upload caps. You can merge, convert, and split large multi-megabyte files smoothly.
Do these tools require a paid subscription or account?
Never. All tools on ConvertSheet are completely free, open to all users, with no subscription tiers or login requirements.
