How DropToSolve keeps files private
Updated: August 26, 2026
Why browser-side tools avoid uploads, what that means for PDFs and images, and when local processing is the better choice.
Most “free online converters” ask you to upload a file to their servers, process it remotely, then let you download the result. That model is convenient for the provider — and it means a copy of your document briefly (or longer) lives on someone else’s machine.
DropToSolve takes the opposite approach for file tools: the work runs in your browser with web libraries. Your PDF or image is read locally, transformed locally, and saved locally. We do not need the file on our servers to merge pages or compress a photo.
What stays local
Merge PDF, Split PDF, Images to PDF, Compress Image, and Resize Image process the bytes you select in the page. Generators (QR, passwords, color picker) and text/focus tools also run client-side; they do not require uploading documents.
What we still see (and don’t)
Like any website, basic hosting logs may include technical requests (page loads). That is not the same as receiving your document contents. Ads, if enabled later, may use cookies only after consent where required — see Privacy and Cookies.
If you need Romanian e-invoice operations with ANAF sync, that is a different product: SyncBoard by eFacturaFlow. DropToSolve remains the privacy-first utility hub for everyday files.
