Security & Privacy

Are my uploaded files safe and private?

Absolutely. We take your privacy very seriously. All uploads use top-tier 256-bit SSL encryption. Your files are used only for the requested operation and are automatically and permanently deleted from our servers within 60 minutes of processing.

Do you read or share my documents?

No. Our conversion processes are entirely automated. Human eyes never see your files, and we never share, sell, or analyze the content of your documents for any purpose other than performing the requested conversion.

Are some files processed on my device?

Yes. For many of our image tools, we utilize advanced WebAssembly technology that processes the files entirely within your browser. This means the file never even leaves your device, providing the ultimate level of privacy.

Technical

What is the maximum file size I can upload?

Currently, the maximum file size per upload is 100MB to ensure fast processing for all users. You can process multiple files in a single session. We are continuously working on optimizing our infrastructure to raise this limit.

Which file formats are supported?

We support over 55 major file formats across all categories. This includes archives (ZIP, RAR, TAR), documents (PDF, DOCX, XLSX, PPTX), images (JPG, PNG, WEBP, SVG, GIF), and data formats (CSV, JSON, XML).

Why did my conversion fail?

Conversions usually fail for three reasons: the uploaded file is corrupted or password-protected, the file exceeds our 100MB size limit, or your internet connection dropped during the upload. If you continue experiencing issues, please use our Contact page to let us know.
