Is it safe to convert files here?

Yes. Communication is encrypted with HTTPS/TLS. Files are processed temporarily and deleted automatically after 48 hours. Office Tools does not access, store or share your file content.

Is there a size limit?

The current limit is 25 MB per file without registration. You can create an account to access higher limits depending on your plan.

Can I convert several files at once?

Yes. You can drag or select multiple files simultaneously. They will all convert to the same format with the same options. Each file produces its own download.

Can I resize or rotate images during conversion?

Yes. In the advanced options you can set width and height in pixels, pick a fit mode (contain, cover, fit, stretch), rotate 90/180/270 degrees and flip horizontally or vertically. Everything applies during conversion.

What happens when I convert a multi-page PDF to image?

Each PDF page becomes a separate image. If the PDF has more than one page, you'll get a ZIP file with all numbered images (page-1.jpg, page-2.jpg, etc.).

Does it work from mobile?

Yes. The converter works in any modern browser: Chrome, Safari, Firefox and Edge on iOS and Android. You can upload files from the gallery or storage apps.
