Questions, answered honestly

Open your browser's developer tools, select the Network tab, then run a conversion. You will see no request carrying your file. We would rather you verify this than take our word for it, since every competing tool makes the same claim.

It is free with no account, no daily cap, and no watermark. The honest reason is that your conversions cost us nothing to run: the work happens on your device, so there is no per-file server cost to recover. The trade-off is that processing is bounded by your own hardware and some operations are not possible in a browser at all.

We do not enforce one. Because files are held in memory while they are processed, the practical ceiling is your device's available RAM. A very large file may fail or make the tab unresponsive, which is a real limitation of this approach compared with server-side processing.

No. There is no service worker, so the page has to load over the network each time, and the PDF to Image tool additionally fetches the PDF.js library from a CDN on first use. Your files are still never uploaded — that is a separate matter from working without a connection.

Image decoding relies on your browser, and Chrome and Firefox cannot open TIFF files this way. We have not bundled a dedicated TIFF decoder yet, so those pages currently do not work outside Safari. Use ImageMagick, Preview on macOS, or GIMP in the meantime.

Because the JPG format cannot store transparency at all — there is no alpha channel in the file. Transparent pixels have to be replaced with a solid colour, and we use white. Convert to WebP instead if you need the transparency preserved.

Not with the image converters or editors, which handle one file at a time. The Merge PDF and Image to PDF tools do accept multiple files, up to 20 each.

Adding a real password to a PDF needs encryption support that our browser-side PDF library does not provide. Rather than produce a file that looks protected but is not, the tool reports that it is unavailable. Use Preview on macOS, Adobe Acrobat, or qpdf --encrypt instead.

Never your files. Our host keeps standard server logs, and anything you type into the contact form is sent to us. The privacy policy sets all of this out in detail.
