PDFtada

Yes. Every tool is free to use, with no daily limit, no sign-up and no paid plan hiding features.

No. Files you create, convert or edit here come out clean, with no PDFtada logo or text added.

No. Your browser does all the work on your own phone or computer, so the file never leaves your device. That makes it safe for IDs, contracts, bank statements, medical records and other private papers.

Yes. Once a page has loaded, PDFtada quietly saves its tools in your browser, so you can turn on airplane mode and keep merging, compressing, converting and signing. It's also the easiest way to check that nothing is uploaded. The one exception is OCR (reading text from scans), which needs the internet once to download each language.

No. PDFtada works in Chrome, Safari, Edge and Firefox on Android phones, iPhones, tablets and laptops. If you use it often, tap "Install app" at the bottom of any page (on iPhone: Share, then Add to Home Screen) and it opens in one tap, even with no internet.

Only in your own browser, never on our side. To save you time, it remembers the tools you use (under Recent tools), the ones you star (under Starred) and your last settings in each tool, like the compression level or your usual watermark text. It never keeps your files, file names or passwords. Clearing your browser's site data for pdftada.com forgets all of it.

There is no fixed limit. Very large files depend on how much memory your device has, so a laptop handles bigger files than an older phone.

Use Compress PDF for documents or Compress photo for pictures and signatures. Pages like “PDF under 200 KB” tell you straight away whether the result fits the limit.
