Frequently asked questions

Yes. Every tool is free with no sign-up, no watermark and no limit on how many files you process or how many edits you make. The site is supported by voluntary donations.

Almost every tool runs inside your browser, so the file never leaves your device. The exceptions are the AI tools (AI Write, Summarize and Translate), which send the text you enter to an AI provider, and they tell you so before you run them.

Yes. Open Edit PDF, click any line of text, picture or shape and change it. The original font, size, colour and position are kept, and the old content is removed from the file rather than just covered up. Scanned pages are pictures, so run OCR first to make their text editable.

Yes. Bengali text is shaped correctly when you add it to a PDF, and PDF to Markdown pulls out proper Unicode Bengali text. Some very old PDFs use non-Unicode legacy fonts, which can limit what any tool can recover.

Pages you don't touch are left exactly as they were. On the pages you change, only the items you edit are rewritten, so the rest of the layout, fonts and images stay in place.

There is no limit set by us. Because files are processed on your own device, the practical limit is your device's memory. Very large PDFs (hundreds of megabytes) can be slow on phones.

PDF tools (edit, merge, split, compress, convert, sign, protect), image tools (resize, crop, compress, convert, effects, OCR), AI Write tools (paragraphs, rewriting, grammar, emails, social posts) and file tools (CSV, JSON, XML, Excel, ZIP, QR codes, hashes).

No. FileDeck runs in any modern browser on Windows, macOS, Linux, Android and iOS.
