Questions

Frequently asked

Are my files really not uploaded anywhere?

Correct. Every tool on this page uses JavaScript libraries that run inside your own browser tab. Your PDF is read into your browser's memory, processed there, and the result is handed back to you as a download — it never travels over the network to any server, including ours.

Is there a file size or usage limit?

No artificial limit is imposed by us. The practical ceiling is your device's own memory and processing power — very large files (several hundred pages, or very high-resolution scans) may be slow on an older phone or low-memory computer, but there's no daily cap, no account, and no watermark added to your output.

Why is Compress PDF not shrinking my file by much?

This tool rebuilds your PDF's internal structure to remove duplication and enable more efficient encoding — genuinely free, and safe for text-based PDFs since nothing is rasterized. It won't shrink a file the way re-compressing embedded photos would; for a scanned, image-heavy PDF the size reduction will be smaller than a service that recompresses images.

What does OCR PDF actually change in my file?

It reads the words in your scanned pages and lays an invisible text layer over them, so the PDF becomes searchable and you can select and copy from it. The pages themselves are untouched — the scan still looks exactly the same, and the tool does not retype, redraw or let you edit the words printed in the image. Accuracy depends on the scan: clean, straight, high-resolution pages read well, faint faxes and photos of paper read badly, and Arabic recognition is noticeably less reliable than English, so proofread anything that matters.

Which PDFs work with Fill PDF Form?

Only PDFs that were built with real fillable fields (an AcroForm) — the kind where a form-designer added text boxes, checkboxes, radio buttons and dropdowns. Upload one and every field it contains is listed for you to complete, with the dropdowns showing their own real options; fill them in and download the finished file. If a PDF is just a flat printed-looking form with no fields in it, the tool will tell you so — use Sign PDF to place text or a signature on it instead.

Do I need to create an account?

No. Every tool works immediately with no sign-up, no email, and no payment.

Which browsers does this work in?

Any current version of Chrome, Edge, Firefox or Safari on desktop or mobile. Keeping your browser up to date gives you the best performance for larger files.
